[python] Using pip behind a proxy with CNTLM

I am trying to use pip behind a proxy at work.

One of the answers from this post suggested using CNTLM. I installed and configured it per this other post, but running cntlm.exe -c cntlm.ini -I -M http://google.com gave the error Connection to proxy failed, bailing out.

I also tried pip install -–proxy=user:pass@localhost:3128 (the default CNTLM port) but that raised Cannot fetch index base URL http://pypi.python.org/simple/. Clearly something's up with the proxy.

Does anyone know how to check more definitively whether CNTLM is set up right, or if there's another way around this altogether? I know you can also set the http_proxy environment variable as described here but I'm not sure what credentials to put in. The ones from cntlm.ini?

Under Windows dont forget to set

SET HTTPS_PROXY=<proxyHost>:<proxyPort>

what I needed to set for

pip install pep8

Set up invironment variable in Advanced System Settings. In Command prompt it should behave like this :

C:\Windows\system32>echo %http_proxy%

http://username:passowrd@proxy:port

C:\Windows\system32>echo %https_proxy%

http://username:password@proxy:port

Later , Simply pip install whatEver should work.

You can continue to use pip over HTTPS by adding your corporation's root certificate to the cacert.pem file in your site-packages/pip folder. Then configure pip to use your proxy by adding the following lines to ~/pip/pip.conf (or ~\pip\pip.ini if you're on Windows):

[global]
proxy = [user:passwd@]proxy.server:port

That's it. No need to use third party packages or give up HTTPS (of course, your network admin can still see what you're doing).

Under our security policy I may not use https with pypi, SSL-inspection rewrites certificates, it breaks the built-in security of pip for www.python.org. The man in the middle is the network-admin.

So I need to use plain http. To do so I need to override the system proxy as well as the default pypi:

bin/pip install --proxy=squidproxy:3128 -i http://www.python.org/pypi --upgrade "SQLAlchemy>=0.7.10"

1. For PIP Installation:

ex:PORT = 9090
ex:PROXY_SERVER = stackoverflow
USERNAME:your user id
PASSWORD: your password

• sudo pip2 install PACKAGENAME --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python2.7

• sudo pip3 install PACKAGENAME --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python3.5

Example:

sudo pip2 install pandas --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/

2. For apt-get Installation

sudo http_proxy=http://USERNAME:PASSWORD@PROXY_SERVER:PORT/ apt-get install PACKAGENAME

Example:

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get install tensorrt

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get update

How about just doing it locally? Most likely you are able to download from https source through your browser

1. Download your module file (mysql-connector-python-2.0.3.zip /gz... etc).

2. Extract it and go the extracted dir where setup.py is located and call:

   C:\mysql-connector-python-2.0.3>python.exe setup.py install
   

At CentOS (actually I think all linux distros are similar) run

env|grep http_proxy

and

env|grep https_proxy

check what is the output of those commands (they should contain your proxy addresses).

If the outputs are empty or have incorrect values, modify them, for ex:

export http_proxy=http://10.1.1.1:8080
export https_proxy=http://10.1.1.1:8080

Now try to fetch and install some packages by using pip:

pip --proxy http://10.1.1.1:8080 install robotframework

and actually I have never met the case when it didn't work. For some systems you need to be a root (sudo is not enough).

This is what works for me:

pip --proxy proxy url:port command package

In Ubuntu 14.04 LTS

   sudo pip --proxy http://PROXYDOM:PROXYPORT install package

For windows users: if you want to install Flask-MongoAlchemy then use the following code

pip install Flask-MongoAlchemy --proxy="http://example.com:port"**

It was not working for me. I had to use https at work:

pip install --proxy=https://user@mydomain:port somepackage

In order to update, add -U.

Open the Windows command prompt.

Set proxy environment variables.

set http_proxy=http://user:password@proxy_ip:port
set https_proxy=https://user:password@proxy_ip:port

Install Python packages using proxy in the same Windows command prompt.

pip install --proxy="user:password@proxy_ip:port" package_name

I am also no expert in this but I made it work by setting the all_proxy variable in the ~/.bashrc file. To open ~/.bashrc file and edit it from a terminal run following commands,

gedit ~/.bashrc &

Add following at the end of file,

export all_proxy="http://x.y.z.w:port"

Then either open a new terminal or run following in the same terminal,

source ~/.bashrc

Just setting http_proxy and https_proxy variables aren't enough for simple usage pip install somepackage. Though somehow sudo -E pip install somepackage works, but this have given me some problem in case I am using a local installation of Anaconda in my users' folder.

P.S. - I am using Ubuntu 16.04.

I got the error:

(The proxy server's port is ssh port forwarded to localhost:3128).

I had to set both http and https proxies to make it work:

Cleaning up...

as http://pypi.python.org/simple/ redirects to https://pypi.python.org/simple but pip's error does not tell you.

If you are using Linux, as root:

env https_proxy=http://$web_proxy_ip:$web_proxy_port pip install something

When you use env it exports the variable https_proxy for the current execution of the command pip install.

$web_proxy_ip is the hostname or IP of your Proxy $web_proxy_port is the Port

for windows; set your proxy in command prompt as
set HTTP_PROXY=domain\username:password@myproxy:myproxyport

example:
set http_proxy=IND\namit.kewat:[email protected]:8880

Phone as mobile hotspot/USB tethering

If I have much trouble finding a way through the corporate proxy, I connect to the web through my phone (wireless hotspot if I have wifi, USB tether if not) and do a quick pip install.

Might not work for all setups, but should get most people by in a pinch.

If you are connecting to the internet behind a proxy, there might be problem in running the some commands.

Set the environment variables for proxy configuration in the command prompt as follows:

set http_proxy=http://username:password@proxyserver:proxyport
set https_proxy=https://username:password@proxyserver:proxyport

This worked for me (on Windows via CMD):

pip install --proxy proxyserver:port requests

With Ubuntu I could not get the proxy option to work as advertised – so following command did not work:

sudo pip --proxy http://web-proxy.mydomain.com install somepackage

But exporting the https_proxy environment variable (note its https_proxy not http_proxy) did the trick:

export https_proxy=http://web-proxy.mydomain.com

then

sudo -E pip install somepackage

A simpler approach might be:

1. Create a folder named "pip" in your $HOME directory.
2. Create a file named "pip.ini" (Windows) or "pip.conf" (Linux) in the directory created in step 1

3. Copy & paste the following lines under the pip.ini/pip.conf:

   [global]
   trusted-host = pypi.python.org
                  pypi.org
                  files.pythonhosted.org 
   

for windows go to C:/ProgramData/pip/pip.ini, and set

[global]

proxy = http://YouKnowTheRest

with your proxy details. This permanently configures the proxy for pip.

In Windows 7:

pip install --proxy DOMAIN\user:password@proxyaddress:port package

i.e.:

pip install --proxy BR\neo:[email protected]:8080 virtualenv

Warning, there is something very bad with the "pip search" command. The search command do not use the proxy setting regardless of the way it's being passed.

I was trying to figure out the problem only trying the "search" command, and found this post with detailed explanation about that bug: https://github.com/pypa/pip/issues/1104

I can confirm the bug remains with pip 1.5.6 on Debian 8 with python 2.7.9. The "pip install" command works like a charm.

if you want to upgrade pip by proxy, can use (for example in Windows):

python -m pip --proxy http://proxy_user:proxy_password@proxy_hostname:proxy_port insta
ll --upgrade pip

I solved the problem with PIP in Windows using "Fiddler" (https://www.telerik.com/download/fiddler). After downloading and installing, do the following:

"Rules" => click "Automatically Authenticate"

Example: pip install virtualenv -proxy 127.0.0.1:8888

Just open your prompt and use.

$ pip --proxy http://proxy-host:proxy-port install packagename

This is what worked for me on

Using pip behind a work proxy with authentification, note that quotation is required for some OSes when specifing the proxy url with user and password:

pip install <module> --proxy 'http://<proxy_user>:<proxy_password>@<proxy_ip>:<proxy_port>'

Documentation: https://pip.pypa.io/en/stable/user_guide/#using-a-proxy-server

Example:

pip3 install -r requirements.txt --proxy 'http://user:[email protected]:1234'

Example:

pip install flask --proxy 'http://user:[email protected]:1234'

Proxy can also be configured manually in pip.ini. Example:

[global]
proxy = http://user:[email protected]:1234 

Documentation: https://pip.pypa.io/en/stable/user_guide/#config-file

I could achieve this by running:

pip install --proxy=http://user:[email protected]:3128 package==version

I'm using Python 3.7.3 inside a corporative proxy.

Set the following environment variable: export PIP_PROXY=http://web-proxy.mydomain.com

I had the same issue : behind a corporate proxy with auth at work, I couldn't have pip work, as well as Sublime Text 2 (well, it worked with custom setup of my proxy settings). For pip (and I'll try that on git), I solved it installing cntlm proxy. It was very simple to configure :

1. Edit cntlm.ini
2. Edit "Username", "Domain", "Password" fields
3. Add a "Proxy" line, with your proxy settings : server:port
4. Make sure the line "NoProxy" integrates "localhost" (like that by default)
5. Note the default port : 3128
6. Save and that's it.

To test that works, just launch a new command line tool, and try :

pip install django --proxy=localhost:3128

That worked for me. Hope this will help you.
