I attempt to deploy a Python package with pip
in a virtual environment on an Ubuntu machine, but encounter a permission-related issue. For example:
(TestVirtualEnv)test@testServer:~$ pip install markdown2
terminates by:
error: could not create '/home/test/virtualenvs/TestVirtualEnv/lib/python3.3/site-packages/markdown2.py': Permission denied
I can't sudo
, since it will install the package globally, and not within the virtual environment. I chown
ed site-packages
; ls
shows only directories related to easy_install
, pip
and setuptools
, and nothing related to Markdown.
How to deploy a package in a virtual environment with pip
without encountering permission-related errors?
This question is related to
python
virtualenv
pip
Solution:
If you created the virtualenv as root, run the following command:
sudo chown -R your_username:your_username path/to/virtuaelenv/
This will probably fix your problem.
Cheers
I've also had this happen (by accident) after creating a new venv while inside an existing virtual environment. an easy way to diagnose this would be to see where the python
is symlinked to, i.e. run:
ls -l venv/bin/python
and make sure it points to the appropriate Python binary. For most systems this will be /usr/bin/python
or /usr/bin/python3
. while if it points to an existing virtual environment it'll be something like /home/youruser/somedir/bin/python
. if it's the latter than I'd suggest recreating the venv while making sure that you aren't "inside" any existing virtualenv (i.e. run deactivate
)
In my case, I was using mkvirtualenv
, but didn't tell it I was going to be using python3. I got this error:
mkvirtualenv hug
pip3 install hug -U
....
error: could not create '/usr/lib/python3.4/site-packages': Permission denied
It worked after specifying python3:
mkvirtualenv --python=/usr/bin/python3 hug
pip3 install hug -U
While creating virtualenv if you use sudo the directory is created with root privileges.So when you try to install a package with non-sudo user you won't have permission to install into it. So always create virtualenv without sudo and install without sudo.
You can also copy packages installed on global python to virtualenv.
cp -r /lib/python/site-packages/* virtualenv/lib/python/site-packages/
I didn't create my virtualenv using sudo. So Sebastian's answer didn't apply to me. My project is called utils
. I checked utils
directory and saw this:
-rw-r--r-- 1 macuser staff 983 6 Jan 15:17 README.md
drwxr-xr-x 6 root staff 204 6 Jan 14:36 utils.egg-info
-rw-r--r-- 1 macuser staff 31 6 Jan 15:09 requirements.txt
As you can see, utils.egg-info
is owned by root
not macuser
. That is why it was giving me permission denied
error. I also had to remove /Users/macuser/.virtualenvs/armoury/lib/python2.7/site-packages/utils.egg-link
as it was created by root
as well. I did pip install -e .
again after removing those, and it worked.
You did not activate the virtual environment before using pip.
Try it with:
$(your venv path) . bin/activate
And then use pip -r requirements.txt on your main folder
If you created virtual environment using root then use this command
sudo su
it will give you the root access and then activate your virtual environment using this
source /root/.env/ENV_NAME/bin/activate
