I installed Anaconda 4.4.0 (Python 3.6 version) on Windows 10 by following the instructions here: https://www.continuum.io/downloads. However, when I open the Command prompt window and try to write
conda list
I get the
'conda' command is not recognized...
error.
I tried to run
set PATH=%PATH%;C:\Users\Alex\Anaconda3
but it didn't help. I also read that I might need to edit my .bashrc
file, but I don't know how to access this file, and how I should edit it.
This question is related to
python
python-3.x
windows-10
anaconda
conda
case #1 You should set 3 path:
%ANACONDAPATH%;
%ANACONDAPATH%\Scripts;
%ANACONDAPATH%\Library\bin;
It will solve problem:
C:\WINDOWS\system32>conda update conda
Solving environment: failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/msys2/noarch/repodata.json.bz2>
Elapsed: -
...
case #2 Also you can use Anaconda Promd (for Win10) instead CLI (cmd.exe)
To prevent having further issues with SSL you should add all those to Path :
SETX PATH "%PATH%;C:\<path>\Anaconda3;C:\<path>\Anaconda3\Scripts;C:\<path>\Anaconda3\Library\bin"
When you install anaconda on windows now, it doesn't automatically add Python or Conda.
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
Next, you can add Python and Conda to your path by using the setx command in your command prompt.
Next close that command prompt and open a new one. Congrats you can now use conda and python

If you want to use Anaconda in regular cmd on windows you need to add several paths to your Path env variable.
Those paths are (instead of Anaconda3 the folder may be Anaconda2 depending on the Anaconda version on your PC):
\Users\YOUR_USER\Anaconda3
\Users\YOUR_USER\Anaconda3\Library\mingw-w64\bin
\Users\YOUR_USER\Anaconda3\Library\usr\bin
\Users\YOUR_USER\Anaconda3\Library\bin
\Users\YOUR_USER\Anaconda3\Scripts
\Users\YOUR_USER\Anaconda3\bin
You need to add the python.exe in C://.../Anaconda3 installation file as well as C://.../Anaconda3/Scripts to PATH.
First go to your installation directory, in my case it is installed in C://Users/user/Anaconda3 and shift+right click and press "Open command window here" or it might be "Open powershell here", if it is powershell, just write cmd and hit enter to run command window. Then run the following command setx PATH %cd%
Then go to C://Users/user/Anaconda3/Scripts and open the command window there as above, then run the same command "setx PATH %cd%"
If you have installed Visual studio 2017 (profressional)
The install location:
C:\ProgramData\Anaconda3\Scripts
If you do not want the hassle of putting this in your path environment variable on windows and restarting you can run it by simply:
C:\>"C:\ProgramData\Anaconda3\Scripts\conda.exe" update qt pyqt
I had also faced the same problem just an hour back. I was trying to install QuTip Quantum Toolbox in Python Unfortunately, I didn't stumble onto this page in time. Say you have downloaded Anaconda installer and run it until the end. Naively, I opened the command prompt in windows 10 and proceded to type the following commands as given in the qutip installation docs.
conda create -n qutip-env
conda config --append channels conda-forge
conda install qutip
But as soon as I typed the first line I got the following response
conda is not recognized as an internal or external command, operable program or batch file
I went ahead and tried some other things as seen in this figures error message Finally after going through a number conda websites, I understood how one fixes this problem. Type Anaconda prompt in the search bar at the bottom like this (same place where you hail Cortana) Anaconda prompt
Once you are here all the conda commands will work as usual
Things have been changed after conda 4.6.
Programs "Anaconda Prompt" and "Anaconda Powershell" expose the command conda
for you automatically. Find them in your startup menu.
If you don't wanna use the prompts above and try to make conda
available in a normal cmd.exe
and a Powershell. Read the following content.
conda
in Every ShellThe purpose of the following content is to make command conda
available both in cmd.exe
and Powershell on Windows.
If you have already checked "Add Anaconda to my PATH environment variable" during Anaconda installation, skip step 1.
If Anaconda is installed for the current use only, add %USERPROFILE%\Anaconda3\condabin
(I mean condabin
, not Scripts
) into the environment variable PATH
(the user one). If Anaconda is installed for all users on your machine, add C:\ProgramData\Anaconda3\condabin
into PATH
.
Open a new Powershell, run the following command once to initialize conda
.
conda init
These steps make sure the conda
command is exposed into your cmd.exe
and Powershell.
conda init
from Conda 4.6Caveat: Add the new \path\to\anaconda3\condabin
but not \path\to\anaconda3\Scripts
into your PATH
. This is a big change introduced in conda
4.6.
Activation script initialization fron conda
4.6 release log
Conda 4.6 adds extensive initialization support so that more shells than ever before can use the new
conda activate
command. For more information, read the output fromconda init –help
We’re especially excited about this new way of working, because removing the need to modifyPATH
makes Conda much less disruptive to other software on your system.
In the old days, \path\to\anaconda3\Scripts
is the one to be put into your PATH
. It exposes command conda
and the default Python from "base" environment at the same time.
After conda
4.6, conda
related commands are separated into condabin
. This makes it possible to expose ONLY command conda
without activating the Python from "base" environment.
Even I got the same problem when I've first installed Anaconda. It said 'conda' command not found.
So I've just setup two values[added two new paths of Anaconda] system environment variables in the PATH variable which are: C:\Users\mshas\Anaconda2\ & C:\Users\mshas\Anaconda2\Scripts
Lot of people forgot to add the second variable which is "Scripts" just add that then 'conda' command works.
