how to set CONDA_EXE on MS Windows?

[adrianstaniec]

where and how exactly should I set this variable on windows

I have already tried: C:\Users\adrian\Miniconda3\Scripts\conda.exe /c/Users/adrian/Miniconda3/Scripts/conda.exe

in System Properieties > Environment Variables

and in neovim running :echo $CONDA_EXE it shows the set path

but when I try :CondaChangeEnv I still get:

RuntimeError: $CONDA_EXE is not set to a valid conda executable ($CONDA_EXE='$CONDA_EXE')

I looked into the coda and I tried to come up with mimal example, here output from Window cmd terminal:

C:\Users\adrian>echo %CONDA_EXE%
C:\Users\adrian\Miniconda3\Scripts\conda.exe




C:\Users\adrian>type z.py
from subprocess import check_output, CalledProcessError, PIPE
import json
import os


def vim_conda_runshell(cmd):
    """ Run external shell command """
    return check_output(cmd, shell=True, executable=os.getenv('SHELL'), stdin=PIPE, stderr=PIPE).decode('utf-8')

try:
    output = vim_conda_runshell('$CONDA_EXE info --json')
    print(json.loads(output))
except CalledProcessError:
    cmd = vim_conda_runshell('echo $CONDA_EXE').strip()
    raise RuntimeError("$CONDA_EXE is not set to a valid conda executable ($CONDA_EXE='{}')".format(cmd)) from None



C:\Users\adrian>python z.py
Traceback (most recent call last):
  File "C:\Users\320138242\z.py", line 15, in <module>
    raise RuntimeError("$CONDA_EXE is not set to a valid conda executable ($CONDA_EXE='{}')".format(cmd)) from None
RuntimeError: $CONDA_EXE is not set to a valid conda executable ($CONDA_EXE='$CONDA_EXE')

So it seems that it about the difference between syntax of using %CONDA_EXE% vs $CONDA_EXE.

On the other hand if I try the same thing inside Git Bash terminal, I get:

adrian@adriansmachine MINGW64 ~
$ echo $CONDA_EXE
/c/Users/adrian/Miniconda3/Scripts/conda.exe
(base)




adrian@adriansmachine MINGW64 ~
$ python z.py
Traceback (most recent call last):
  File "C:\Users\adrian\z.py", line 11, in <module>
    output = vim_conda_runshell('$CONDA_EXE info --json')

    return check_output(cmd, shell=True, executable=os.getenv('SHELL'), stdin=PIPE, stderr=PIPE).decode('utf-8')

    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '$CONDA_EXE info --json' returned non-zero exit status 126.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\adrian\z.py", line 14, in <module>
    cmd = vim_conda_runshell('echo $CONDA_EXE').strip()

I've added a pull request (#40) that fixed this for me, by using os.getenv rather than directly referencing $CONDA_EXE.
