Cannot activate environment with (system-wide) conda

[suvayu]

Issue Type: Bug

I have a system wide conda install (/usr/bin/conda). While vscode detects all my conda environments correctly, it fails to activate them correctly, leading to various things not working, like test discovery, starting a jupyter server, etc.

$ conda env list 
# conda environments:
#
aif360                 /home/user/.conda/envs/aif360
arcade                 /home/user/.conda/envs/arcade
decrypted              /home/user/.conda/envs/decrypted
outage                 /home/user/.conda/envs/outage
pa-dev                 /home/user/.conda/envs/pa-dev
py36                   /home/user/.conda/envs/py36
py36-microscopy        /home/user/.conda/envs/py36-microscopy
py37                   /home/user/.conda/envs/py37
base               *   /usr

My understanding is conda calls source activate <env> or equivalent to activate and environment. There is no activate script in my path, so this fails. I have tried setting python.condaPath to /usr/bin/conda, but all it does is call source /usr/bin/activate <env> instead; again that fails.

I found an old issue (#1882) that points to something like my problem, but I couldn't quite find a resolution. If there was an easy way to configure what command is used to activate an environment, that would be great. Maybe a list of command templates that can be tried in order until one succeeds, ["conda activate <env>", "source activate <env>", "workon <env>", ...] and so on.

May be dupe of #7425

There is no activate script in my path

You don't need to have it, we search for the activate script using path to conda interpreter. Anyways, we are moving to using conda run which runs an executable from within a conda environment without activating it. It won't need activate, so this would be fixing all these issues. Closing this in favor of #7425 .
