New feature of Python extension will change my conda environment settings.

[brettcannon]

Discussed in #22742

^{Originally posted by Roderick-Stinson January 11, 2024}
Because of the feature of python extension, which is Activate Environments in Terminal Using Environment Variables, python extension will delete an environment variable $CONDA_PREFIX,
the show environment contributions file looks like this:

you can see there isn't a variable named CONDA_PREFIX, instead there are CONDA_PREFIX_2andCONDA_PREFIX_3.
this leads to crash of conda

So could you please help solve this question? It's really annoying. My current solution is add export CONDA_PREFIX=/home/wangzihan/miniconda3 in .bashrc

Same. I'm using macOS, zsh, and miniforge installed by homebrew. Even when I turned off the option terminal.integrated.shellIntegration.enabled I can no longer access my python environment installed by conda in the usual way. Seems like it breaks conda's initialization or path configs in .zshrc? Haven't quite got time digging into it yet, but here's my error reports/outputs for your information.

[WARNING]: Console output during zsh initialization detected.

some Powerlevel10k outputs...

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install <package>

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install <package>

and my ms-python.python extension in Environment changes file writes:

- `_CE_M=`
- `XPC_SERVICE_NAME=0`
- `PS1=(envname) ${env:PS1}`

and in .zshrc I have the conda default initialization as

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/homebrew/Caskroom/miniforge/base/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"

    else
        export PATH="/opt/homebrew/Caskroom/miniforge/base/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

and which conda outputs the following function:

conda () {
	\local cmd="${1-__missing__}"
	case "$cmd" in
		(activate | deactivate) __conda_activate "$@" ;;
		(install | update | upgrade | remove | uninstall) __conda_exe "$@" || \return
			__conda_reactivate ;;
		(*) __conda_exe "$@" ;;
	esac
}

Does anyone know what path I should assign to CONDA_PREFIX if I'm to try the workaround mentioned by several users? Thank you!

Hi Brett Cannon (@brettcannon) lethefrost
I resolved that issue by enabling terminal.integrated.inheritEnv setting.

"terminal.integrated.inheritEnv": true

Hi there Okky Mabruri (@okkymabruri) Thank you! It helps a lot! Seems like the new python extension automatically turned it false?

Just for anyone also encountering the same issue: After reactivating this option, the python command still doesn't look for conda's python binaries by default (as possibly configured in shell's rc file). However, after running conda activate envName in the integrated shell, it can eventually find conda's pythons.

Hi all, apologies for the issue. Could anyone send us the debug logs which can help diagnose it:

• Run Developer: Set log level command
• Select Trace
• Run Developer: Reload Window command
• Provide the output:

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Hi there, what settings should these logs be running under, and is there any specific action we should do to ensure wanted information is logged?

[karrtikr]

No special settings needed other than the ones specified. Just open a Python file to activate the extension and make sure to perform the steps to reproduce the issue.

[brettcannon]

Because we have not heard back with the information we requested, we are closing this issue for now. If you are able to provide the info later on, then we will be happy to re-open this issue to pick up where we left off.
