Invalid version syntax

[Simon-chevolleau]

Expected behavior

conda-env-activate should activate a conda environment after, interactively, selecting it.

Experienced behavior

An error is returned, specifying the version 4.8.3 + a string: "can't". However, I don't fully understand from which application this version is related to.

It looks like an issue with conda itself -- can you show the output of conda -V in your terminal?

[Simon-chevolleau]

Here is my versions:

• conda version : 23.7.4
• conda-build version : 3.28.2
• python version : 3.11.5.final.0

[WhoisDonlee]

I have a similar error. I think it's unrelated to conda.el.

version<("4.8.3" "can't") checks if your conda version is higher than 4.8.3 by running conda -V in a new shell. conda.el grabs the second value, which should be the conda version. Instead, opening a new shell yields an error and "can't" is the second value.

Opening vterm probably shows the error that's causing the issue.

For me it was an issue with the conda python plugin, which unsets the CONDA_PREFIX variable. Setting the CONDA_PREFIX env var fixed it for me.
