Describe your issue

This command:

micromamba create -y -p ./testenv -c conda-forge pip

produces this error:

error    libmamba Error opening for writing "testenv\\Scripts\\pip-script.py": No such file or directory
error    libmamba Error opening for writing "testenv\\Scripts\\pip.exe": No such file or directory
critical libmamba permissions: The system cannot find the path specified.: "testenv\Scripts\pip.exe"

It appears to only occur with micromamba v1.4.3 (the latest version on conda-forge) on Windows.

I have observed it locally, in CI and I've had a couple of bug reports with the same issue on a package of mine which depends on micromamba.

Hi, getting this as well.

• Started when updated micromamba from v1.4.2 to v1.4.3 (also reproduces on v1.4.4)
• Works on Linux, fails on Windows

[jonashaag]

Is this the same as #2609?

[wolfv]

Yes, this is very likely the same bug.
