How did you install Mamba?

Latest version of Mamba

Tried in Conda?

I do not have this problem with Conda, just with Mamba

Describe your issue

I use lock files to generate conda environments with micromamba. There is a bug with micromamba where creating an environment with a relative path fails. The steps to generate this require creating an environment in a directory where the parent folder does not exist. Rerunning the environment creation is fixed on the second attempt.

micromamba create --file packages.txt -p new_folder/target_env --yes

Transaction

  Prefix: new_folder/target_env

...

❯ grep 'bin/python' new_folder/target_env/bin/* 
new_folder/target_env/bin/2to3:#!new_folder/target_env/bin/python3.11
new_folder/target_env/bin/2to3-3.11:#!new_folder/target_env/bin/python3.11
new_folder/target_env/bin/idle3:#!new_folder/target_env/bin/python3.11
...

micromamba create --file packages.txt -p new_folder/target_env --yes
Transaction

  Prefix: /home/user/new_folder/target_env


❯ grep 'bin/python' new_folder/target_env/bin/*                       
new_folder/target_env/bin/2to3:#!/home/user/repos/btd/new_folder/target_env/bin/python3.11
new_folder/target_env/bin/2to3-3.11:#!/home/user/repos/btd/new_folder/target_env/bin/python3.11
new_folder/target_env/bin/idle3:#!/home/user/repos/btd/new_folder/target_env/bin/python3.11
...

Note how the prefix value changes when the parent folder ~/new_folder exists. On the second run the shebang for the scripts uses an absolute path and without it, the scripts simply will not run properly.
