   A downside here is that make install no longer works without internet access, even if setuptools>=64 is installed in the environment.

   It's unrelated to this PR. Offline make install worked for pygmt<=0.2.0 and started to fail since v0.3.0, in which we switched from versioneer to setuptools_scm (https://www.pygmt.org/dev/changes.html#id47). So it's likely a problem for setuptools_scm.

   This comment is confusing to me because I tried make install offline on the commit preceding 06fca61 and it worked fine.

   Here are a series of commands I run without internet access:

   # Uninstall PyGMT first
   $ pip uninstall pygmt
   
   # Install the latest main brach (FAILS to find setuptools>=64)
   $ git checkout main
   $ pip install --no-deps -e .
   
   # Install v0.3.0 [FAILS to find setuptools>=40.8.0) 
   $ git checkout v0.3.0
   $ pip install --no-deps -e .
   
   # Install v0.2.0 [SUCCEES]
   $ git checkout v0.2.0
   $ pip install --no-deps -e .
   

   Running pip cache list | grep setuptools gives me nothing. It seems the failures I'm getting is because I don't have setuptools cached.

   It seems there are two different issues here.

   1. installation failure due to missing setuptools caches
   2. incorrect package version (e.g., pygmt-0.0.0)

   @maxrjones Are you talking about the first one?

   Yes, I was talking about the first one. #2097 (comment) makes sense as an explanation, as I had setuptools installed in my environment.

   I'm inclined to close the issue to reduce the number of our opened issues, mainly because:

   • The need for offline installation is rare
   • It's very likely that setuptools_scm doesn't allow offline installation and there is very little we can do.

   Closing the issue but feel free to reopen it if necessary.
