What could be wrong? TIA. Two things come to mind. * Check that your alternates configurations are identical on both systems. * check that you are not attempting (directly or indirectly) to use pip to upgrade a package which is provide by a python package installed using the Cygwin setup.exe app. If pip is not installed, you will need to use the Cygwin setup installer for pip. Try using "python -m venv --without-pip VENV" BTW: It is not clear what the current directory is when you run the error command. Was that the complete error message? Was there not also a traceback, possibly with messages before the traceback?
