Changed from execv to execve with empty env dict because bench commands on macOS 10.14.6 PY3.9.0a4 fails with "Error while finding module specification for 'frappe.utils.bench_helper' (ModuleNotFoundError: No module named 'frappe')"
This error has come up in the past too. I'm now suspecting it has
something to do with the current process passing on it's environment
variables to the process that's going to replace it, which causes these
issues.
Note that direct execution of the commands without the bench wrapper
worked fine although via bench failed with the specified error
Due to "WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly."
