Can't Install Errbot in Virtual Environment because of `dulwich` installation issue

[areed1192]

Describe the bug I am unable to install errbot in a python 3.9 virtual environment. I get the following output:

Building wheels for collected packages: dulwich
  Building wheel for dulwich (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.
  Rolling back uninstall of dulwich

error: legacy-install-failure

× Encountered error while trying to install package.
╰─> dulwich

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

To Reproduce

pip3 install --user virtualenv
virtualenv --python `which python3` ~/.errbot-ve
~/.errbot-ve/bin/pip install errbot

Expected behavior I expect the package errbot to be installed in the environment.

Environment (please complete the following information):

• Errbot version: errbot-6.1.9
• OS version: Ventura 13.2.1
• Python version: 3.9
• Using a virtual environment: yes
• Using Docker: no

It looks like there's something wrong with the compiler environment, but I can't say for sure, I don't use mac.

@nzlosh Interesting, I'll take a look and see if I can address the issue.

So, it looks like I had to reinstall Xcode. For those who run into this issue just run the following command from your terminal:

xcode-select --install

After that when I went to install errbot in the virtual environment it ran successfully.
