Virtualenv Permission denied when trying python setup.py install

I want to use virtualenv with Python 3 on Ubuntu 18.04. Specifically, I'm using Python 3.6.6 and virtualenv 16.0.0.

1. I installed virtualenv with sudo as suggested in the answers here: sudo pip3 install --upgrade virtualenv

2. I created a new virtualenv using python3 -m virtualenv venv. And activated it as usual: source venv/bin/activate.

3. When I try to install my Python project with python setup.py install I get the following error message:

 running install running bdist_egg running egg_info error: [Errno 13] Permission denied 

If I use sudo to create the virtualenv in step 2, then I get a different error message in step 3:

error: can't create or remove files in install directory The following error occurred while trying to add or remove files in the installation directory: [Errno 13] Permission denied: '/home/stefan/git-repos/tng-sdk-project/venv/lib/python3.6/site-packages/test-easy-install-3769.write-test' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /home/stefan/git-repos/tng-sdk-project/venv/lib/python3.6/site-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable. For information on other options, you may wish to consult the documentation at: Please make the appropriate changes for your system and try again. 

I've been googling and trying stuff for hours now and I can't get it to work properly. It seems like whatever I try leads to more, new errors... Any ideas?

Well, sudo python setup.py install works inside the virtualenv, but this can't be the solution.

Most probably used sudo for some instructions that create some folder with root ownership.

1. Deactivate the virtual env.

2. Try fix owner recursively:

   sudo chown -R stefan:stefan /home/stefan/git-repos/tng-sdk-project/ 

3. Activate virtual env and test it.
