Error installing virt-manager

[q5616417]

Hi, when I try to install virt-manager, this error occurs:

==> python3 -c import setuptools... --no-user-cfg install --prefix=/private/tmp/virt-manager--homebrew-virtualenv-20200304-452-izouvx/target --install-scripts=/private/tmp/virt-manager--homebrew-virtual ==> python3 -s /private/tmp/virt-manager--homebrew-virtualenv-20200304-452-izouvx/target/bin/virtualenv -p python3 /usr/local/Cellar/virt-manager/2.2.1_3/libexec Error: An exception occurred within a child process: NameError: undefined local variable or method `python' for #Language::Python::Virtualenv::Virtualenv:0x00007ff56ca86088 Did you mean? @python

Command Line Tools are 11.4 beta 3 XCode 11.3.1 MacOS 10.15.3

Do you have an idea what I could do to make virt-manager install?

Best regards

Thomas

@q5616417 check to make sure your virtual environment is not activated when installing virt-manager.
