To solve this, upgrade your pip and rerun the install.py
python3 -m pip install --upgrade pip

I have de same problem, it is not letting me install

any idea how to solve it? I have already tried updating pip, setuptools…

There’s a lot of discussion about this on the internet. It’s usually a version incompatibility, but the few times I’ve run into it it took a lot of debugging.

did you try the above command? what was the output?

yes i have tried

and its not working

Any solution of it?

Hey there, run this command as root to tell pip to upgrade itself

pip3 install --upgrade pip

Then go back to your frappe user and try to install again

@Jibril
Thanks but it’s not working. Im running VB ubuntu 18.04 >>

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.
