PEP 610 support (git packages) can break pip freeze #8139
Description
First of all, great job guys on adding PEP 610 support, this is really awesome !
But, if you install a git package with sudo, it will cause any non root pip freeze to crash
Environment
- pip version: 20.1b1
- Python version: 3.6
- OS: Ubuntu
If you do
sudo pip install git+https://github.com/...Then when you run pip freeze (notice without sudo)
You get the following exception:
ERROR: Exception:
Traceback (most recent call last):

PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.6/site-packages/trains-0.14.1.dist-info/direct_url.json'
As you can see the direct_url.json file is missing the r flag for group / others , which raises the exception.
-rw------- 1 root root 135 Apr 25 23:22 /usr/local/lib/python3.6/site-packages/trains-0.14.1.dist-info/direct_url.json
I tested running chmod 644 on this file, and after that pip freeze works like a charm.
For reference, the top_level.txt file that is next to the direct_url.json has the correct permission
