What permission for /usr/local/bin ??

[robert rottermann]

Hi there,

I updated to Ubuntu 19.04.

Now I get a permission error when I try to install virtualenvwrapper:

Exception:
Traceback (most recent call last):
   File 
"/usr/lib/python2.7/dist-packages/pip/_internal/cli/base_command.py",

     status = self.run(options, args)
   File

     shutil.move(old, new)

     os.unlink(src)
OSError: [Errno 13] Permission denied: '/usr/local/bin/virtualenvwrapper.sh'


Now my question: what is the recommended access settings for 
/usr/local/bin/ ?

thanks
