[Distutils] pip3 subversion user

[Weatherby,Gerard]

Apologies in advance if this is the wrong list for the question; if so,
a pointer to the correct one would be appreciated.

I'm trying to user the subversion option of pip3 to install a package; I
can use
sudo pip3 install svn+https://path_to_code , but this does not work
because our subversion repository requires a subversion user name, and I
don' t know to pass it through pip3 to subversion.

Tried:
sudo pip3 install --user gweatherby svn+https://path_to_code, but it
still prompted for "root" password.
