I may have found one further difference of a minor nature. I have my python environments under /usr
rather than /home
or whatever. In order to install to it, I would have to use sudo install pip
. For me, the undesired side effect of sudo install pip
was slightly different than what are widely reported elsewhere: after doing so, I had to run python
with sudo
in order to import any of the sudo
-installed packages. I gave up on that and eventually found I could use sudo conda
to install packages to an environment under /usr
which then imported normally without needing sudo
permission for python
. I even used sudo conda
to fix a broken pip
rather than using sudo pip uninstall pip
or sudo pip --upgrade install pip
.
