I am trying to install jupyter on mac, I understand that the mac comes with python version installed But i also installed brew and installed python through brew.
When i check python location i get:
which python
/usr/bin/python
When i check pip location i get:
which pip
/usr/local/bin/pip
When i try to install jupyter:
pip install install
after a long installation it tried to remove python package that it want's to upgrade
And fails:
On trying to uninstall dateutil.
I think its the mac packages.
I tried with sudo, no change.
As far as i can understand it because the files are immutable.
Tried to remove the immutable with:
chflags uchg.
No change.
I also tried to work with virtual env, using:
sudo pip install virtualenvwrapper.
But that pip tries to uninstall another python folder.
Any suggestions?
Thanks
UPDATE:
The brew seems to create links from python2. to python2
And the same for python3.
I tried to create the link myself, It worked and i was manage to install the package i wanted. But its not a good solution,
The all point of brew is to manage this things for me, next time i will upgrade python it will break.
Any suggestions why? could it be because the brew installed two python version on my laptop?
RESOLVED:
Found the answer, thanks to @tdube question i went and looked what brew guys did to python and found this thread from Jan 17.
I turns out that they changed the behavior or installing python.
No you don't have simply python any more.
You have python2 and python3.
No more simply pip, now you have pip2 and pip3.
That is a major change from the default behavior of how people use python Especially that mac comes with a default python
so now you have python that is /usr/bin/python python2 that is /usr/local/bin/python2 python3 that is /usr/local/bin/python3
this is the fix, the brew guys suggest ( you can see it when running brew info python ):
==> Caveats
This formula installs a python2 executable to /usr/local/bin.
If you wish to have this formula's python executable in your PATH then add
the following to ~/.zshrc:
export PATH="/usr/local/opt/python/libexec/bin:$PATH"
Pip and setuptools have been installed. To update them
pip2 install --upgrade pip setuptools
You can install Python packages with
pip2 install <package>
They will install into the site-package directory
/usr/local/lib/python2.7/site-packages
