pkg_resources.DistributionNotFound: The 'pathlib2' distribution was not found and is required by ipython

Just before that i followed

 $ git clone --recursive https://github.com/ipython/ipython.git
 $ cd ipython
 $ pip install -e ".[notebook]"

From the link [How to autosave ipython notebook]

http://stackoverflow.com/questions/21517296/how-to-autosave-ipython-notebook

I tried to uninstall and install using apt-get but its still not working and throwing missing distribution error.

I installed pathlib2 though

sudo pip install pathlib2

But again while accessing ipython I see another error

pkg_resources.DistributionNotFound: The 'backports.shutil_get_terminal_size' distribution was not found and is required by ipython

You need install some packages manually as follows:

pip install pathlib2
pip install backports.shutil_get_terminal_size
pip install enum34

You might need to install enum34 also. I needed in Debian Sid. – onur güngör Sep 25 '16 at 12:24
What happens if after doing this you still get the same error message about the pathlib2 not being found/installed? – ComputerScientist Jul 04 '18 at 16:26

For me, I also had to pip install enum34 but otherwise int32bit's answer worked.

pip install pathlib2 backports.shutil_get_terminal_size enum34

I launched the Jupyter notebook from Anaconda "Environments" and the dos Windows open with all the launching packages in issues appearing.

Then I just had to install packages missing and mentioned in this window in your environment one by one. You can retry the same process as many times as needed.
