IPython command not found Terminal OSX. Pip installed

Question

Using Python 2.7 installed via homebrew. I then used pip to install IPython. So, IPython seems to be installed under:

/usr/local/lib/python2.7/site-packages/

I think this is true because there is a IPython directory and ipython egg.

However, when I type ipython in the terminal I get:

-bash: ipython: command not found

I do not understand why this ONLY happens with IPython and not with python? Also, how do I fix this? What path should I add in .bashrc? And how should I add?

Currently, my .bashrc reads:

PATH=$PATH:/usr/local/bin/

Thanks!

Solution 1

I had this issue too, the following worked for me and seems like a clean simple solution:

pip uninstall ipython

pip install ipython

I'm running mavericks and latest pip

Solution 2

Check IPython whether is installed by below command:

$python -m IPython

If you got this result as above picture.

Then run this command on terminal and add into ~/.bash_profile file

$alias ipython='python -m IPython'

So try run "ipython" again on terminal. It works fine for me.

iPython installed but not found

Solution 3

Create .pydistutils.cfg in your homedir with following content:

[global]
verbose=1

[install]
install-scripts=$HOME/bin

[easy_install]
install-scripts=$HOME/bin

And then: pip install -U --user ipython. Of course $HOME/bin must be in your $PATH. Packages are going to be installed in $HOME/Library/Python, so user only, not system wide.

Solution 4

I use pip3 install ipython is OK.

maybe ipython rely on python3

Solution 5

Try run brew install ipython:

then run xcode-select --install；

run brew install git,

If you got this result as above picture. Refer to enter link description here

At last, run brew install ipython

Hmm....when I do the pip command as you suggested I get: no such option: --user #I added my account name as user, obviously! Any ideas why the command fails?

[nudzo]

pip needs to be installed into homedir too. Run easy_install --user pip, to got one in your $HOME/bin and then --user option will be enabled.

[Rohit]

Wait, when I try EXACTLY the command you suggested I have the following: pip install -U --user ipython Requirement already up-to-date: ipython in /usr/local/lib/python2.7/site-packages Cleaning up...

[Rohit]

OK, I did the following: easy_install --user pip Searching for pip Best match: pip 1.3.1 Processing pip-1.3.1-py2.7.egg Adding pip 1.3.1 to easy-install.pth file Installing pip script to /Users/XXXX/bin Installing pip-2.7 script to /Users/XXXX/bin where XXXX is the username. I also have the .pydistutils.cfg file in my home directory and still ipython command is not recognized.

[nudzo]

The run again: pip install -U --user --force ipython, to get it reinstalled and scripts put in $HOME/bin.

[Rohit]

Yay! That works. Thanks SO MUCH for your patience and perseverance.

Thanks for your answer. I just installed Anaconda and got everything to work.

For some users, doing just pip install ipython might give an access denied error. In that case, you need: sudo pip install ipython

Using pip install -U --user --force ipython worked through.

Found this necessary again on El Capitan; thanks for the detailed instructions.

[braulio]

just had similar issue when updating from Mac OSX Mojave to Catalina and changing to zsh as a standard shell, even in the bash version of it the ipython command was broken, adding alias ipython="python3 -m IPython" to ~/.zshrc fixes it
