python3.3 Entry Point not found

[felixgao]

I am trying to make ipython work with my new python3.3 installation through brew.
OSX: 10.8.1

 #!/usr/local/Cellar/python3/3.3.0/bin/python3
 # EASY-INSTALL-ENTRY-SCRIPT: 'ipython==0.13.1','console_scripts','ipython'
 __requires__ = 'ipython==0.13.1'
 import sys
 from pkg_resources import load_entry_point

 sys.exit(
    load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython')()
 )

Traceback (most recent call last):
File "/usr/local/bin/ipython3", line 8, in
load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython')()

how did you install IPython?

[felixgao]

pip3 install ipython

[minrk]

Interesting, It didn't build the script properly. The entry point should be:

load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython3')()

(note ipython3, not ipython)

I just did a test with pip install ipython in a Python 3.3 virtualenv (OS X 10.8.3, though I doubt that is relevant), and it did the right thing. My only thought is to make sure your distribute and pip are up to date, then try reinstalling IPython.

[felixgao]

I changed the script to use ipython3 and

load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython3')()

$ipython3

Cleaning up...

I guess I might be stuck with my python2.7 for a while.

[minrk]

do not install pexpect, it is not compatible with Python 3. Install pexpect-u - a unicode-aware fork of pexpect.

[takluyver]

Or indeed just don't install either - IPython includes a copy of pexpect-u
that it will use if it doesn't find a system copy.

[felixgao]

awesome. thanks for all the help. removing pexpect solved the problem.

[donaldbraman]

Thanks for the tip on pexpect-u. Had the same problem and it worked for me, too.
