'PyDevTerminalInteractiveShell' object has no attribute 'has_readline'

Question

I am using Pycharm 2016.1 on CentOS7 and I am testing "Show command line afterwards" and I got this Probl

Answer 1

This PyCharm issue occurs because of changes the the iPython api with iPython version 5. Until Jetbrains fix this, reverting to an earlier version of iPython (version 4) will correct this. As @chenfei has discovered, this can be done through pip:

$ pip uninstall ipython
$ pip install ipython==4.2.0

Edit

And if you can't wait that long, Jetbrains have released a patch

Final Edit

This issue has been fixed in PyCharm 2016.2

Answer 2

The way I managed to solve this problem without downgrading iPython was:

1 - Download the following patch:

https://youtrack.jetbrains.com/_persistent/pycharm_ipython5_fix.patch?file=74-327779&c=true

2 - Inside PyCharm, create a new project located on:

<PyCharm installation folder>/helpers/pydev/_pydev_bundle/

Pycharm will prompt you to import the files on that folder, accept.

3 - Click on VCS and choose Apply Patch

4 - Choose the file you've downloaded on step 1.

5 - The Apply Patch window will open, click OK

6 - Restart PyCharm

The Python Console should be now working inside PyCharm

PS: You can delete the project folder (.idea) you've created on Step 2
