Python 3.6.1 crashed after readline module installed
Question:
I’ve compiled and installed Python 3.6.1 from source code, and run sudo pip3 install readline to install the readline module. But when I start the Python shell, it crashes whatever I enter:
Python 3.6.1 (default, Mar 25 2017, 13:40:56)

What’s the matter here? I’m using Ubuntu 16.04.
Answers:
Same problem.
Solve it by using gcc-4.7 for compilation python source instead gcc-5.4
As far as I can tell, this is the same problem encountered below. I’ve posted the answer that worked for me, there.
Try pip install gnureadline instead. And remove readline: pip uninstall readline.
As explained by the gnureadline package page on pypi.org:
Some platforms, such as macOS, do not ship with GNU readline installed
This module [bundles] the standard Python readline module with the GNU readline source code, which is compiled and statically linked to it. The end result is a package which is simple to install and requires no extra shared libraries.
So the gnureadline package comes with the required code compiled and linked whereas the builtin python readline library relies on GNU readline (or an alternative) to be installed on the system already.
Mac:
pip install readline
Windows:
pip install pyreadline
Unix:
pip install gnureadline
I’ve compiled and installed Python 3.6.1 from source code, and run sudo pip3 install readline to install the readline module. But when I start the Python shell, it crashes whatever I enter:

What’s the matter here? I’m using Ubuntu 16.04.
Same problem.
Solve it by using gcc-4.7 for compilation python source instead gcc-5.4
As far as I can tell, this is the same problem encountered below. I’ve posted the answer that worked for me, there.
Try pip install gnureadline instead. And remove readline: pip uninstall readline.
As explained by the gnureadline package page on pypi.org:
Some platforms, such as macOS, do not ship with GNU readline installed
This module [bundles] the standard Python readline module with the GNU readline source code, which is compiled and statically linked to it. The end result is a package which is simple to install and requires no extra shared libraries.
So the gnureadline package comes with the required code compiled and linked whereas the builtin python readline library relies on GNU readline (or an alternative) to be installed on the system already.
Mac:
pip install readline
Windows:
pip install pyreadline
Unix:
pip install gnureadline
