Temporary fix for osx pyenv python not using arrow keys

TL;DR

Since python tries to read libreadline.6.dylib, I put it in a compatible symbolic link with another name.

cd $(brew --prefix readline)/lib
ln -s libreadline.dylib libreadline.6.dylib

environment

• OSX Terminal.app
• Xcode 8.0
• Homebrew
  • pyenv 1.0.2
  • zsh 5.2

Event and history

The arrow keys die in the virtualenv + pyenv python environment that I put in with brew. python There are some arrow keys and history problems.

Try pip install readline and ʻimport readline`

ImportError: dlopen(/usr/local/var/pyenv/versions/3.5.2/lib/python3.5/lib-dynload/readline.cpython-35m-darwin.so, 2): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib

I wonder if there is libreadline.6.dylib

/usr/local/opt/readline/lib

libhistory.7.0.dylib
libhistory.7.dylib@
libhistory.a
libhistory.dylib@
libreadline.7.0.dylib
libreadline.7.dylib@
libreadline.a
libreadline.dylib@

There is no.

It's also a hassle to find and reinsert the hash of fomula when it was readline 6.x. It's not important, and a bandage with a link.

cd $(brew --prefix readline)/lib
ln -s libreadline.dylib libreadline.6.dylib

Solution (looking at the person who is rushing)
