Seeing escape characters when pressing the arrow keys in python shell
On OS X, I have different problem.
When I using system python shell, the keys is no problem, but problem in virtualenv. I'd try to reinstall/upgrade virtualenv/readline and nothing fixed.
While I try to import readline in problem python shell, get this error message:
ImportError: dlopen(/Users/raptor/.virtualenvs/bottle/lib/python2.7/lib-dynload/readline.so, 2): > Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib
Referenced from: /Users/raptor/.virtualenvs/bottle/lib/python2.7/lib-dynload/readline.so
Reason: image not foundCause there is /usr/local/opt/readline/lib/libreadline.7.dylib but not libreadline.6.dylib, so I make a symbol link:
ln libreadline.7.dylib libreadline.6.dylib
Problem has been solved!
这个问题第一次被问到是 7年前，常问常新。
