Problems with Linux Python

The following error occurred while using Yum

File "/usr/bin/yum", line 30

Except Keyboardinterrupt, E:

^

Syntaxerror:invalid syntax

This is caused by the upgrade of Python

Vim/usr/bin/yum

Change #!/usr/bin/python2 to #!/usr/bin/python2.6

The CentOS 6.5 default installs only the ReadLine module and does not install the Readline-devel module, so just install it

Yum Install Readline-devel-y

Enter the Python3 source directory, recompile

Make

Make install

Tab Auto-complete

Installing ReadLine

Yum Install readline*-y

Create a Pythonstartup file, place it anywhere, I put it under/usr/local/python3.

# python startup fileimport sysimport readlineimport rlcompleterimport atexitimport os# tab Completionreadline.parse_and _bind (' Tab:complete ') # History filehistfile = Os.path.join (os.environ[' HOME '), '. Pythonhistory ') Try:readline.read_ History_file (histfile) except IOError:passatexit.register (Readline.write_history_file, histfile) del os, Histfile, ReadLine, Rlcompleter

Adding environment variables in ~/.bash_profile

Export Pythonstartup=/usr/local/python3/pythonstartup

Refresh Configuration
