Python2.7.12 Development Environment Construction (auto-complete)

First, install the Readline-devel package

Python's compiled installation relies on this package

Yum-y Install Readline-devel

Second, installation Python2.7.12

Python official website (download here):https://www.python.org/

# Tar XF python-2.7.12.tgz

# CD Python-2.7.12

#./configure--prefix=/usr/local/python27

# Make && make install

# ln-sv/usr/local/python27/bin/python2.7/usr/bin/python27

third, add Python auto complement function for VIM editor

1 , download Python auto-complete plugin: pydiction

wget https://github.com/rkulla/pydiction/archive/master.zip

# Unzip-q Master

# MV Pydiction-master Pydiction

# mkdir-p ~/.vim/tools/pydiction

# cp-r Pydiction/after ~/.vim

# CP Pydiction/complete-dict ~/.vim/tools/pydiction

2, ~/.VIM directory structure is as follows:

# Tree ~/.vim

/root/.vim

├──after

│└──ftplugin

│└──python_pydiction.vim

└──tools

└──pydiction

└──complete-dict

3, edit ~/.VIMRC, add the following content

FileType plugin on

Let g:pydiction_location = ' ~/.vim/tools/pydiction/complete-dict '

4, use Vim to edit a py file, test whether successful

The scenario description is configured successfully

Iv. Configuring automatic completion for Python in interactive mode

1./usr/local/python27/lib/python2.7/site-packages add tab.py file in Python installation directory

The tab file contents are as follows:

#!/usr/bin/env python27#python startup fileImportSYSImportReadLineImportRlcompleterImportatexitImportOS#Tab CompletionReadline.parse_and_bind ('Tab:complete')#History FileHistfile = Os.path.join (os.environ['HOME'],'. Pythonhistory')Try: Readline.read_history_file (histfile)exceptIOError:PassAtexit.register (Readline.write_history_file, Histfile)delOS, Histfile, ReadLine, Rlcompleter

2. Add Environment variables:

#vim ~/.BASHRC Add the following:

#for python tab

Export pythonstartup=/usr/local/python27/lib/python2.7/site-packages/tab.py

3. Re-login to the shell for testing:

and shell usage, press TAB to complete, press the TAB key to list all the commands that begin with the input character.
