Solving the Yum failure problem

# Vim/usr/bin/yum
#!/usr/bin/python
Change into
#!/usr/bin/python2.4

-------------------------------

At the beginning of the installation of the python2.7.3, after successful installation, run Django Error:

Importerror:no module named _sqlite3

Follow the universal solutions on the Web:

Yum Install Sqlite-devel

and re-installed the python2.7.3, no use--prefix

But still did not solve this problem, always can not find python-2.7.3/lib/python2.7/lib-dynload/_sqlite3.so.

Personal suspicion is the version of Python 2.7.3.

So the installation of python2.7.8, still did not solve the problem, but there are python-2.7.8/lib/python2.7/lib-dynload/_sqlite3.so.

validation, import sys

Print Sys.path

See the referenced path is the path under/usr/local/lib, summed up the following point of view, if/usr/local/lib under Python, the system will automatically use this Python, Instead of using Python from the directory you--prefix installed to, you run python-v after you've built a soft connection to be the result.

Import Sqlite3 works correctly after removing all previously installed Python under/usr/local/.
