Common Error Resolution:

1. If you compile Python, the following problems occur

/usr/bin/ld:cannot find-lpython2.7
Collect2:ld returned 1 exit status
Error:command ' gcc ' failed with exit status 1

Use the following procedure to process:

A. Check and install the Python-devel package

# yum-y Install Python-devel

B. Establish a soft connection to the Libpython2.7.so library file under/usr/lib

Execute under 32-bit server

# ln-s/usr/local/python2.7/lib/libpython2.7.so/usr/lib/libpython2.7.so

Execute under 64-bit server

# ln-s/usr/local/python2.7/lib/libpython2.7.so/usr/lib64/libpython2.7.so

C. Check to see if the/etc/ld.so.conf contains/usr/local/python2.7/lib

#vi/etc/ld.so.conf Add/usr/local/python2.7/lib
#/sbin/ldconfig

2. If Python upgrades to 2.7 after Yum unusable, the error is no module named Yum, follow these steps to change the Python version used by Yum to an older version:

Open Yum Execution file

# Vim/usr/bin/yum

Change the first line of #!/usr/bin/python to the original Python version of the backup, as follows:

#!/usr/bin/python_old
