Installation and use of Linux under Easy_install

The Easy_install tool in Python works very well, and it acts like a pear in PHP, or a gem in Ruby, or a cpan in Perl.

1.easy_install Installation

If you want to use the Easy_install tool, you need to install Setuptools first, but the cool way is to use the ez_setup.py script:
Execute the following command:

12	shell#  wget -q http://peak.telecommunity.com/dist/ez_setup.pyshell#  python ez_setup.py

After installation, it is best to ensure that the directory where the Easy_install is located has been added to the PATH environment variable:

Linux:/usr/local/bin

For example, to install the Python MySQL support, you can execute the following command, the system will automatically find the relevant package in the PYPI Web site list:

1	easy_install MySQL-python

With the Easy_install installation software, the relevant installation information is saved to the Easy-install.pth file, which is similar to the following path:

Linux:/usr/local/lib/python25/site-packages/easy-install.pth

If you want to delete a package installed through Easy_install, say: Mysql-python, you can execute the command:

1	easy_install -m MySQL-python

This action will erase the Mysql-python information from the Easy-install.pth file, and the remaining egg files can be deleted manually.
