使用easy_install安装和卸载python扩展包

安装

以安装Twisted举例

easy_install Twisted

如果出现下面的提示，是因为权限问题，这时需要执行下面的命令

sudo easy_install Twisted

附：权限问题报错

error: can’t create or remove files in install directory

The following error occurred while trying to add or remove files in the

installation directory:

[Errno 13] Permission denied: ‘/usr/local/lib/python2.7/dist-packages/test-easy-install-28745.write-test’

The installation directory you specified (via –install-dir, –prefix, or

the distutils default setting) was:

/usr/local/lib/python2.7/dist-packages/

Perhaps your account does not have write access to this directory? If the

installation directory is a system-owned directory, you may need to sign in

as the administrator or “root” account. If you do not have administrative

access to this machine, you may wish to choose a different installation

directory, preferably one that is listed in your PYTHONPATH environment

variable.

For information on other options, you may wish to consult the

documentation at:

https://pythonhosted.org/setuptools/easy_install.html

Please make the appropriate changes for your system and try again.

卸载

以卸载Twisted举例

easy_install -m Twisted

同理，如果权限不够，加sudo

sudo easy_install -m Twisted
