为什么使用 Python easy_install 时会出现“权限被拒绝”错误？

我是 Ubuntu 新手，一直尝试安装 python 的 easy_install，以便在安装 Python 库时不必处理源文件。

我运行了以下命令，它似乎安装了正确的应用程序：

sudo apt-get install python-setuptools

但是，当我运行easy_install sqlalchemy或时easy_install pysqlite3，它不起作用。

我收到以下错误消息：

install_dir /usr/local/lib/python2.6/dist-packages/
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/python2.6/dist-packages/test-easy-install-1674.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib/python2.6/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:

  http://packages.python.org/distribute/easy_install.html

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

答案很简单，只需运行sudo easy_install。

但是，如果出于某种原因你不想这样做，也可以在你的主目录中安装 Python 包。该过程在本文，并涉及修改 PYTHONPATH 环境变量。
