我不想在 CentOS 5.9 上安装 'twisted' 模块。默认情况下有 python 2.4 ，由于其他程序依赖关系，我无法删除 python 2.4 。我已经安装了 Python 2.7yum install python27并安装了 Easy Install yum install python-setuptools。现在，当我尝试安装 'twisted' 时easy_install twisted出现此错误：

如您所见，Easy Install 使用 python 2.4 而不是 python 2.7 。它如何强制它使用 python 2.7 ？

您可以通过键入 eg 手动使用您想要的任何 Python 版本Python2.7 <script>。尝试执行python2.7 -m easy_install twisted。

如果由于某种原因easy_install没有安装，您可以在此处Python 2.7手动下载并安装。
