在Easy-Ins中确定python版本

Question

我不想在CentOS 5.9上安装“扭曲”模块。默认情况下有Python2.4，由于其他程序依赖性，我无法删除Python2.4。 我已经通过yum install python27安装了python2.7，并通过yum install python-setuptools安装了Easy Install。现在，当我试图用easy_install twisted安装'twisted'时，我得到了一个错误：

如您所见，Easy Install使用python2.4而不是python2.7。它如何强迫它使用python2.7？在

Answer 1

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

如果由于某种原因，easy_install没有为Python 2.7安装，您可以下载并手动安装{a1}。在
