我的服务器上有两个python版本，即2.4和2.7。它正在运行RHEL 5.8

我的服务器上已经安装了pip和easy_安装

当我尝试使用easy_install或pip安装ipython时，它会给我一个错误，这在python2.4中可能不支持

我想对pip和easy_安装都使用Python2.7，因为我想使用两者的最新版本

我应该怎么做才能让pip和easy_安装使用python 2.7。系统默认安装Python2.4，我希望保留它

Python 2.7安装在另一个位置

以下是便于安装和pip的回溯。两者最终都会出现相同的错误。感谢您的任何帮助

一种方法是：

  • 在文本编辑器中打开pip/easy_安装

  • 检查顶行，应该是

    #！/usr/bin/python

  • 将其更改为#！path/to/python2.7

    • 如果您想通过下载.dmg轻松安装iPython、SciPy、MatPlotLib等，可以在此处尝试：

    或者，如果您有学术电子邮件地址：

    sudo/location/to/python2.7/path/to/pip安装ipython

    如果您有最新版本的pip，还可以尝试
    sudo pip-2.7安装ipython

    您应该检查一下

    您还可以考虑通过<代码> > VirtualEnv和 VirtualEnvRePraser-<代码>使用虚拟环境来管理您的Python应该使用哪个版本。

    从错误消息中，OP是在某些Linux发行版上，而不是MAC。
