Question

我有一个程序，我非常需要依赖列表，但pip freeze不起作用。我正在运行CentOS 7和Python 2.7.5

该程序在Python 2.4上运行（我在另一个终端上做别名，是的，我确实从该终端尝试了pip freeze）和fortran95。我肯定已经安装了pip。我尝试升级Python2.7，但它说没关系。

pip的错误如下。

[root@localhost rotate6]# pip freeze

Exception:

这是一个已知问题。见https://github.com/pypa/pip/issues/3764

建议尝试将您的pip版本降级为不太严格的版本（有些人认为8.1.0有效），或者卸载有问题的软件包，这似乎是_ipap11helper

在虚拟环境中，安装了centos和pip，我无法运行pip冻结
