Python pip install h5py 遇到 TypeError : unsupported operand type(s) for -=: 'Retry' and 'int'

Question

我想在 ubuntu 16.04 LTS 上使用 Python 2.7.12 安装 h5py 模块，但是我遇到了以下问题。下面是回溯。而且我在中国大陆，有很好的防火墙，这有什么关系吗？它？有谁知道如何解决这个问题？谢谢。 我使用命令行:

pip install h5py
Collecting h5py

当我在命令行中添加sudo时，错误提示有所不同。

sudo pip inatall h5py
The directory '/home/yangyong/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

我想我已经解决了我的问题。我在ubuntu 16.04上安装了anaconda，但是没有设置路径。现在我添加了PATH=$PATH:$HOME/anaconda2/bin到.bashrc。然后 anaconda 就可以正常工作了。因为anaconda已经包含了h5py模块。
