【问题描述】：

我正在尝试安装 h5py 并执行 sudo

pip3 安装 h5py

我还尝试通过 https://pypi.python.org/pypi/h5py/2.7.0rc2 的轮子安装 h5py

我已经安装了 python 3.5。然后 pip3 崩溃并显示以下输出：

Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 7, in <module>
    from pip import main
  File "/usr/local/lib/python3.5/dist-packages/pip/__init__.py", line 26, in <module>

    orig_path.sort(key=position_in_sys_path)
AttributeError: '_NamespacePath' object has no attribute 'sort'

我在 Ubuntu 16.04.3 LTS 上运行

我不认为 pip3 坏了，因为我之前用 pip3 安装了很多。

我能做什么？

非常感谢。

【解决方案1】：

我会从不开始使用 sudo 进行安装，而是使用 virtualenv。我个人使用virtualenvwrapper。以下在本地对我来说很好。

$ mkvirtualenv bla --python=python3 # Random naming
# Env is activated right away
$ pip3 install h5py
