我使用的是Ubuntu 16.04，所以我使用sudo pip install numpy toml但是：

The directory '/home/nando/.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.

显然我已经满足了要求，但是当我运行第一个命令时，我仍然收到相同的错误消息。我该如何解决这个问题？

显然问题是我有python 2和3，我在3中安装了toml。运行：

sudo -H pip2 install toml

为我解决了这个问题

Answer 2

我通过使用pip3安装toml解决了该问题
