Question

我正在尝试安装一些python包，但每次都会遇到这种错误。

The directory '/home/username/.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.

目录＆＃39; /home/username/.cache/pip'或其父目录不归当前用户所有，并且已禁用缓存轮。检查该目录的权限和所有者。如果用sudo执行pip，你可能需要sudo＆＃39; -H标志。

我在这个网站上查了一下，Stack Overflow和所有解决方案都建议安装

轮或

setuptools的但我得到了

要求已经满足

尝试升级python包时会出现同样的问题。

给我这个错误的一些命令是：

sudo pip install -U textblob

我的点子版本是pip 8.1.1

我该怎么办？

Answer 1

按照错误消息的建议尝试，运行：

this.toilets.forEach((toilet) => { console.log(toilet); });

同样值得确保您的pip版本是最新的：

sudo -H pip install -U textblob

或

sudo python -m pip install -U pip

Answer 2

这经常发生在我身上。试试这个：

master

这也适用于其他软件包。

谢谢！
