使用 Pycharm，我正在尝试安装 Pygall，它需要 lxml 和 cairosvg。我创建了一个“requirements.txt”文件来列出模块：

执行命令：

pip install lxml

错误：

0:425: execution error: The directory '/Users/romain/Library/Caches/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.

输出 ：

You are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Pycharm 给我一个解决方案：

Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at '/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7'.

我尝试从命令行安装，但随后我收到一条“已经满意”的消息：

$ pip install lxml
Requirement already satisfied (use --upgrade to upgrade): lxml in ./anaconda/lib/python2.7/site-packages

所以我想我必须在 Pycharm 中更改用户......我该怎么做？在弹出窗口中，我尝试只用我的名字（我用作 sudo 帐户）更改我的全名（名字 + 姓氏），但我得到了同样的错误......

sudo pip install lxml应该可以解决 Linux 上的任何权限问题

如果您使用的是 Windows 机器，请右键单击命令提示符并选择“以管理员身份运行”，然后执行 pip install 命令。
