Python + Pycharm = pbm安裝lxml＆cairosvg'不屬於當前用戶的目錄'

Question

使用Pycharm，我試圖安裝Pygall，它需要lxml和cairosvg。 我創建了一個 'requirements.txt' 文件列出模塊：

執行的命令：

pip install lxml 

錯誤：

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. 

輸出：

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我求婚解決方案：

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'. 

我試圖從命令行安裝，但後來我得到一個「已經滿足」消息：

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

所以我想我不得不在屋裏Pycharm改變的用戶...我怎麼能這樣做？在彈出窗口中，我試圖通過我的第一個名字（我用作sudo帳戶）更改我的全名（第一個+姓氏），但我得到了同樣的錯誤...

sudo pip install lxml應該能夠移除任何Linux上的權限問題

如果您在Windows計算機上，請右鍵單擊命令提示符並選擇'以管理員身份運行'，然後執行pip install命令。
