The directory '/home/pengjiayou/.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.

我是保留 /home 從 14.04 升級到 16.04 的。
嘗試過 chown -R 改 ~/.cache/pip 和 ~/.cache/pip/http 甚至 ~/.cache 的權限，仍然搞不定。
求大神幫忙
