加载中…pip安装模块时可能遇到的问题
(2016-01-13 22:42:20)| 分类： python |
（1）使用命令：sudo pip install
numpy时，可能遇到：
The directory
'/Users/huangqizhi/Library/Caches/pip' or its parent directory is
not owned by the current user and caching wheels has been disabled.
check the permissions and owner of that directory. If executing pip
with sudo, you may want sudo's -H flag.
说得很清楚，是pip目录的属主不是sudo的root用户。如果必须用sudo
pip，更改pip目录属主即可：
sudo chown
root
（2）pip安装时，可能遇到：
/Library/Python/2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90:
InsecurePlatformWarning: A true SSLContext object is not available.
This prevents urllib3 from configuring SSL appropriately and may
cause certain SSL connections to fail. For more information, see
https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
解决方法：安装requests，注意后面带[security]：
pip install
requests[security]
