“点安装”错误：InsecurePlatformWarning

Question

每当我尝试通过终端（最近是 Yelp API Python 包）使用 pip install 时，我都会得到：

Macintosh:~ Ryan$ pip install yelp
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pip-7.1.0-py2.6.egg/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.

当我用sudo 尝试它时，我得到了类似的东西，只是包括：

目录“/Users/Ryan/Library/Caches/pip/http”或其父目录不归当前用户所有，缓存已被禁用。请检查该目录的权限和所有者。如果使用 sudo 执行 pip，您可能需要 sudo 的 -H 标志。

当我查找 InsecurePlatformWarning 时，它告诉我升级 Python（我已经完成了），但是当我运行 pip install --upgrade ndg-httpsclient 时，我得到同样的 InsecurePlatformWarning 错误。

如果我尝试使用pip install --upgrade pip 升级pip（因为终端还说“您使用的是 pip 版本 7.1.2，但是版本 8.1.2 可用。”），我也会收到错误：

异常：回溯（最近一次调用最后一次）：文件 "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pip-7.1.0-py2.6.egg/pip/basecommand.py", 第 223 行，主要 status = self.run(options, args) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pip-7.1.0-py2.6.egg/pip/commands /安装.py", 第 282 行，运行中 requirements_set.prepare_files(finder) 文件“/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pip-7.1.0-py2.6.egg/pip/req/req_set.py ",

等等

对我来说，问题似乎是 pip 仍在使用 Python 2.6，但即使我已经升级，我也无法让 pip 识别它。例如：

Macintosh:~ Ryan$ python -V
Python 2.6.4
Macintosh:~ Ryan$ python2.7 -V
Python 2.7.10
Macintosh:~ Ryan$ python3.4 -V
Python 3.4.1
Macintosh:~ Ryan$ python3.5 -V
Python 3.5.1

我是 Python 新手，但我更喜欢 2 而不是 3。关于如何解决所有这些问题有什么建议吗？

Macintosh:~ Ryan$ pip -V
pip 7.1.0 from /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pip-7.1.0-py2.6.egg (python 2.6)

感谢聊天中的I'L'I -- 我必须在这里更改我的权限sudo chown -R Ryan "/Users/Ryan/Library/Caches/pip/http'' 然后重新安装get-pip.py。
