python - 在 python 中导入请求模块在 OS X 上不起作用

Question

我的系统上安装了请求模块。

pip install requests

现在我正在尝试在 rpel 中导入请求

import requests

失败并出现以下错误

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named requests

我找到了这个问题的答案here , 但它没有说明在同一目录中有 python 2.x。

我的终端输出是:

MacBook-Pro:~ tanmaybaranwal$ which python

/usr/bin/python

MacBook-Pro:~ tanmaybaranwal$ which python2.6

/usr/bin/python2.6

MacBook-Pro:~ tanmaybaranwal$ which pip

/usr/local/bin/pip

列出 PIP 模块也没有任何 requests 模块。

为确保您使用正确的 python 通过 pip 安装某些东西，您可以通过 -m 运行它

$ python -m pip install --user requests

(如果您省略 --user 标志，那么您可能需要 root 权限)
