ImportError: No module named requests
提问by user2476540
回答by TheoretiCAL
Requests is not a built in module (does not come with the default python installation), so you will have to install it:
Requests 不是内置模块（默认 python 安装不附带），因此您必须安装它：
OSX/Linux
操作系统/Linux
Use $ sudo pip install requests(or pip3 install requestsfor python3) if you have pipinstalled. If pip is installed but not in your path you can use python -m pip install requests(or python3 -m pip install requestsfor python3)
如果已安装，请使用$ sudo pip install requests（或pip3 install requests用于 python3） pip。如果 pip 已安装但不在您的路径中，您可以使用python -m pip install requests（或python3 -m pip install requests用于 python3）
Alternatively you can also use sudo easy_install -U requestsif you have easy_installinstalled.
或者，sudo easy_install -U requests如果您已经easy_install安装，您也可以使用。
Alternatively you can use your systems package manager:
或者，您可以使用系统包管理器：
For centos: yum install python-requestsFor Ubuntu: apt-get install python-requests
对于 centos：yum install python-requests对于 Ubuntu：apt-get install python-requests
Windows
视窗
Use pip install requests(or pip3 install requestsfor python3) if you have pipinstalled and Pip.exe added to the Path Environment Variable. If pip is installed but not in your path you can use python -m pip install requests(or python3 -m pip install requestsfor python3)
如果您已安装并将 Pip.exe 添加到路径环境变量中，请使用pip install requests（或pip3 install requests用于 python3） pip。如果 pip 已安装但不在您的路径中，您可以使用python -m pip install requests（或python3 -m pip install requests用于 python3）
Alternatively from a cmd prompt, use > Path\easy_install.exe requests, where Pathis your Python*\Scriptsfolder, if it was installed. (For example: C:\Python32\Scripts)
或者，在 cmd 提示符下，使用> Path\easy_install.exe requests，Path您的Python*\Scripts文件夹在哪里（如果已安装）。（例如：C:\Python32\Scripts）
If you manually want to add a library to a windows machine, you can download the compressed library, uncompress it, and then place it into the Lib\site-packagesfolder of your python path. (For example: C:\Python27\Lib\site-packages)
如果你想手动添加一个库到windows机器，你可以下载压缩库，解压，然后放到Lib\site-packages你的python路径的文件夹中。（例如：C:\Python27\Lib\site-packages）
From Source (Universal)
从源（通用）
For any missing library, the source is usually available at https://pypi.python.org/pypi/. You can download requests here: https://pypi.python.org/pypi/requests
对于任何缺失的库，源通常可从https://pypi.python.org/pypi/ 获得。你可以在这里下载请求：https: //pypi.python.org/pypi/requests
On mac osx and windows, after downloading the source zip, uncompress it and from the termiminal/cmd run python setup.py installfrom the uncompressed dir.
在 mac osx 和 windows 上，下载源 zip 后，将其解压缩，然后从终端/cmdpython setup.py install从未压缩的目录中运行。

I had the same issue, so I copied the folder named "requests" from https://pypi.python.org/pypi/requests#downloadsrequests downloadto "/Library/Python/2.7/site-packages". Now when you use: import requests, it should work fine.
我遇到了同样的问题，所以我将名为“requests”的文件夹从https://pypi.python.org/pypi/requests#downloads requests download复制到“/Library/Python/2.7/site-packages”。现在，当您使用：导入请求时，它应该可以正常工作。

For windows just give path as cd and path to the "Scripts" of python and then execute the command easy_install.exerequests.Then try import requests...
对于 Windows，只需将路径作为 cd 和路径提供给 python 的“脚本”，然后执行命令easy_install.exe请求。然后尝试导入请求...

you can also use pip install on windows by first locating the pip3.exe file in the directory: say for me==> cd c:\python34\scripts then run ==> pip3 install requests
您还可以通过首先在目录中找到 pip3.exe 文件来在 Windows 上使用 pip install： 对我说==> cd c:\python34\scripts 然后运行 ==> pip3 install requests
