So why is this sort of error happening while running the python file?

One possible reason is that you have multiple python executables in your environment, for example 2.6.x, 2.7.x or virtaulenv. You might install the package into one of them and run your script with another.
一种可能的原因是您的环境中有多个 python 可执行文件，例如 2.6.x、2.7.x 或 virtaulenv。您可以将软件包安装到其中一个中并使用另一个运行您的脚本。
Type python in the prompt, and press the tab key to see what versions of Python in your environment.
在提示中键入 python，然后按 Tab 键以查看您的环境中的 Python 版本。

I had this error before when I was executing a python3 script, after this:
我之前在执行 python3 脚本时遇到过这个错误，在此之后：
sudo pip3 install requests
sudo pip3 install requests
the problem solved, If you are using python3, give a shot.
问题解决了，如果您使用的是python3，请试一试。

In Windows it worked for me only after trying the following: 1. Open cmd inside the folder where "requests" is unpacked. (CTRL+SHIFT+right mouse click, choose the appropriate popup menu item) 2. (Here is the path to your pip3.exe)\pip3.exe install requests Done
在 Windows 中，它仅在尝试以下操作后才对我有用： 1. 在解压缩“请求”的文件夹中打开 cmd。(CTRL+SHIFT+鼠标右键，选择合适的弹出菜单项) 2. (这里是你的pip3.exe的路径)\pip3.exe install requests Done

if it works when you do :
如果它在你这样做时有效：
python
>>> import requests
then it might be a mismatch between a previous version of python on your computer and the one you are trying to use
那么它可能是您计算机上以前版本的 python 与您尝试使用的版本不匹配
in that case : check the location of your working python:
在这种情况下：检查您的工作 python 的位置：
which pythonAnd get sure it is matching the first line in your python code
which python并确保它与您的 python 代码中的第一行匹配
#!<path_from_which_python_command>

Opening CMD in the location of the already installed request folder and running "pip install requests" worked for me. I am using two different versions of Python.
在已安装的请求文件夹的位置打开 CMD 并运行“pip install requests”对我有用。我正在使用两个不同版本的 Python。
I think this works because requests is now installed outside my virtual environment. Haven't checked but just thought I'd write this in, in case anyone else is going crazy searching on Google.
我认为这是有效的，因为请求现在安装在我的虚拟环境之外。还没有检查，但只是想我会写这个，以防其他人在谷歌上疯狂搜索。
