Python 3.x 为什么它会在抛出错误后进入虚拟环境？

每当我尝试在虚拟环境中运行我编写的代码时，它都会执行这种我无法修复的异常操作。代码很简单：

import requests

r = requests.get("https://xkcd.com/353/")
print(dir(r))

顺便说一下，我已经安装了请求模块。这就是信息的含义：

$ python -u "c:\Users\Emperor Shridu\Desktop\my project\requestslibr.py"
Traceback (most recent call last):

    import requests
