Python 不再起作用-“site”导入失败

Question

周末过后，我电脑上的某些程序已停止正常运行。最重要的是 Scrapy 和 Python，我需要它们来完成特定任务。现在当我运行 Scrapy 时，我收到错误。我尝试卸载并重新安装，但问题仍然存在。请帮忙。我使用的是 Windows 7（我必须使用它）。

C:\Users\abc> scrapy -help
ImportError: No module named site

C:\Users\abc>python
ImportError: No module named site

C:\Users\abc>python -v
