python - Python 脚本在设置 tmp 文件夹时遇到问题

Question

尝试运行 Python 脚本（从大学网站下载）并不断收到错误，因为它显然无法设置临时目录。我在 Windows 10 下运行它并尝试过 Python 2.6 和 2.7。每当我运行代码时，我都会收到此错误：

Traceback (most recent call last):
  File "Calign.py", line 116, in <module>
    tmpbase = '/tmp/' + os.environ['USER'] + '_' + str(os.getpid())
  File "C:\Python27\lib\os.py", line 425, in __getitem__
    return self.data[key.upper()]
KeyError: 'USER

“Calign”Python 脚本中似乎有错误。最初我认为它只是翻转斜杠（使用 / ，其中 Windows 在路径中使用 \ ），但该修复只会产生更多错误。最终，任何修复脚本的尝试都不起作用——我的 Python 不够用，我不确定脚本在做什么。

如果有帮助，我对 python 脚本进行了详细的运行：
