设置tmp文件夹时遇到问题的Python脚本

试图运行一个Python脚本（从大学网站下载）并不断得到一个错误，其中它无法设置临时目录。我在Windows10下运行这个程序，并尝试过Python 2.6和2.7。无论何时运行代码，都会出现以下错误：

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

回溯（最近一次呼叫最后一次）：
文件“Calign.py”，第116行，在
tmpbase='/tmp/'+os.environ['USER']+'+'u'+str（os.getpid（））
文件“C:\Python27\lib\os.py”，第425行，在\uu getitem中__
返回self.data[key.upper（）]
KeyError:'用户

“Calign”Python脚本中似乎有错误。起初，我认为这只是在翻转斜杠（在路径中使用/where-Windows-uses\），但该修复只会产生更多错误。最终，任何修复脚本的尝试都没有成功——我的Python不够，我也不确定脚本在做什么

我详细地运行了python脚本，如果这样有帮助的话：
