根据@Ab 的评论,它可以工作。

但是为什么我需要导入 sys ?

您可以运行import sys ; sys.path并查看是否c:\python27\lib\site-packages\在您的路径列表中。如果是,那么再次尝试运行from xlwt import easyxf

你显然没有xlwt安装,或者 Python 不知道你安装了。

尝试运行pip install xlwt

您还可以查看代码的物理xlwt位置,然后将该文件目录添加到您的目录中,PYTHONPATH以便 Python 知道在那里查找模块。

这可能是因为您正在从virtualenv尚未xlwt安装的代码中运行代码。
