描述

用python开发了一个opc client应用，调试没有问题后，使用pyinstaller打包成exe，测试exe运行也没有问题，正常使用。
在某次重装win10系统后，在此运行exe就开始报错了，详细内容如下：

ImportError: No module named path
----------------------------------------

实在是搞不懂是为啥，path不是os模块中的吗，python自带啊，怎么还会出错，查了一天也没弄明白咋回事。
后来实在没办法了，将程序重新打包成了文件夹的形式，再运行就没有问题了。

总结

1. 和windows环境可能有关系，因为同一个程序有的电脑可以运行，而且出问题的这台电脑之前也可以运行，但是重装系统之后就开始报错了。难道重装系统之后环境中缺少了某个依赖？
2. 和pyinstaller的打包有关系，打包成文件夹就没有问题，打包成exe就有问题，可能打包成exe的时候有些依赖没打包进去，但是我不指定是哪出了问题。
3. 实在搞不懂，大家有什么思路希望不吝赐教。
