在cifs目录中的`stack build`期间,'cabal copy'失败了

Question

我正在遵循这些指示.我成功了stack new,stack setup但stack build失败了.

我发现一个git问题,这可能是由于cabal文件中列出的额外文件,但删除它们并没有解决问题(我只是使用new-template没有任何更改).我在Ubuntu 14.04上并使用脚本安装了堆栈.还有什么我可以研究一下吗？

看来这可能是由于我试图在cifs目录中构建.我能做些什么来处理这件事吗？

One possible cause of this issue is:
* No module named "Main". The 'main-is' source file should usually have a header indicating that it's a 'Main' module.

看起来该问题是由项目所在文件夹的深度引起的（Windows 10，x64）。从深度超过某个阈值的那一刻起，就会出现所描述的错误。因此，请尝试将项目文件夹在目录树中向上移动。
