link.exe【failed: No such file or directory】

zx490336534 commented 5 years ago

经常会看到 error: command 'E:\\VisualStudio2019\\VC\\Tools\\MSVC\\14.20.27508\\bin\\HostX86\\x64\\link.exe' failed: No such file or directory 的报错，但是这个路径下link.exe是存在的

请再全新的Windows下安装Visual Studio并测试一下？编译器、链接器的问题不是c2py需要考虑的问题哦。

如果这个问题时不时出现，你可以尝试把--setup-use-patches这个参数去掉。这个参数是测试的时候用的，可能会对编译套件的使用产生影响。

我把它的并行去掉了，就不会有这个报错了，感觉是并行的太猛了

nanoric commented 5 years ago

嗯，因为setuptools本身不支持并行编译。这个并行写的并不是非常完美。如果没有其他问题的话，我就把这个issue关闭了哦。

zx490336534 commented 5 years ago

关吧，可以考虑在README.md里面加一下这个可能遇到的问题的解决方法

nanoric commented 5 years ago

嗯，我会整理成问题集锦的。
