virtualenv中的ctypes在system32中找不到dll

Question

我正在尝试在virtualenv中使用python模块Shapely，但它无法加载一些具有依赖性的dll。

修改

python 3.5上出现错误！图书馆在3.4

上工作正常

带有二进制文件的轮子：http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

错误：

    "__main__", mod_spec)

OSError: [WinError 126] The specified module could not be found

这表明dll检查器可以在system32目录中找到dll

是。 MSVCP140.dll missing你是对的。不知怎的，我只安装了部分运行时。安装https://www.microsoft.com/en-us/download/details.aspx?id=48145可以解决问题。
