virtualenv 中的 ctypes 在 system32 中找不到 dll

Question

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

编辑

python 3.5 出现错误！库在 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)

    self._handle = _dlopen(self._name, mode)
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

是的。你说得对 . Somehow I've got only part of runtime installed. Installing https://www.microsoft.com/en-us/download/details.aspx?id=48145 解决了问题。
