在 Windows 上的 Python 3.5 上安装 Django-channels 时出错

Question

我在安装 Twisted 时也遇到同样的错误。

这是版本信息：

Django：1.9
Python : 3.5
正在尝试安装最新版本 Django-channels
使用的命令：pip install channels

错误：

running build_ext
building 'twisted.test.raiser' extension error: [WinError 2] The system cannot find the file specified

（几乎）完整的错误消息

我不知道我错过了什么，请有人帮助我，谢谢。

Answer 1

您需要一个可用的 C 编译器才能在未提供轮子的平台上安装 Twisted。 PyPI 上没有 Python 3.5 wheel for Twisted（此时）。所以你需要一个工作的 C 编译器。

按照 these instructions for installing VS2015 获取工作的 C 编译器，以便 Twisted 可以构建必要的扩展模块并成功安装。

Answer 2

我遇到了类似的问题...我只能通过下载 Visual Studio 构建工具并安装 Visual C++ 构建工具、Windows 10 SDK 和 VC++ 2015.3 v14

Answer 3

问题不在于是否需要 Visual C++ 14.0 或其他任何东西。它与 Twisted 的安装有关。一起尝试数周后，我能够解决这个问题。要安装正确版本的 Twisted，请访问此 link。（在类似问题的答案中发现了这一点，我不确定作者是否给予了应有的学分）。上面提到的 link 显示了 Twisted 的几个版本。您应该下载与您的 python 版本相对应的版本。例如，如果您的 python 版本是 3.5，您应该继续下载 cp35m-win32.whl（仅适用于 Windows）等等。此外，打开命令提示符，转到下载的路径激活您的虚拟环境并 pip 安装下载的文件。这将解决您的问题。

Answer 4

需要 Microsoft Visual C++。使用“Microsoft Visual C++ 构建工具”获取它：https://visualstudio.microsoft.com/downloads/
