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

Question

我在安装 Twisted 时也遇到了同样的错误。

这是版本信息:

• Django :1.9
• Python:3.5
• 尝试安装最新版本的 Django-channels
• 使用的命令:pip installchannels

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。

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 上没有适用于 Twisted 的 Python 3.5 轮(目前)。所以你需要一个可用的 C 编译器。

关注these instructions for installing VS2015获得一个可用的 C 编译器，以便 Twisted 可以构建必要的扩展模块并成功安装。
