有谁知道如何做到这一点。我用Google搜索了，我能想出的最好的事情就是：
pip install autobahn [twisted]
当我这样做时，我在命令窗口中收到此错误
C:\Users\<User Name>\Desktop>pip install autobahn[twisted]

我不知道如何解决错误
答案 0 :(得分：-1)
转到University of California Irvine's Unofficial Windows Binary for Python Extension Packages并下载Twisted wheel文件。这是简单的方法。困难的方法需要安装编译器（包含在Windows Built Tools中）。
请注意!!!! 对于任何绊到这个帖子的人来说，只有最新的软件包可以通过加州大学欧文分校的网站下载（通常），所以
