Question

我直接从Autobahn获取this example，将其保存为Python脚本，然后将其转移到运行Python 3.5.3的Debian 9发行版。

我试图将此文件转换为可执行的二进制文件。

我将文件保存为defer4.py。然后我跑了：

cython --embed -o defer4.c defer4.py;
gcc -Os -I /usr/include/python3.5m -o defer4 defer4.c -lpython3.5m -lpthread -lm -lutil -ldl

这在同一文件夹中创建了一个名为defer4的可执行文件。然后我运行./defer4并收到此错误：

我一直在浏览一些文档，以了解是否有关于新Python可能会产生问题的内容，或者新Python是否正在改变其处理方式延期/发电机。我找不到任何东西。

你知道为什么即使是高速公路自己的例子也会引起这个问题吗？

Answer 1

Python中没有任何改变应该破坏它，我只是在Ubuntu 16.04和18.04系统上测试它，分别使用python 3.5.2和3.6.5并且一切正常。

所以问题在于你试图运行这个问题，这是高速公路没有正式支持的，所以不幸的是你几乎都在自己身上。

基本的Autobahn / Twisted示例在Python 3.5
