python 3.6 安装 Twisted 错误与解决

python 3.6 安装 Twisted 错误与解决

当我pip install scrapy过程中发现Twisted报错。

于是我尝试pip install twisted单独安装Twisted, 依然是报错。

后来发现原来是twisted和高版本的python有兼容性问题。

那么怎么结局呢？

我发现了Python扩展包的非官方Windows二进制文件里有：

Twisted, an event-driven networking engine.

赶紧的，到https://www.lfd.uci.edu/~gohlke/pythonlibs/下载了Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl

执行：

pip install  Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl

依然错误了。报错显示说，我的平台不能运行这个。

于是我下载另一个版本Twisted‑17.9.0‑cp36‑cp36m‑win32.whl

执行：

pip install  Twisted‑17.9.0‑cp36‑cp36m‑win32.whl
