pyspider all [python3.7]报错 已解决

报错内容

 Traceback (most recent call last):
      File "/Library/anaconda3/bin/pyspider", line 6, in 
        from pyspider.run import main
      File "/Library/anaconda3/lib/python3.7/site-packages/pyspider/run.py", line 231
        async=True, get_object=False, no_input=False):
            ^
    SyntaxError: invalid syntax

原因是async和await从 python3.7 开始已经加入保留关键字中. 参考: What’s New In Python 3.7, 所以async不能作为函数的参数名.
改正：

1.修改/Library/anaconda3/lib/python3.7/site-packages/pyspider路径下的python文件中的async为shark（全部替换）

1.run.py
2.fetcher\tornado_fetcher.py
3.webui\app.py
使用替换命令（注意路径）

sed -i '' 's/async/shark/g' run.py

sed -i '' 's/async/shark/g' tornado_fetcher.py

sed -i '' 's/async/shark/g' app.py 

2.降低WsgiDAV版本

python -m pip install wsgidav==2.4.1

再运行pyspider all依然报错

解决方法：
Reboot the PC,or remove phantomjs can fix it
查看端口，然后kill phantomjs

再运行pyspider all 成功

这时pyspider的Web服务就会在本地5000端口运行。直接在浏览器中打开http://localhost:5000/，即可进入pyspider的WebUI管理页面，这证明pyspider已经安装成功了。
