               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從 python3.7 開始已經加入保留關鍵字中. 參考: What’s New In Python 3.7, 所以async不能作為函數的參數名.
改正：

1.修改/Library/anaconda3/lib/python3.7/site-packages/pyspider路徑下的python文件中的async為shark（全部替換）

1.run.py
2.fetcher\tornado_fetcher.py
3.webui\app.py
使用替換命令（注意路徑）

            
              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

            
          

再運行 pyspider all 依然報錯

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

再運行pyspider all 成功

這時pyspider的Web服務就會在本地5000端口運行。直接在瀏覽器中打開http://localhost:5000/，即可進入pyspider的WebUI管理頁面，這證明pyspider已經安裝成功了。
