• PR步骤 ```shell script

首先fork gocolly 到自己的GitHub

然后clone到本地

(.py3) pro:github play$ mkdir PR (.py3) pro:github play$ cd PR (.py3) pro:PR play$ git clone git@github.com:makelove/colly.git Cloning into 'colly'... remote: Enumerating objects: 130, done. remote: Counting objects: 100% (130/130), done. remote: Compressing objects: 100% (97/97), done. remote: Total 1797 (delta 33), reused 52 (delta 8), pack-reused 1667 Receiving objects: 100% (1797/1797), 8.16 MiB | 43.00 KiB/s, done.
