出现这样的报错该如何解决,请大佬们给个解决方法 是不是Python的版本不对？看你用的3.9，是不是需要Python2才行？ node.js与系统的python版本冲突 更换python版本，2.x的试试 深巷丶 发表于 2021-11-19 15:35

试过python2.7也不行 howyouxiu 发表于 2021-11-19 15:35
更换python版本，2.x的试试
node和python版本都降级了,也不行 目前的python降级为2.7，node版本是16.5，npm降级为6.14
经测试都不行解决问题 你打开cmd，输入python ，看看默认是不是3.x版本的，如果是就想办法把python命令默认改成2.x的 howyouxiu 发表于 2021-11-19 15:42

之前降级为python2.7版本，并配置了环境变量,也没能解决 lifeixue 发表于 2021-11-19 15:44

报错原因就是python解释器问题，3.x解释器不支持2.x语法。虽然你之前降为2.7并配置了环境，但是默认python解释器可能还是3.x的，所以还是报错，我建议可以先删除3.x的环境变量，只留2.7的，用完再还原
