接着把这些有错误的模块删了

• cross-spawn

• execa

• jest-cli

• webpack-dev-server

再试试

Saving to C:\Users\01\AppData\Local\Temp\chromedriver\chromedriver_win32.zip

这个卡住了,只能手动下载,然后放到C:\Users\01\AppData\Local\Temp\chromedriver文件夹下,再运行

成功安装

竟然需要装python

下载了3.9.1 提示需要win8以上

下载python-2.7.18.amd64.msi安装

最后才运行成功
