Answer 1

应该是你的package.json格式有问题请看你的package.json中的scripts部分，test命令后面的`"echo"Exception..."中双引号没有转义，导致JSON结构被破坏了
"test":"echo"Exception..."
//应该是
"test":"echo\"Exception..."

这个是报的错误，这个配置是错了什么问题呢，请大神看看呢，谢谢
{"name":"react-webpack","version":"1.0.0","description":"","main":"index.js","scripts":{
"build":"webpack"
},"keywords":[],"author":"","license":"ISC","devDependencies":{
"webpack":"^4.1.1",
"webpack-cli":"^2.0.12"
}}
这是json文件的内容，这里script里面应该怎么修改的呢，谢谢
