babel这个问题咋解决呢各位?

Question

    throw e;

Error: Couldn't find preset "stage-3" relative to directory "E:\myProject\ice-ko
a-vue-mongodb"

我用npm install --save-dev babel-preset-stage-3也没用呀?

Answer 1

弄好了，不是babelrc的问题，把node_modules删掉重新安装一次就正常了

Answer 2

配置一下 .babelrc

{
    "presets": [
        "stage-3"
    ]
}
