介绍

react的学习知识点以及参数配置可以重复拿来使用。

在安装babel的时候，遇到个Error: Cannot find module '@babel/core’问题，问题产生的原因：babel-loader和babel-core版本不对应所产生的。

babel-loader 8.x对应babel-core 7.x
babel-loader 7.x对应babel-core 6.x

修改.babelrc文件
{
"presets": ["@babel/preset-env", "@babel/preset-react", "mobx"],
"plugins": [
"@babel/plugin-proposal-object-rest-spread",
"@babel/plugin-transform-runtime"
]
}

如果你按上述命令安装完后，相应的版本应该如下图所示，问题也应该解决了。

"@babel/core": "^7.2.2",
"@babel/plugin-proposal-object-rest-spread": "^7.2.0",
