错误代码

WARNING in ./node_modules/cesium/Source/ThirdParty/protobuf-minimal.js(Emitted value instead of an instance of Error) Cannot find SourceMap 'protobuf.js.map': Error: Can't resolve './protobuf.js.map' in '/home/c4/Project/YanqiProject/node_modules/cesium/Source/ThirdParty' @ ./node_modules/cesium/Source/Cesium.js 1:0-809:2 @ ./src/components/baseComponets/cesiumExt/index.tsx @ ./src/routers.tsx @ ./src/index.tsx @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/index.tsx

分析

由提示信息可以看出是由于没由找到protobuf.js. map文件所致，引文这是第三方压缩库，是不提供sourcemap文件的，所以我们需要告诉webpack忽略该库的sourcemap信息。

解决

查看webpack的modules配置如下：

rules:[// ...  {        enforce: "pre",        test: /\.js$/,        use: "source-map-loader"  },  // ...]

修改为：

rules:[// ...  {        enforce: "pre",        test: /\.js$/,        use: "source-map-loader",                exclude:[                    path.resolve(path.join(__dirname,  'node_modules/cesium'))                ]  },  // ...]
