1.報錯:
The 'mode' option has not been set, webpack will fallback to 'production' for this value.
原因:啟動時,沒有指定是開發模式還是線上模式
解決辦法:
在啟動時添加:--mode development 例如:"dev": "webpack server --mode development"
2.報錯:
WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
WARNING in webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.
這3個問題都是一個原因:資源(asset)和入口起點超過指定文件限制,需要在 vue.config.js 文件內做如下配置
解決辦法:
在webpack.config.js文件中添加
//警告 webpack 的性能提示 performance: { hints:'warning', //入口起點的最大體積 maxEntrypointSize: 50000000, //生成文件的最大體積 maxAssetSize: 30000000, //只給出 js 文件的性能提示 assetFilter: function(assetFilename) { return assetFilename.endsWith('.js'); } },
