fs包已安裝，報錯如下：

fs in ./~/[email protected]@vue-server-renderer/build.js, ./~/[email protected]@resolve/lib/sync.js and 10 others

To install it, you can run: npm install --save fs

解決方案：如果在webpack.base.conf.js沒有配置node，可以試試配置一下

node: {

    // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it‘s native).
    setImmediate: false,
    // prevent webpack from injecting mocks to Node native modules
 

    // that does not make sense for the client
    dgram: ‘empty‘,
    fs: ‘empty‘,
    net: ‘empty‘,
    tls: ‘empty‘,
    child_process: ‘empty‘
}

fs包報錯， you can run: npm install --save fs
