问题： 运行vue项目，使用2G内存，不知道如何更改。

DevOps 要求将前端生成限制为 1GB 的 RAM，防止 Jenkins 实例被关闭。使用标准Vue Cli创建项目，带 TypeScript。但是，TS 类型检查服务会忽略限制其内存使用的所有尝试，这始终为 2048 MB。@vue/cli

禁用它， 但这引入了其他问题。fork-ts-checker-webpack-plugin

$ NODE_OPTIONS=--max_old_space_size=1024 NODE_ENV=production node --max_old_space_size=1024 --max-old-space-size=1024 node_modules/.bin/vue-cli-service build

类型检查不生效，始终是2048 MB 。

解决方式：

• 自定义 Vue CLI 的内置功能来修改 配置：ForkTsCheckerWebpackPlugin`&#fig

// fig.js
​
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');
​
ports = {configureWebpack: config => {
​// get a reference to the existing ForkTsCheckerWebpackPluginconst existingForkTsChecker = config.plugins.filter(p => p instanceof ForkTsCheckerWebpackPlugin,)[0];
​// remove the existing ForkTsCheckerWebpackPlugin// so that we can replace it with our modified versionconfig.plugins = config.plugins.filter(p => !(p instanceof ForkTsCheckerWebpackPlugin),);
​// copy the options from the original ForkTsCheckerWebpackPlugin// instance and add the memoryLimit propertyconst forkTsCheckerOptions = existingForkTsChecker.Limit = 4096;
​config.plugins.push(new ForkTsCheckerWebpackPlugin(forkTsCheckerOptions));},
};

info输出：Starting type 
Using 1 worker with 4096MB memory limit

有关选项的信息， 请参阅此处：configurewebpack

若要查看 Vue CLI 使用的默认 Webpack 配置，vue webpack config

• 在

const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');
const os=require('os');
ports = {//......,chainWebpack: config => {config.plugin('fork-ts-checker').tap(args => {let totalmem=Math.almem()/1024/1024); //get OS mem sizelet allowUseMem= totalmem>2500? 2048:1000;// in vue-cli shuld args[0]['typescript'].memoryLimitargs[0].memoryLimit = allowUseMem;return args})},//......
}

在node_modules/fork-ts-checker-webpack-plugin/lib/index.js

declare class ForkTsCheckerWebpackPlugin {static readonly DEFAULT_MEMORY_LIMIT = 4096;static readonly ONE_CPU = 1;static readonly ALL_CPUS: number;static readonly ONE_CPU_FREE: number;static readonly TWO_CPUS_FREE: number;readonly options: Partial<Options>;
