cli4升级到cli5运行内存溢出

[web-laoxie]

最近想将一个老项目vue2+cli4的项目升级到cli5，因为老项目的打包和运行速度较慢，想用webpack5进行优化速度。但是当我在使用vue create建立一个空项目，然后再把老代码迁移进去就会导致运行的时候内存溢出，而且运行的日志也看不到具体在哪里卡住了，求教大佬们

下面是vueconfig.js:
`const { defineConfig } = require("@vue/cli-service");
const path = require("path");
const resolve = dir => path.join(__dirname, dir);
var FriendlyErrorsWebpackPlugin = require("friendly-errors-webpack-plugin");
module.exports = defineConfig({
transpileDependencies: true,
devServer: {
client: {
logging: 'info',
overlay: {
errors: true,
warnings: true
}
}
},
chainWebpack: (config) => {
config.resolve.alias
.set("@views", resolve("src/views"))
.set("@assets", resolve("src/assets"))
.set("@api", resolve("src/api"))

    config.plugin("friendly-errors").use(new FriendlyErrorsWebpackPlugin())

    config.module.rule('scss').exclude.add(/node_modules/).end()
    config.cache({
        type: 'filesystem',
        buildDependencies: {
            config: [__filename]
        }
    });
},
css: {
    loaderOptions: {
        sass: {
            additionalData: `@import "~@/styles/base.scss";`,
            // modules: {
            //     auto: () => true
            // }
        },
        // css: {
        //     modules: {
        //         auto: () => true
        //     }
        // }
    }
}

});
`
