Error reporting and solution of memory overflow of vscode running packaging Vue project


Error reporting and solution of memory overflow of vscode running packaging Vue project

Recently, when I was working on another old project, I found that the project was unusually large and involved a lot of contents, resulting in memory overflow when I was running. Although it did not affect the running of the code, it was very annoying when it was saved from time to time. There was no way, so I went to find various ways to solve it. The following are the problems encountered and some other people’s solutions

Final solution ——————– March 29, 2022

If the node version is too high, it can only be reinstalled once

I’m really speechless. I hope you can take a warning!!!!!!!!!!!!!!!!

This is the problem. When the project is running, the memory overflows after clicking save. The project is too large

1. Increase memory at startup,

NPM run Dev and NPM run build are directly preceded by – max_ old_ space_ size=4096

 "scripts": {
      "start": "npm run dev",
    "dev": "node --max_old_space_size=4096 build/dev-server.js",
    "build": "node --max_old_space_size=4096 build/build.js",

Add an instruction to scripts
Install two NPM packages: increase memory limit and cross env
After installation, execute NPM run fix memory limit once, and then start NPM run serve

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "fix-memory-limit": "cross-env LIMIT=4096 increase-memory-limit",

2. Then there is another way to installIncrease memory limit and cross env

Global install increase memory limit
npm install -g increase-memory-limit
npm install -g cross-env
Enter the project directory and execute:
npm run fix-memory-limit 

Delete the following
node_ [email protected] Vue in cli. service. js
Manual deletion: - Max old space size = 6144

These are the above two methods. I hope they are useful to you


"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/",
    "start": "npm run dev",
    "build": "node --max_old_space_size=4096 build/build.js"
