Unable resolve dependency after vue upgrade - node.js

Question

I try to upgrade my vue version from 3.0.2 to latest version with syntax:
vue upgrade
after that, my vue #vue/cli-service is upgraded to 5.0.8
But then when the process is want to upgade #vue/cli-plugin-babel and #vue/cli-plugin-eslint it say an error:
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: app-backend-vue#0.1.0
npm ERR! Found: eslint#6.8.0

npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
My devDependencies in package.json:
"devDependencies": {
"#vue/cli-plugin-babel": "^4.5.19",
"#vue/cli-plugin-eslint": "^4.5.19",
"#vue/cli-service": "~5.0.8",
"#vue/compiler-sfc": "^3.0.0",
"babel-eslint": "^10.1.0",
"eslint": "^6.8.0",
"eslint-plugin-vue": "^7.0.0-0"
},
How to fix this? And how to clearly upgrade my vue version?
Before the upgrade, my devDependencies were
"#vue/cli-plugin-babel": "~4.5.0",
"#vue/cli-plugin-eslint": "~4.5.0",
"#vue/cli-service": "~4.5.0",
"#vue/compiler-sfc": "^3.0.0",
"babel-eslint": "^10.1.0",
"eslint": "^6.8.0",
"eslint-plugin-vue": "^7.0.0-0"
