Preview Log repeats to reload (Vue packages version mismatch error)

Targets
Projects who use Vue.js and libraries that depend on Vue.js (such as vue-template-compileror vue-loader ) and do not have fixed versions in package.json
Incident
The following error causes the preview log to reload repeatedly.
[webpack-cli] Error:
​
Vue packages version mismatch:
​
This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.
Cause
If a minor version of a Vue.js related library such as vue-template-compiler or vue-loader is updated and there is an inconsistency with the version of Vue.js used in the project, the above error will occur.
How to fix it
Open package.json and fix the version by removing^from the versions of Vue.js and related libraries defined in devDependencies and dependencies.
  "dependencies": {
    ・・・
    "vue": "^2.6.14",
    "vue-onsenui": "^2.6.4"
    ・・・
  },
  "devDependencies": {
     ・・・
    "vue-loader": "^15.9.8",
    "vue-template-compiler": "^2.6.14",
    ・・・
  }
↓
  "dependencies": {
    ・・・
    "vue": "2.6.14",
    "vue-onsenui": "2.6.4"
