npm安装插件时遇到：npm ERR! code ERESOLVE或者 code ERESOLVE npm ERR! 错误

1.问题

我们在使用npm install ...时，遇到以下问题：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve
npm ERR!
npm ERR! While resolving: @vue/eslint-config-standard@6.1.0
npm ERR! Found: eslint-plugin-vue@8.7.1
npm ERR! node_modules/eslint-plugin-vue
npm ERR! dev eslint-plugin-vue@"^8.0.3" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer eslint-plugin-vue@"^7.0.0" from @vue/eslint-config-standard@6.1.0
npm ERR! node_modules/@vue/eslint-config-standard
npm ERR! dev @vue/eslint-config-standard@"^6.1.0" from the root project
npm ERR!
npm ERR! Conflicting peer dependency: eslint-plugin-vue@7.20.0
npm ERR! node_modules/eslint-plugin-vue
npm ERR! peer eslint-plugin-vue@"^7.0.0" from @vue/eslint-config-standard@6.1.0
npm ERR! node_modules/@vue/eslint-config-standard
npm ERR! dev @vue/eslint-config-standard@"^6.1.0" from the root project
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.

2.解决方法

参考：npm ERR! code ERESOLVE npm ERR! ERESOLVE could not resolve npm ERR! Vue开发中安装库经常报错
解决方案：
在安装内容的命令后面加上

--legacy-peer-deps

如：
PS E:\web\project-SHP\app\src> npm i less-loader --legacy-peer-deps
added 1 package in 2s

3.补充

运行过程中报错：Module build failed: Error: Cannot find module ‘less’
用上述方式安装 less即可

PS E:\web\project-SHP\app> npm install less --legacy-peer-deps

added 13 packages in 3s
// 成功运行
App running at:

• Local: http://localhost:8080/
• Network: http://10.33.201.152:8080/

4.补充

项目开发过程中报错：code ERESOLVE npm ERR! ERESOLVE could not resolve npm ERR! npm ERR! While Vuex中dispatch没有被定义
在一般情况下书写没有任何问题的时候，观察vue版本和vuex版本是否出现了差错，重新安装vuex的版本即可

5.补充：

项目运行时控制台报错：Refused to apply style from ‘http://localhost:8080/iconfont.css’ because its MIME type (‘text/html’) is not a supported stylesheet MIME type, and strict MIME checking is enabled.

查看自己项目文件夹中是否进行引入了iconfont.css文件，有的话进行注销即可
