yarn install报依赖版本错误怎么解决呢？

Question

vue2工程使用yarn install --foce安装node_modules依赖报以下错咋整呢？
npm i也不好使，会报个其他错

说js-beautify依赖node版本不对，但是本机只能用node 12.20.0版本的

package.json文件指定js-beautify版本也不好使，求大佬们帮帮忙

Answer 1

nodejs 版本问题，包 js-beautify@1.15.1 需要nodejs 14+，你项目当前的nodejs版本是12.12.0：
解决方法：

1. 可以尝试将devDependencies和devDependencies中版本号前面^或~移除试试
2. 升级 nodejs 版本

Answer 2

把 package.json 里面的依赖版本中的 ~ 和 ^ 符号全部去掉，都设置为固定的版本号之后 yarn cache clean 清一下缓存，删除 node_modules 目录重新 yarn 安装依赖。

看上面的异常输出是 js-beautify 的 1.15.1 需求的 nodejs 版本比较高，使用 1.14.2 应该就没问题了。我这边 add 是不会有 ERROR 抛出的，会有一些 WARNING 但是问题不大。

不知道你固定版本之后的 不好使 指的是什么。固定版本应该是不会有 ERROR 抛出的
