cnpm install报错Install fail! RunScriptError: post install error

Question

运行一个项目，但是cnpm install很多次一直报错。

报错信息如下：
[1/3] scripts.install @vue/cli-plugin-eslint@3.12.1 › yorkie@^2.0.0 run "node bin/install.js", root: "C:\Users\APPLE\Documents\DDH\dangdanghao\danghao\node_modules\_yorkie@2.0.0@yorkie"
'node' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

Answer 1

可以试试用yarn代替安装

Answer 2

使用 nrm 管理 npm 镜像源

$ npm i -g nrm
$ nrm ls

* npm -------- https://registry.npmjs.org/
  yarn ------- https://registry.yarnpkg.com/
  cnpm ------- http://r.cnpmjs.org/
  taobao ----- https://registry.npm.taobao.org/
  nj --------- https://registry.nodejitsu.com/
  npmMirror -- https://skimdb.npmjs.com/registry/
  edunpm ----- http://registry.enpmjs.org/

$ nrm use taobao

  Registry has been set to: https://registry.npm.taobao.org/
  
$ npm i

能不用 cnpm 就不用 cnpm, cnpm 是通过自建镜像源加快 node_module 安装速度，但是这个封装经常各种问题，故而只需要使用其镜像源加速就行

推荐 yarn

1、离线模式
2、贼快

Answer 3

可能是cnpm 环境变量没有全局注册
