我在Visual Studio Code中有一个VueJS 2.x应用程序，我从3年前就没有碰过它。
今天我想构建它，所以我使用以下命令将我的nodejs版本设置为12.0.0：

NVM USE 12.0.0

然后删除node_modules文件夹和package-lock.json，并在终端中输入：

npm install

所有的工作没有错误，然后我键入：

npm run serve

我得到了以下错误：

> vue-cli-service serve

/c/Dev/TestVue/node_modules/.bin/vue-cli-service: line 2: sed: command not found
/c/Dev/TestVue/node_modules/.bin/vue-cli-service: line 2: dirname: command not found
/c/Dev/TestVue/node_modules/.bin/vue-cli-service: line 4: uname: command not found
internal/modules/cjs/loader.js:613
    throw err;
    ^

Error: Cannot find module 'C:\@vue\cli-service\bin\vue-cli-service.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:610:15)

    at Function.Module.runMain (internal/modules/cjs/loader.js:826:10)
    at internal/main/run_main_module.js:17:11
This is killing me because I remember it was working perfectly so not sure if maybe I'm not using the right versions of node.
