Question

昨天，在克隆工作组存储库后，我发现一些非常奇怪的事情。使用npm install安装依赖项后，我无法在项目内启动devserver（或运行任何npm脚本）。奇怪。因此，我然后尝试使用@ vue / cli创建我自己的新项目，并且在那里发生了同样的事情。环境：节点：v14.15.0 NPM：v6.14.8 全局安装的Vue Cli：v4.5.8 macOS Catalina：v10.15.7

项目中的Package.json：

  "name": "eezer_app",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "core-js": "^3.6.5",
    "vue": "^2.6.11",
    "vue-router": "^3.2.0",
    "vuetify": "^2.2.11",
    "vuex": "^3.4.0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-plugin-router": "~4.5.0",
    "@vue/cli-plugin-vuex": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^6.2.2",
    "sass": "^1.19.0",
    "sass-loader": "^8.0.0",
    "vue-cli-plugin-vuetify": "~2.0.7",
    "vue-template-compiler": "^2.6.11",
    "vuetify-loader": "^1.3.0"
  }
}

错误输出：

同样由vue create创建的Vue项目中也出现了相同的错误。

npm似乎正在尝试全局查找依赖包，而不是在node_modules中本地查找依赖包，因为我可以通过在本地node_module .bin中手动选择脚本来运行服务，如下所示：

./node_modules/.bin/vue-cli-service serve

然后它可以完美启动，没有任何故障 ，因此已安装的node_modules等没有任何问题。从昨天开始，我尝试修复此问题，但没有结果。我找到了清除npm缓存，删除本地node_modules和package-lock.json的提示，但它根本不起作用。我什至在Mac上重新安装了CLT。

我的npm怎么了？为什么似乎要在我的全局node_module中寻找依赖关系？

自从我用尽了大多数选择之后，不胜感激任何技巧。

我更新了 Node、NPM、我所有的全局节点模块，运行了 brew update，重新安装了 xcode：sudo rm -rf /Library/Developer/CommandLineTools 然后 xcode-select --install，它似乎又可以工作了。

在使用 vue create 创建的新创建的 Vue 项目中也出现了同样的错误。

使用@vue/cli 创建了一个全新的 vue 项目，并且我能够运行 npm run serve。希望这对面临此问题的其他人有所帮助。

npm run serve给出错误提示：vue-cli-service：在Vue Cli应用程序中找不到命令
