1.尝试删除node_modules后 npm install 没有用。
2.重新安装node.js也不管用。
尝试安装
npm i -g @vue/cli
这个错误提示意味着vue-cli-service命令无法在命令行中执行。这通常是因为你的环境变量没有设置正确的PATH路径，或者你没有在项目中正确安装依赖。以下是一些可能的解决方法：
1.确保你在项目根目录下运行命令行。在项目根目录下运行命令行可以保证vue-cli-service命令能够正确执行。
2.确保你已经在项目中正确安装了依赖。你可以在命令行中运行 npm install 或 yarn install，以确保你的项目中安装了所有依赖。
3.确保你已经正确安装了vue-cli。你可以通过运行 npm install -g @vue/cli 或 yarn global add @vue/cli 来全局安装vue-cli。
4.确保你已经添加了vue-cli-service命令到你的环境变量中。如果你使用的是Windows操作系统，你可以在环境变量中添加以下路径：%USERPROFILE%\AppData\Roaming\npm。如果你使用的是Linux或MacOS，你可以在终端中运行以下命令：export PATH=$PATH:~/.npm-global/bin。
如果以上方法都没有解决你的问题，你可以尝试重新安装node.js和npm，或者在Vue CLI官方社区中提问以获取更多帮助。
- 这个问题的回答你可以参考下: https://ask.csdn.net/questions/7501649
- 这篇博客也不错, 你可以看下vue-cli3前端踩坑记以及一种多项目共用局部node_modules的新方法
- 除此之外, 这篇博客: 技术文档（1）vue-cli创建项目中的 node_modules 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
node_modules里面是项目依赖包，其中包括很多基础依赖，也可以根据需要安装其他依赖。
如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 写成博客, 将相关链接放在评论区, 以帮助更多的人 ^-^
