Ich habe eine Vue-App, die ich mit npm run start ausführen möchte, aber wenn ich den Befehl über PowerShell oder VS Code-Terminal ausführe, erhalte ich die folgende Fehlermeldung:

Wenn ich den Befehl npm run start命令时，它可以正常工作，但是当我对代码进行更改时，服务器不会热重载。我尝试过卸载和重新安装Vue CLI，并运行npm install von der WSL aus ausführe, funktioniert es einwandfrei, aber wenn ich Änderungen am Code vornehme, wird der Server nicht im laufenden Betrieb neu geladen. Ich habe versucht, die Vue-CLI zu deinstallieren und neu zu installieren und npm install auszuführen.

TL;DR: 运行
npm install。vue-cli-service由@vue/cli-service在你的devDependencies中提供。因为你在npx命令中没有指定包，所以如果它必须在注册表中查找，它会失败。没有npx，你的npm脚本将在node_modules/.bin中查找vue-cli-service。你可以从npm脚本中移除npx，你应该会得到与现在相同的结果。npx找不到vue-cli-service这个事实表明你还没有运行npm install。运行它，你的npm脚本应该可以正常工作。如果不运行npm install，一旦修复了这个问题，你肯定会遇到其他问题。如果出于某种原因，你希望
npm脚本在不运行npm install的情况下工作，你可以告诉npx在注册表中找到二进制文件的位置。将npm脚本中的npx vue-cli-service改为npx -p @vue/cli-service vue-cli-service，这样应该可以解决这个问题。但你肯定会遇到其他问题。无论如何，你都应该运行npm install。但要真正找到问题的根源，你需要弄清楚为什么在WSL和非WSL环境中存在差异。我猜测你在某个全局位置安装了
@vue/cli-service，只有WSL在你的PATH中找到它，但这只是一个猜测。
