我正在将一个Vue.js应用程序移动到一个新的存储库中，从它的旧主机中提取它。
在这一点上，我已经字面上复制的应用程序从一个文件夹到另一个，但它不会建立。它建立在第一个文件夹，但不是在第二个。
只要我输入npm run build/npm run build-app-only（或其他任何东西），我就得到了这个...
npm ERR! missing script: vue-cli-service
或
node-sass is not recognised as an internal or external command
这是我的软件包的脚本部分。json....

我从根文件夹运行，package.json位于该文件夹。
我试过在另一个文件夹中制作另一份副本（那也坏了）。
我再次尝试手动运行npm i（尽管我复制了所有文件）。
我已经搜索了互联网，但所有的解决方案似乎都围绕着脚本没有被发现是一个自定义脚本，但事实并非如此-我定义的脚本被发现很好，但从脚本本身调用似乎不再工作，因为移动。
