npm安装不会修改react应用程序中的package.json

Question

我刚刚通过"npx create- React - App“创建了react app，然后当我执行"npm install redux”或"npm install --save-dev redux“或"npm install --save redux”时，它并没有修改package.json

我用"react-redux"，“react-thunk”做了同样的事情...但还是..。package.json保持不变。

我不知道如何解决这个问题。求求你帮帮我。

确保在执行NPM脚本时位于正确的目录中，该目录必须与package.json文件所在的目录相同。
