我已将我的 package.json 文件在 react 项目中上移了一个文件夹，现在 `npm start` 不起作用

Question

my current folder structure is

   -- project folder
         |-- package.json
         |-- react-project
                  |-- src folder
                  |-- public folder

My node version is 18

In order for npm start to work, you have to run the command from the same directory as your package.json .

node_modules , package-lock.json , and package.json should always be at the root of the project as a good practice.

If you move these files/folders it can disrupt the pathing of them.

For example, inside package.json at the top you will a line somewhat like: "main": "node_modules/expo/AppEntry.js" . If you move node_modules or package.json , then this will no longer work. It would need to be changed to something like, "./node_modules" or "../node_modules"

If there is a specific reason you need to move this folder, then you will have to do some reconfiguring to ensure the pathing is correct.
