npm notice created a lockfile as package-lock.json. You should commit this file

You can update the existing package-lock.json file instead of creating a new one. Just change the version number to a different one.

{ "name": "theme","version": "1.0.1", "description": "theme description"}

Yes you should, As it locks the version of each and every package which you are using in your app and when you run npm install it install the exact same version in your node_modules folder. This is important becasue let say you are using bootstrap 3 in your application and if there is no package-lock.json file in your project then npm install will install bootstrap 4 which is the latest and you whole app ui will break due to version mismatch.

It should also be noted that one key detail about package-lock.json is that it cannot be published, and it will be ignored if found in any place other than the top level package. It shares a format with npm-shrinkwrap.json(5), which is essentially the same file, but allows publication. This is not recommended unless deploying a CLI tool or otherwise using the publication process for producing production packages.

If both package-lock.json and npm-shrinkwrap.json are present in the root of a package, package-lock.json will be completely ignored.

Yes it is wise to use a version control system for your project. Anyway, focusing on your installation warning issue you can try to launch npm install command starting from your root project folder instead of outside of it, so the installation steps will only update the existing package-lock.json file instead of creating a new one. Hope this helps.

Check for package-lock.json file at C:\Windows\system32.

If it doesn't exist, run cmd as admin and execute the following commands:

Set EXPO_DEBUG=true
npm config set package-lock false
npm install

came out of this issue by changing the version in package.json file and also changing the name of the package and finally deleted the package-lock.json file

If this is output from a Dockerfile then you don't want / need to commit it.

However you will want to tag the base image and any other contributing images / applications.

E.g.

FROM node:12.18.1

I had same issue and the solution was to rename name field in package.json (remove white spaces)

Simply follow below steps to overcome this issue.

1. copy and paste package.json and package-lock.json from some other project, later on you can change/delete the dependencies which you won't require in your project.
2. now run npm install command.

Voilla!!, you got it.
