Question

after making a software to my laptop I installed all the programs includes node js my OS windows

$ node -v
v8.11.1

and the npm

$ npm -v
v5.6.0

when I tried to install npm globally it's gave me this error :

$ npm install -g
npm ERR! code ENOLOCAL
npm ERR! Could not install from "" as it does not contain a package.json 
file.

npm ERR! A complete log of this run can be found in:

or even when I tried to install it locally to a repository it's gave me:

$ npm install
npm WARN saveError ENOENT: no such file or directory, open 
'C:\Users\Aroma\Desktop\app\package.json'
npm notice created a lockfile as package-lock.json. You should commit this

Answer 1

Try this command to change the npm version:
npm -g install npm@4.2.0
it works for me on this issue.

Answer 2

I had same problem. I solved in this way.

Step 1: Open the command prompt as an Administrator and run npm install -g create-react-app to solve the npx issue.

Step 2: run npx create-react-app your-app-name

Answer 3

I got the same issue. What I did was to rename the package-lock.json by:

mv package-lock.json package.json

, and then this issue should be solved.

If you get the next issue of showing a message: [...] / rollbackFailedOptional: verb npm-session xxxxxxxxxxx , then you could do

1. sudo npm config rm proxy
2. sudo npm config rm https-proxy
3. sudo npm install npm@latest -g

These steps works for me. Hope they could be helpful to you too.
