Error running npm install and start: "npm WARN tar ENOENT: no such file or directory, open"

Question

I’m getting some errors running some files on Node.js. I downloaded 2 files on Github, and in a tutorial simply tells to run the following commands:

npm install

npm start

The Operating System is Windows 10.

First I installed Node.JS. Then I opened windows Powershell and walked to the file folder.

The command dir returns the following folders and files:

C:\Users\Evarist\Desktop\yEarn\iearn-finance-master\iearn-finance-master>dir
 O volume na unidade C não tem nome.
 O Número de Série do Volume é 1CE1-A159

The command npm install the result came out:

   C:\Users\Evarist\Desktop\yEarn\iearn-finance-master\iearn-finance-master>npm install
npm WARN tar ENOENT: no such file or directory, open 'C:\Users\Evarist\Desktop\yEarn\iearn-finance-master\iearn-finance-master\node_modules\.staging\bip39-5f8d4250\package.json'

    [.....]

The files I downloaded:

https://github.com/iearn-finance/iearn-finance

https://github.com/iearn-finance/itoken

How to solve this?

Answer 2

So the entire Node project needs package.json. It’s responsible for uploading everything your project needs. If your project doesn’t have Packge.json it won’t be able to understand where it has to download libraries, other necessary data and the like.

Do the following, download the project again and give the npm install

Answer 3

Do the following:

• renames your folder to finance
• enter the folder and remove the node_modules, the package json. and the package-lock.json
• then runs npm install
