We've got some error and we try to install optionator but nothing happened. We're using Linux

We're trying to npm i from package.json which include this dependencies

"optionalDependencies": { 
  "eslint-config-<name>": "github:<username>/<repo>" 
} 

then we tried to run npm i optionator but still get the same error

Anyone who experienced this, please help us. Thanks

Answer 1

So if you have not done an npm init then that is the issue. npm init initializes the project and will add the node_modules folder to the working directory, this will set it up as a node project. Then to install a dependency just run a npm install <dependency> although I do recommend doing a --save afterwards as well as it just ensures that the package is put in your current directory

$ npm init
$ npm install optionator --save

Answer 2

Need to give full access to package-lock.json

Answer 3

Nothing worked until when I initialized the project in a new directory and reinstalled all the dependent modules afresh.

Answer 4

If you are using linux do this

sudo eslint init
