NPM : checkPermissions Missing write access to /.../node_modules/is

Question

I am getting following error every time I run a npm install on my project:

npm WARN checkPermissions Missing write access to /../node_modules/is
npm ERR! path /.../node_modules/is
npm ERR! code ELOOP
npm ERR! errno -62
npm ERR! syscall access
npm ERR! ELOOP: too many symbolic links encountered, access '/.../node_modules/is'

npm ERR! A complete log of this run can be found in:
npm ERR!     /.../.npm/_logs/2017-07-14T15_19_32_340Z-debug.log

Issue gets resolved after I delete a shortcut file called "is" in my node_modules folder. But it gets re-generated again after one successful npm install run.

Following is my package.json:

    }
}

I tried changing permission to read-write for everyone but no luck.

Answer 1

If you are in a mac or any unix based system try to run the command again as root/Administrator.

sudo npm install

Answer 2

This is a recursive dependency (the is dependency points to node_modules/is, which is also where the is dependency itself will get installed):

"is": "file:node_modules/is"

If you mean to install the is package (this one), remove that line from your package.json and install it properly:

npm i is --save
