Question

I am trying to run an Ethereum project that I downloaded from github. I have installed npm and nodejs. Now, when I run

npm run dev

I am getting the following error:

'env' is not recognized as an internal or external command,
    operable program or batch file.
    'env' is not recognized as an internal or external command,

Answer 1

According to the error, it seems like the module required to run this project (module env) is not installed in your system. You can solve this error by installing that module

$ npm update
$ npm install dotenv –save
