Question

Source of problem (I think):

 "scripts": {
        "dev-server": "./node_modules/webpack-dev-server/bin/webpack-dev-server.js --config config/webpack.config.js"
      },

Error log:

> somename@1.0.0 dev-server C:\Users\Admin\Downloads\somename
> ./node_modules/webpack-dev-server/bin/webpack-dev-server.js --config config/we
bpack.config.js

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

I am receiving this error and because of that I'm not able to: npm run dev-server .

Is there a way to replace ./ part?

Answer 1

Just refer to the binary directly:

    "scripts": {
        "dev-server": "webpack-dev-server --config config/webpack.config.js"
     },

npm will run the script in an environment where all the installed packages' binaries (namely node_modules/.bin/ ) are directly available in PATH, including webpack-dev-server .

Also using / as a path separator is preferable in package.json - it works on Windows as well as Linux or OSX.
