npm start process exits abruptly

[ahsanbagwan]

When I issue npm start I'm greeted with this error report:

calo@0.0.1 start C:\Users\Desktop\create-react-app-with-server
nf start

[WARN] No ENV file found
[OKAY] Trimming display Output to 61 Columns
11:36:12 AM web.1 | '.' is not recognized as an internal or external command,

[DONE] Killing all processes with signal null
11:36:12 AM web.1 Exited Abnormally
11:36:12 AM api.1 Exited Abnormally

How do I get rid of this problem?

I'm on Windows 7 edition.
Node version: 4.5.0

You should use correct Windows path to 'react-scripts' in foreman's Procfile (remove ./ and replaces slashes by backslashes):
web: node_modules\.bin\react-scripts start
Also you need to edit second line and correctly set environment variable by 'SET PORT=3001' or using cross-env library:
api: SET PORT=3001 ./node_modules/.bin/babel-node server.js
or
api: cross-env PORT=3001 ./node_modules/.bin/babel-node server.js
