Setting environment variables package.json in Windows 10
On Windows you have to separate the command of setting a variable from the one which runs the server with the && operator.
That being said, you have to do something like this:
"server": "set SERVERPORT=3002 && node ./fiboserver"
Make it cross-platform by using cross-env:
"server": "cross-env SERVERPORT=3002 node ./fiboserver"
I've gone through the same problem and used one of the following methods.
Method 1
If I run (without using the npm wrapper script)
HOST=0.0.0.0 PORT=8000 ./node_modules/.bin/react-scripts start
it works fine. As Quentin says,
Must be something to do with how npm shells out then
To fix it, I've gone to package.json and changed the "start" script to
"start": "./node_modules/.bin/react-scripts start",
Then npm start works fine.
Method 2
Use the cross-env package.
For that install it using the following command
npm i cross-env
then go to package.json and change it to
"start": "cross-env ./node_modules/.bin/react-scripts start",
And then running npm start will also work fine:
You can set bash as package.json scripts runner and it's will work in windows and linux.
Just set it once:
- for yarn
yarn config set script-shell /bin/bash - for npm
npm config set script-shell /bin/bash
Or "C:\\Program Files\\git\\bin\\bash.exe" instead /bin/bash
It's will allow you to run npm script cross-platform:
"server": "SERVERPORT=3002 node ./fiboserver"
