React-native-config: Always use .env.dev file

[exhibition315]

Environment:
react-native: 0.55.4
react-native-config: 0.11.5
cross-env: 5.2.0

Folder structure:
root
--app
--package.json
--env
--.env.dev
--.env.staging
--.env.production

NPM command:
"ios": "cross-env ENVFILE=env/.env.staging react-native run-ios --simulator='iphonex'"

Symptom:
Always use .env.dev config file even type npm command as above.

Someone can help me?

Thanks

try
"ios": "ENVFILE=.env.staging react-native run-ios --simulator='iPhoncex'"

Same here. In our case it always picks .env.prod, even when we don't set ENVFILE.
Our command is react-native run-ios.

Okay so after my long battle my conclusion is that java version may break this lib.
I had big problems with jdk 10, whereas on 8 I have none.

@piotrgrundas Looks like this is working for me, question is what are the disadvantages of downgrading from java 10 to java 8? Do you know any?

I did not notice any, to be honest.

Same here. It's work well on android. On iOS, I have to open Xcode, choose scheme and then build.

Hey guys.

I found how to select different .env file.

Root cause is that I set .env file in xcode scheme "Pre-actions".
React-native-config check if any .env file is set in build time.
If "YES", use xcode "Pre-actions" env file.

So, in my case, I set xcode scheme "Pre-actions" and I run npm command as below:

react-native run-ios --scheme test --simulator='XXX'

"test" is scheme name in xcode.
Now I can control which .env file I need!!!

I renamed my schemes on Xcode -> Product -> Scheme -> Manage Schemes like below:

After creating these three Schemes Development, Staging, Production.
I add to package.json these options to run project:

"scripts": {
    "run:ios:dev": "react-native run-ios --scheme Development",
    "run:ios:staging": "react-native run-ios --scheme Staging",
    "run:ios:prod": "react-native run-ios --scheme Production",
 }

This works fine. :)
