Starting the packager in a new window is not supported on Windows yet.
Please start it manually using 'react-native start'.
We believe the best Windows support will come from a community of people
using React Native on Windows on a daily basis.
Would you be up for sending a pull request?

Answer 1

I ran into the same problem. You need to set JAVA_HOME environment variable. To do that:

1. Open your terminal by pressing Ctrl+Alt+T.
2. Enter the following command: $ subl /etc/environment.

3. Depending on where you installed your Java, you will need to provide the full path. For this example, I installed JDK 1.7 in the /usr/lib/jvm/jdk1.7.0_79 directory. Scroll to the end of the file and enter the following:

   JAVA_HOME="/usr/lib/jvm/jdk1.7.0_79" export JAVA_HOME

4. Save your file and exit sublime.
5. Lastly, reload the system PATH with the following command: $ . /etc/environment.

This should fix your issue.

If you are working with react native, just make sure you set up environment variables correctly for java compiler. after this goto package.json file in your project:

change this:

"react-native": "https://github.com/expo/react-native/archive/sdk-31.0.0.tar.gz",

to: "react-native": "0.57.5",

save and run npm install
