Get Full Details of Your React Native Environment

When debugging build issues or setting up a new machine, knowing exactly what is installed — and which versions — saves a lot of guesswork. These scripts collect system information, installed binaries, SDKs, IDEs, and npm packages for a React Native environment on both Windows and macOS.

Windows (PowerShell)

How to run

  1. Save the script as react-native-info.ps1
  2. Open PowerShell and navigate to the file location
  3. Allow script execution for the current session and run it: 
Set-ExecutionPolicy Unrestricted -Scope Process
.\react-native-info.ps1
Enter fullscreen mode Exit fullscreen mode

# Get System Info
Write-Host "System info`n"

Write-Host "System:"

# Get Installed Binaries

# Get Installed Managers

$androidStudio = (Get-Command "C:\Program Files\Android\Android Studio\bin\studio64.exe" -ErrorAction SilentlyContinue) ? "Installed" : "Not Installed"
Write-Host "   Android Studio: $androidStudio"

# Get npm package versions
Write-Host "`nnpm Packages:"

$reactNativeVersion = npm show react-native version
Write-Host "   @react-native-community/cli: $reactNativeCli"

Write-Host "   *react-native*: $($globalReactNative -join ', ')"

macOS (Bash)

How to run

  1. Save the script as react-native-info.sh
  2. Make it executable: 
chmod +x react-native-info.sh
Enter fullscreen mode Exit fullscreen mode
  1. Run it: 
./react-native-info.sh
Enter fullscreen mode Exit fullscreen mode

Script 

#!/bin/bash

echo "   Shell: $SHELL"

# Installed Binaries
echo -e "\nBinaries:"

What Each Script Collects

Section Details
System OS name, CPU, total memory, shell version
Binaries Node, Yarn, npm, Watchman
Package managers Chocolatey / Scoop (Windows), Homebrew (macOS)
SDKs Android SDK path, Java version
IDEs Xcode (macOS only), Android Studio
npm packages Latest published versions of core RN packages
npm global Globally installed React Native packages

Notes

  • The PowerShell script requires Set-ExecutionPolicy Unrestricted -Scope Process to run unsigned scripts. This only affects the current session and does not change your system policy permanently.
  • The Bash script fixes a minor bug in the original — $ANDROID_HOME now uses ${ANDROID_HOME:-"Not Found"} instead of echo $ANDROID_HOME which would silently print nothing if the variable is unset.
  • The npm show calls fetch the latest published version from the registry, not what is installed locally. To check locally installed versions, use npm list --depth=0 inside your project instead.
