CMake '\d' escape sequence error during react-native cli setup on windows

#reactnative #android

So, I choose to use react-native cli over Expo to make my app. As I was setting up, the biggest issue I encountered was the CMake error and I was lost, but here are the sequence of solutions that I tried which resolved my problem!

Solutions I Tried

Install and Set Up Android Studio

Open Android Studio and go to SDK Manager.
Download the latest Android API, SDK Build-Tools, and NDK. > Update environment variables to include paths to Command-Line Tools and Platform Tools.

Ensure that the environment variables are updated to include the latest paths for Command-Line Tools and Platform Tools.

Simplify Java Environment Variables

Ensure only one version of Java (e.g., Java 17 OpenJDK) is set in environment variables.

Locate and Edit CMakeLists.txt

Locate CMakeLists.txt at:

D:\<Project-Name>\node_modules\react-native\ReactAndroid\cmake-utils\default-app-setup\

Update its content to:

cmake_minimum_required(VERSION 3.13)

# Define the library name here.
project(appmodules)

# Check if the host system is Windows
if(CMAKE_HOST_WIN32)
  # Replace backslashes in paths to forward slashes
  string(REPLACE "\\" "/" REACT_ANDROID_DIR ${REACT_ANDROID_DIR})
endif()

# Include the ReactNative-application.cmake file
include(${REACT_ANDROID_DIR}/cmake-utils/ReactNative-application.cmake)
