[bug\_fix] ERR\_DLOPEN\_FAILED: Incompatible architecture \(x86\_64 vs arm64\) for native module

Delete node\_modules and lockfile, ensure you are running an ARM64 \(Apple Silicon\) version of Node \(not Rosetta x86\_64\), and reinstall so the native module compiles or downloads the correct architecture binary. Alternatively, use npm rebuild --build-from-source. The root cause is the native addon was compiled or downloaded for Intel x86\_64 but you are running Node on ARM64 \(Apple Silicon\).

Journey Context:
You get a new MacBook Pro with M1/M2 chip, clone your repo, run npm install which completes successfully, but when you start the app you get 'Error: dlopen\(/path/to/binding.node, 0x0001\): tried: ... \(mach-o file, but is an incompatible architecture \(have 'x86\_64', need 'arm64'\)\)'. You check Activity Monitor and see Node is running under Rosetta \(Intel\). You realize you installed Node when your terminal was running in Rosetta mode for some old x86 tool. You try npm rebuild but it still pulls x64 binaries. You try using arch -x86\_64 npm start to force Rosetta mode, which works but is slower. The real fix is to ensure your Terminal is not using Rosetta, install the ARM64 version of Node \(from nodejs.org or nvm\), delete node\_modules and package-lock.json, and reinstall so node-pre-gyp downloads the darwin-arm64 binary or compiles from source for the correct architecture.
