Report #21021

[bug\_fix] The module was compiled against a different Node.js version using NODE\_MODULE\_VERSION XX. This version of Node.js requires NODE\_MODULE\_VERSION YY.

Delete the node\_modules folder and package-lock.json \(or yarn.lock/pnpm-lock.yaml\) and run a fresh install to trigger recompilation of native addons against the current Node version, or run npm rebuild for the specific package. Root cause: Native Node.js addons \(C\+\+ extensions\) compile against specific V8 ABI versions that change with each major Node.js release; the compiled .node binary is incompatible across versions.

Journey Context:
A developer is context-switching between two projects: a legacy API using Node.js 16 and a new microservice using Node.js 18. Using nvm, they switch to Node 18 to work on the new service, then return to the legacy project directory and run nvm use 16 followed by node app.js. The application immediately crashes with an error stating that the module \(for example, bcrypt or sqlite3\) was compiled against NODE\_MODULE\_VERSION 93 \(Node 16\) but the current Node process requires version 108 \(Node 18\). The developer initially panics, thinking they corrupted their node\_modules. They try running npm install, but npm reports that all packages are already installed and up to date, because the package.json hasn't changed. The developer then realizes that native addons are not pure JavaScript—they contain compiled C\+\+ binaries that are specific to the Node.js version used during installation. When they switched Node versions with nvm, the compiled binaries remained compiled for the old V8 engine ABI. The solution is to force a rebuild of all native modules against the current Node headers. They delete the node\_modules folder and the package-lock.json file to ensure a clean slate, then run npm install again. This triggers node-gyp to recompile all native addons against the currently active Node 16 headers. The application starts successfully without the NODE\_MODULE\_VERSION mismatch error.

environment: Projects using native Node.js addons \(bcrypt, sharp, sqlite3, canvas, node-sass\) when switching Node.js versions using nvm, n, or nvm-windows, or when deploying to environments with different Node versions than the local development environment. · tags: node_module_version native-addon abi node-gyp rebuild nvm · source: swarm · provenance: https://nodejs.org/api/addons.html
