This version of Node.js requires NODE_MODULE_VERSION Y' (better-sqlite3, bcrypt, sharp...) ## Body Cause (Documented platform behavior): Native addons are ABI-specific; Node checks NODE_MODULE_VERSION at load time. Fix status: documented_behavior Limitations: - ERR_DLOPEN_FAILED code is from general Node behavior, not verified in the cited file. Other error fragments: - Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`). Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/nodejs/node/a2a064c76afe42fedf061d976de8dff69ef2feaf/src/node_binding.cc (official_docs, unknown, documented_behavior): node_binding.cc DLOpen reports ' was compiled against a different Node.js version using NODE_MODULE_VERSION %d. This version of Node.js requires NODE_MODULE_VERSION %d. Please try re-compiling or re-installing the module (for instance, using npm rebuild or npm install).'
