How to Fix
Cursor Deployment Errors

Why Cursor Apps Fail to Deploy

Cursor generates code rapidly through iterative AI conversations. Each iteration adds features or fixes bugs, but the cumulative effect can create inconsistent architecture. When it is time to deploy, these inconsistencies surface as build failures.

Unlike code written by a single developer with a consistent vision, Cursor-generated code can have conflicting patterns — different files using different conventions, inconsistent error handling, and mixed approaches to the same problem.

Error: Build Fails with Import Errors

This is the most common Cursor deployment error. Imports fail because the file path or package name is slightly different in production than in Cursor's context.

Fix: Run npm run build locally first. Fix every import error before deploying. Check for case sensitivity issues — Mac is case-insensitive but Linux servers are not.

Error: Environment Variables Undefined

Cursor often uses hardcoded values during development. These work in Cursor's environment but fail in production.

Fix: Search your codebase for hardcoded URLs, API keys, and secrets. Replace them with environment variables. Add each one to your hosting platform's environment variable settings.

Error: TypeScript Compilation Failures

Cursor generates TypeScript quickly, sometimes with less-than-perfect types. Strict TypeScript compilation catches these issues in CI.

Fix: Run tsc --noEmit locally. Fix type errors. If time is short, consider temporarily lowering TypeScript strictness in tsconfig.json for the build.

Iterative Code Drift

The more iterations you make with Cursor, the more patterns diverge. Functions that should be shared get duplicated. Imports become inconsistent. The codebase grows in size but not in coherence.

Fix: Schedule a refactoring session to unify patterns. Group similar components, consolidate duplicated logic, and standardize imports. This is a common service we provide — most Cursor refactoring jobs take under 48 hours.
