All Errors

The "Missing script: dev" error occurs when running npm run dev but no dev script is defined in package.json. Add a development server script appropriate for your framework to resolve this.

Exit code 134 indicates SIGABRT (abort signal), typically caused by JavaScript heap out of memory during npm install or build. Increase Node.js memory allocation to resolve this.

Postinstall script failures occur when a package's setup script fails after download. Common causes include missing build tools, permission issues, or network problems downloading binaries.

SyntaxError means your Python code has invalid syntax that violates Python's grammar rules. The error message usually points near the problem. Common issues are missing colons, incorrect indentation, or mismatched parentheses.

This error occurs when your import statement has incorrect syntax, typically due to mismatched curly braces, imports at wrong scope level, or file not being treated as a module. In React, common causes include forgetting curly braces for named exports or incorrectly using default import syntax.

The prepare script ELIFECYCLE error occurs when a package's prepare hook (typically running npm run build) fails. Check build configuration and ensure all build dependencies are installed.

SIGTERM errors in npm occur when a process is terminated externally, often by Docker, CI timeouts, or process managers. Run Node directly instead of via npm for proper signal handling.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

This error occurs when a class implements an interface but one or more of its properties or methods have incompatible types or signatures. The fix involves aligning the types, signatures, and access modifiers between the class and interface.

This ESLint warning appears when a context value from useContext is used inside useEffect or another hook without being included in the dependency array. React needs to track context values as dependencies to ensure effects re-run when the context changes.

The "cb() never called" error is an internal npm failure, typically caused by cache corruption or network issues. Clear the npm cache and verify your network connection to resolve this.

The node-gyp rebuild error occurs when compiling native C++ modules fails. Install platform-specific build tools (Python, C++ compiler) to resolve this error.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

This warning occurs when npm detects that cached tarball data is outdated or corrupted, typically due to network issues, cache corruption, or mismatched checksums. While npm usually recovers automatically, persistent warnings indicate stale cache data that should be refreshed or cleared.

The ENEEDAUTH error occurs when npm cannot find valid authentication credentials while attempting to publish a package. This typically happens when you're not logged in to the registry, have an invalid or expired token, or misconfigured .npmrc settings.

JSX transform failures occur when your build tool cannot convert JSX syntax into JavaScript, typically due to missing Babel plugins, incorrect configuration, or version mismatches between React and your build tooling.

The npm E401 error occurs when npm cannot authenticate your credentials or access token for the npm registry. This typically happens due to expired tokens, incorrect passwords, stale credentials in .npmrc files, or authentication configuration issues.

The ENEEDAUTH error occurs when npm cannot find valid authentication credentials for the registry you're trying to access. This typically happens after logging out, using an expired token, or misconfiguring your .npmrc file.

The npm E401 error occurs when your authentication token or credentials for a private npm registry have expired, been invalidated, or are misconfigured in your .npmrc file. This prevents npm install from accessing private packages you have permission to use.

The EINVALIDPROXY error occurs when npm detects malformed proxy settings in your configuration. This typically happens when the proxy URL is missing the protocol prefix (http:// or https://), contains unencoded special characters, or has incorrect formatting.
