Introduction

Running npm install on Windows can sometimes fail with complex errors related to native module compilation. A common culprit is the node-libcurl package, especially when used with newer Node.js versions.

This post addresses errors like permission issues, nasm not found, and failed pre-built binary downloads that cause build failures during npm installation.



The Problem

Typical npm error messages include:

EPERM: operation not permitted while removing directories during cleanup

Failed to download pre-built binaries (404 Not Found)

Falling back to building node-libcurl from source

Errors like Exception: nasm not found. during build

Example environment:

Windows 11 64-bit

Node.js v20.18.3

Python 3.13.1

npm 10.8.2

These errors indicate:

The pre-built binaries for node-libcurl are missing for your specific Node.js and OS version combination.

The build process requires nasm for assembling native code but it isn't found in your system path.

Permission issues may be related to directory locks or running terminals without sufficient permissions.



Root Causes

Version incompatibility: Newer versions of node-libcurl may not have official pre-built binaries for the latest Node.js versions on Windows.

Missing build tools: nasm assembler is required to compile parts of node-libcurl. Without it, the build fails.

File permission restrictions: Windows sometimes restricts folder modifications, especially when files are locked.



Step-by-Step Solution

1. Use a Compatible node-libcurl Version

The latest node-libcurl (e.g., 4.1.0) might not provide Windows pre-built binaries compatible with your Node.js version.

Downgrade to version 4.0.0 or the latest stable version known to support Windows for your Node.js version:

This avoids the need for complex compilation during install.

2. Install nasm (If Building from Source)

If you must build from source:

Download nasm from the official site: https://www.nasm.us/

Add nasm executable path to your Windows environment PATH variable.

Restart your terminal before retrying npm install.

3. Run Terminal as Administrator

To avoid EPERM permission errors:

Close existing terminals.

Open a new Command Prompt or Git Bash as Administrator.

Retry npm install.

4. Clean Your node_modules and Cache

Sometimes stale files cause issues:

Summary

The key fix is to downgrade node-libcurl to a version compatible with Windows and your Node.js version.

Ensure nasm is installed and in your PATH if compilation is necessary.

Running terminals with administrative privileges may solve file permission errors.

By following these steps, you can regain a smooth npm install experience on Windows with native modules like node-libcurl.



For further stability, always verify your Node.js and package versions compatibility, and consult the respective project's documentation for specific OS build requirements.
