I’m having a weird issue with my VSCode setup. When I run node --version in the built-in terminal, it shows version 10.15.0 instantly without any delay. However, when I execute npm --version, it takes around 6 seconds before displaying version 6.7.0.
This seems strange to me because both commands should be quick. Is this delay normal behavior or could there be something wrong with my npm installation? I’m wondering if other developers experience similar performance differences between these two commands in VSCode.
Any insights would be helpful.
The Problem:
You’re experiencing a significant delay when running npm --version in your VSCode’s built-in terminal, while node --version executes instantly. This indicates a problem with npm’s startup process, not necessarily a problem with your npm installation itself. The delay suggests network latency, potential antivirus interference, or issues with npm’s cache or configuration.
Understanding the “Why” (The Root Cause):
npm performs far more operations during startup than node. It checks registry settings, validates cache integrity, and searches for configuration files in parent directories. A delay of several seconds strongly points to one of these processes being slowed down, rather than an issue with npm’s core functionality. Network issues (such as slow internet connection or proxy usage), antivirus software actively scanning npm’s temporary files, or a corrupted npm cache can all cause this type of delay.
Step-by-Step Guide:
- Verify npm Registry: Ensure you’re using the official npm registry. Open your terminal and run:
npm config get registry
If the output is different from https://registry.npmjs.org/, run the following command to correct it:
npm config set registry https://registry.npmjs.org/
-
Temporarily Disable Antivirus: To determine if antivirus software is causing the delay, temporarily disable your real-time scanning for your project’s directory. Try running npm --version again. If the delay disappears, add an exclusion rule in your antivirus settings for your project directory and its node_modules folder.
-
Clear and Verify npm Cache: A bloated or corrupted npm cache can lead to significant delays. Execute the following commands:
npm cache clean --force
npm cache verify
- Check for Proxy Settings: If you’re behind a proxy or using a VPN, npm might be experiencing network latency trying to reach the registry. Check your proxy settings and see if disabling them improves performance. You can check your current proxy settings with:
npm config get proxy
npm config get https-proxy
- Review Global npm Installation: Occasionally, a broken or conflicting global npm package can impact startup performance. Review the integrity of your global installations and attempt to remove any problematic packages if found.
Common Pitfalls & What to Check Next:
- Network Connectivity: Ensure a stable and high-speed internet connection. Run a speed test to rule out connectivity problems.
- Firewall Settings: Confirm your firewall isn’t blocking npm’s access to the internet.
- PATH Environment Variable: Ensure your
PATH environment variable is correctly configured to prioritize your main npm installation over potentially conflicting versions.
- Multiple Node Installations: Avoid having multiple Node.js versions installed as they might clash. Use
nvm (Node Version Manager) for streamlined management of Node.js installations.

check if ur running npm through a proxy or vpn - that’s what usually slows things down for me. also make sure your PATH has node/npm in the right order. sometimes vs code picks up weird npm versions that run slower than your main install.
Had this exact problem about a year ago - drove me absolutely nuts for weeks. Turns out npm’s cache verification was the culprit. Every startup, npm checks cache integrity, which crawls on some systems or when the cache gets corrupted. Fixed it by nuking the cache with npm cache clean --force then running npm cache verify. Commands went back to running instantly like node does. My cache was bloated with corrupted entries causing the delay. Also check your global packages - sometimes a broken global install causes these startup delays.
I’ve dealt with this performance nightmare for years across tons of projects. Yeah, cache issues and registry timeouts are part of it, but there’s a better way to handle this.
The real culprit? npm’s startup overhead mixed with VSCode’s terminal setup. Instead of constantly debugging cache corruption or registry settings every time this happens, I just automated the whole thing.
Built a workflow that watches command performance and handles npm optimization automatically. When it spots slow npm responses, it cleans cache, checks registry connections, and switches to faster package managers if needed. No more 6-second waits or running cleanup commands manually.
Best part? Set it once and you’re done. Your dev tools stay optimized without you touching anything. Rolled this out to multiple teams and completely killed these performance problems.
