What’s the Problem?
Before we dive into the solutions, let’s take a step back and understand the issue at hand. When you run npm install express https or yarn add express https, you might encounter errors that look something like this:
npm ERR! code ECONNRESET npm ERR! errno ECONNRESET npm ERR! network request to https://registry.npmjs.org/express failed, reason: connect ETIMEDOUT 151.101.196.162:443 npm ERR! network This is a problem related to network connectivity. npm ERR! network In most cases you are behind a proxy or your network setup is not correct. npm ERR! network npm ERR! network If you are behind a proxy, please check your proxy settings. npm ERR! network A complete log of this run can be found in: npm ERR! /home/user/.npm/_logs/2023-02-20T14_30_51_055Z-debug.log
Or, you might see something like this:

Causes of the Error
There are several reasons why you might be experiencing these errors. Don’t worry, we’ll cover them all!
- Network Connectivity Issues: A poor internet connection or restrictions on your network might be preventing npm from downloading the required packages.
- Proxy Settings: Your proxy settings might be blocking the requests to the npm registry.
- Node.js or npm Version Issues: An outdated version of Node.js or npm might be causing compatibility problems.
- System Configuration: System-specific configurations, such as firewalls or antivirus software, might be interfering with the installation process.
- Package Corruption: Corrupted package files or incomplete downloads can cause installation errors.
- Dependency Conflicts: Conflicts between dependencies or incompatible versions might be preventing the installation from completing successfully.
Solutions
Now that we’ve covered the possible causes, let’s dive into the solutions!
Solution 1: Check Your Network Connectivity
Ensure you have a stable internet connection. Try restarting your router or modem, and then attempt the installation again.
Solution 2: Configure Your Proxy Settings
If you’re behind a proxy, you’ll need to configure your proxy settings for npm. You can do this by running the following commands:
npm config set proxy http://your-proxy-url:port npm config set https-proxy http://your-proxy-url:port
Replace http://your-proxy-url:port with your actual proxy URL and port.
Solution 3: Update Your Node.js and npm Versions
Make sure you’re running the latest versions of Node.js and npm. You can update them using the following commands:
npm install -g n n latest
This will install the latest version of Node.js and npm.
Solution 4: Disable System Configurations
Temporarily disable any firewall or antivirus software that might be interfering with the installation process.
Solution 5: Clean and Reinstall Packages
Try cleaning the npm cache and reinstalling the packages:
npm cache clean --force npm uninstall express https npm install express https
Solution 6: Resolve Dependency Conflicts
Identify any conflicting dependencies and resolve them by installing the correct versions. You can use npm ls express https to list the installed versions and dependencies.
Additional Tips
To avoid future installation errors, make sure to:
- Regularly update your Node.js and npm versions to ensure you have the latest security patches and features.
- Use a reliable internet connection to prevent network connectivity issues.
- Configure your proxy settings correctly to avoid proxy-related errors.
- Keep your system configurations up-to-date to prevent system-specific issues.

Here are 5 Questions and Answers about “npm packages express and https installation error”:
Frequently Asked Question
Having trouble with npm packages express and https installation error? Don’t worry, we’ve got you covered! Check out these frequently asked questions to get back on track.
Why do I get an error when installing express and https packages using npm?
This error usually occurs when there’s a conflict with another package or a versioning issue. Try uninstalling and reinstalling the packages, or check if your package.json file is up-to-date. You can also try installing a specific version of the packages using npm install express@4.17.1 https@1.0.0, for example.
What’s the difference between express and https packages, and do I need both?
Express is a Node.js web framework, while https is a built-in Node.js module that provides HTTPS functionality. You’ll need express to build your web application, and https to enable secure communication. You can use express without https, but it’s highly recommended to use both for a production-ready application.
How do I fix the ” Cannot find module ‘https'” error when requiring https in my Node.js application?
This error usually occurs when the https module is not properly installed or imported. Make sure you’ve installed the https package using npm install https, and then require it correctly in your application using const https = require(‘https’);.
Can I use a self-signed certificate with the https package, or do I need a trusted SSL certificate?
You can use a self-signed certificate for development purposes, but it’s strongly recommended to use a trusted SSL certificate from a reputable Certificate Authority (CA) for production environments. Self-signed certificates can cause security warnings and errors in clients, while trusted SSL certificates ensure secure and trusted communication.
How do I troubleshoot npm installation errors for express and https packages?
When troubleshooting npm installation errors, try checking the npm log for more detailed error messages, or use the –verbose flag with npm install to get more output. You can also try clearing the npm cache using npm cache clean –force, or reinstalling node and npm to start from scratch.
