Suggested October 2023 How To Fix Npm Install Not Working In Windows 11
The NPM install is a command that is used frequently on chúng tôi projects. It allows developers to install and manage packages (or dependencies) for their chúng tôi project. The npm install command is also necessary for chúng tôi projects because it ensures that the project has all the required libraries and modules to function without any issues and allows the user to update the dependencies as new versions are released, making it easier to maintain the code over time.
Despite being a popular tool for installing and managing dependencies for a chúng tôi project, npm install sometimes may not work as expected on Windows 11. The reason can be anything from outdated versions to incompatible configurations. In this post, let us look at how you can fix the npm install not working on your Windows 11 computer.
Fix NPM Install Not Working in Windows 11
Before moving further and trying the methods listed below, we suggest you try basic troubleshooting, like restarting your PC and checking if your internet connection is up and running. If these steps don’t fix the issue, try the following ones.
If the basic troubleshooting steps are not working, update the Node Package Manager on your computer to the latest version. A new update may include bug fixes to your current problem and security patches to address vulnerabilities or exploits and also improves the overall compatibility of NPM on your system. Here’s how to update NPM on your system:
1. Open the search bar on your PC, type Command Prompt, and press the enter key to open.
2. Type npm -v and press the enter key to check the current version of npm installed on your system.
3. If it shows an older version number, type npm install -g npm, and press enter. Now, your system will download and install the latest version automatically.
4. Verify the version using the npm -v command once the installation is complete.
2. Clear the Cache on Your System
Corrupted cached data can also be why the npm install command is not working on your computer. As cache stores data that an application uses frequently, and if the cache is corrupted, the data it sends to the application will also be incomplete or incorrect, causing the application to not run properly on your system. Here’s how you can clear the corrupted cache data on your computer:
1. Open Command Prompt on your computer.
2. Type the following command npm cache clean –force, press the enter key, and all the cached data for npm will be removed from your system.
3. If you’re using npm@5 or the latest version, then the cache for npm on your system can automatically heal itself from corruption issues, and you don’t need to run any commands.
Also, to check if everything is consistent with the cache, use the npm cache verify command.
3. Check and Install the Required Dependencies on Your System
Dependencies are modules or packages on which a project relies to work, and missing dependencies may cause interference with the project you’re working on.
To avoid problems with missing dependencies, you must ensure that all dependencies are specified correctly in the chúng tôi files and that they’re also installed successfully before running the project.
To install missing dependencies, navigate to the project directory, and use the npm install command with the dependency name.
4. Disable the Windows Defender Firewall
The Windows Firewall is a known culprit for causing issues with internet-related apps. A firewall can cause interference with the npm install in the following ways:
By Blocking Access to the Package Repositories: The npm install command retrieves packages from online repositories. If the firewall is blocking access to those repositories, npm may not download or install the dependencies/packages correctly.
By Blocking Access to the Local Network Resources: If you’ve configured NPM to install a package from a shared folder or network drive, and the npm install command is not able to install packages correctly, then there’s a chance that the firewall has blocked access to local network resources for you PC.
Apart from these, sometimes the firewall may block all the internet traffic coming to your PC, and in that case, the npm install command will fail as now it can’t connect to the internet to download the required dependencies.
There are two things that you can do to fix this issue. The first is temporarily disabling the firewall and checking if the npm install works. If it works, add npm to the exception list, and if it doesn’t, skip to the next step. Here’s how to disable the firewall on your computer:
3. Next, Select the Firewall & network protection option.
Once you’ve disabled the firewall, check if the npm install command is running, and if it’s running, add it to the exception list. Adding chúng tôi to the exception list:
1. Open the firewall & network protection menu and first enable the firewall.
5. Use a Different Network or VPN
If you’re using a protected network or an organizational WiFi and the npm install is not working, then there are chances that the ISP may have blocked npm installations. I’m also facing this problem with my university’s WiFi, where npm installation and MongoDB servers are blocked.
There are two solutions to fix this, the first is you should switch to another network on which repositories for npm installation are not blocked, and the second is if you can’t change networks, use a VPN to bypass the restrictions.
6. Disable Third-Party Antivirus Software
Some antivirus software may block NPM installations. Try disabling your antivirus temporarily and see if NPM works. If it does, you can add an exception to your antivirus settings for NPM.
7. Use NPM Install With -Force Option
If the above solutions don’t work, try using the npm install –force command. This command will force the installation process and may also fix all the issues related to the npm install not working on your computer.
8. Check NPM Registry
NPM Registry is a centralized database for packages and dependencies that a developer can install using the npm client. Whenever a dev runs the npm install command, the NPM establishes a connection with the registry to download all the required packages. NPM Registry is of two types: The public registry, which is the default one used by every NPM client, and the enterprise registry, which is a private registry of an organization.
9. Reinstall Node.js
If installing with the –force command doesn’t work, you should try reinstalling chúng tôi on your computer. A reinstall will replace all the corrupted files with fresh new files that will no longer give you errors. Here’s how you can reinstall chúng tôi on your computer:
1. Open the windows search bar, type Add or remove programs and press the enter key.
Now, perform a reboot to remove all the temporary files of chúng tôi from your computer.
1. Download and install the Windows installer from Nodejs.org.
2. Run the installer, follow the prompts, accept agreements, and install with default settings.
3. After the installation is complete, restart your computer.
NPM not working on Windows 11 can be frustrating, but there are several ways to fix it. Try the solutions above, and if none of them work, you can reach out to the chúng tôi community or the NPM support team for further assistance.
