I encountered an issue while trying to install Hardhat using npm in my Visual Studio Code project. When running the command:

"npm install --save-dev hardhat"

An error message is displayed:

npm ERR! code ERR_INVALID_URL
npm ERR! Invalid URL

npm ERR! A complete log of this run can be found in: C:\Users\jawad\AppData\Local\npm-cache\_logs\2023-09-12T21_20_59_996Z-debug-0.log

Despite attempting various solutions like clearing the npm cache, checking internet connection, and changing npm registry, the issue persists. Can someone help me understand why this error is occurring and how to fix it?

Thank you for your guidance!

I tried to add Hardhat to my Visual Studio Code project by executing the following npm command: npm install --save-dev hardhat

Here are the steps I took, the expected outcome, and what actually happened:

What I Did: I followed the suggestions provided previously, such as clearing the npm cache, verifying internet connectivity, switching npm registries, and updating npm.

Expected Outcome: I anticipated that the command npm install --save-dev hardhat would successfully install Hardhat and its dependencies without errors, with a confirmation message indicating successful installation.

Actual Result: Instead, I received the following error message:

npm ERR! code ERR_INVALID_URL
npm ERR! Invalid URL

npm ERR! A complete log of this run can be found in: C:\Users\jawad\AppData\Local\npm-cache\_logs\2023-09-12T21_20_59_996Z-debug-0.log

Answer №1

The root of this problem typically lies in the configuration settings or NPM's inability to process requests.

To verify the available registry, execute the following command:

npm config get registry

You can also consider adding a .npmrc file to the project directory:

https://i.sstatic.net/NsQOr.png

registry=https://registry.npmjs.org/
                        
always-auth=true

If the URL https://registry.npmjs.org/ is valid and accurate, ensure to inspect your network setup (including any proxies) for potential blocks on https://registry.npmjs.org/ due to network constraints.
