It looks like you encountered the npm error code ERR_INVALID_URL while trying to remove a proxy configuration using the command `npm config rm proxy`. This error signifies that the URL provided is invalid in the context of npm configuration. To tackle this issue, here are a few steps you can take: 1. Check the Proxy URL : Ensure that the URL you are trying to remove is correctly formatted and valid. Even a small error in the URL can trigger the ERR_INVALID_URL error. Double-check the proxy URL in your npm configuration settings. 2. Verify npm Configuration : Run `npm config list` to review all your npm configurations, including the proxy settings. This command will display all the npm configurations set on your system, allowing you to identify any discrepancies or invalid URLs. 3. Remove Proxy Configuration : If the URL seems correct, you can try explicitly setting the proxy URL to null instead of removing it. Use the following command: npm config set proxy null npm config set https-proxy null 4. Update npm : Ensure your npm version is up to date. Sometimes, updating npm to the latest version can resolve such issues. You can update npm using: npm install -g npm 5. Clear npm Cache : If the problem persists, clearing the npm cache might help. Run the following command to clear the npm cache: npm cache clean --force 6. Debug Log : Lastly, review the debug log mentioned in the error message (C:\Users\DGP1PLK\AppData\Local
pm-cache\_logs\2025-03-04T04_28_27_438Z-debug-0.log). It can provide more detailed information on what went wrong during the npm configuration removal process. By following these steps and ensuring that your proxy URL is correctly configured or set to null if needed, you should be able to resolve the ERR_INVALID_URL issue. If the problem persists, reviewing the debug log will offer more insights into the root cause of the error. I hope these suggestions help you resolve the npm ERR_INVALID_URL error effectively! If you have any more questions or need further assistance, feel free to ask.

Proxy Settings : If you are behind a corporate proxy, ensure that the proxy URL is correctly formatted (e.g., http://proxy.example.com:8080 ). The ERR_INVALID_URL error is likely caused by a malformed proxy setting in your npm configuration. By manually editing the .npmrc file, clearing the npm cache, and ensuring proper proxy settings, you should be able to resolve the issue and successfully install TypeScript.

Step 1: Check Current npm Configuration Run the following command to view your current npm configuration: npm config list This will display all npm settings, including global and user-specific configurations. Look for any proxy-related settings such as: proxy https-proxy strict-ssl If you see any invalid or malformed URLs (e.g., missing http:// or https:// ), note them down for correction. Step 2: Manually Edit the npm Configuration File If the npm config rm proxy command fails, you can manually edit the npm configuration file to remove or fix the proxy settings. Locate the npm configuration file: For global settings: %AppData%
pm\etc
pmrc (Windows) or /usr/local/etc/npmrc (Linux/Mac). For user-specific settings: %UserProfile%\.npmrc (Windows) or ~/.npmrc (Linux/Mac). Open the .npmrc file in a text editor: notepad %UserProfile%\.npmrc or notepad %AppData%
pm\etc
pmrc Look for lines containing proxy , https-proxy , or strict-ssl . If they exist, delete them or correct their values. For example: proxy=http://your-proxy-url:port https-proxy=http://your-proxy-url:port strict-ssl=false If you don't need a proxy, simply remove these lines.

The error you're encountering ( ERR_INVALID_URL ) while trying to remove the proxy configuration using npm config rm proxy suggests that there might be an issue with your npm configuration or environment. The error ERR_INVALID_URL indicates that npm is attempting to process a URL, but it encounters an invalid format. This could be due to a misconfigured proxy setting in your npm configuration. The command npm config rm proxy is used to remove the proxy configuration from npm settings. However, if the proxy value is already malformed or improperly set, npm may fail to process it. Your Node.js version ( v18.20.7 ) is compatible with modern npm versions, so this is unlikely to be the root cause.
