I’m having trouble with a MEAN 2.0 project I’m working on. Everything went smoothly when I ran npm install in the server folder. But when I tried to do the same in the client folder (Angular 2 part), I hit a snag.
The error messages are all about connection problems. It looks like the system can’t reach the DefinitelyTyped repository to download some type definitions. Here’s a snippet of what I’m seeing:
typings ERR! message Unable to read typings for "jasmine". You should check the entry paths in "jasmine.d.ts" are up to date
typings ERR! caused by Unable to connect to "https://raw.githubusercontent.com/DefinitelyTyped/DefinitelyTyped/c49913aa9ea419ea46c1c684e488cf2a10303b1a/jasmine/jasmine.d.ts"
typings ERR! caused by connect ECONNREFUSED 10.10.34.36:443
I’ve tried running npm install both with and without a proxy, but no luck. It seems like the issue is with typings. Any ideas on how to fix this? I’m using Node v6.9.1 and npm v4.0.1.
Should I try updating Node or npm? Or is there something else I’m missing? Thanks for any help!
Have you checked your Node version compatibility with Angular 2? Sometimes, outdated Node versions can cause peculiar issues. Consider upgrading to a more recent LTS version of Node.
Another thing to try is clearing the npm cache and deleting the node_modules folder, then running npm install again. This often resolves dependency-related problems.
If the issue persists, you might want to look into your network settings. Some users have reported success by changing their DNS server to Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1).
As a last resort, you could try installing the packages one by one, which might help identify the problematic dependency. It’s time-consuming but can be effective in pinpointing the issue.
hey mate, sounds like a pain! have u tried clearing ur npm cache? sometimes that helps. also, check ur firewall settings - they might be blocking the connection. if all else fails, u could try manually downloading the typings and adding them to ur project. good luck!
I’ve run into similar issues before, and it can be quite frustrating. One thing that worked for me was switching to a different network. Sometimes corporate or public Wi-Fi can cause these connection problems. If possible, try using your mobile hotspot or a different internet connection altogether.
Another approach that might help is temporarily disabling your antivirus software. In some cases, overzealous security programs can interfere with npm’s ability to download packages.
If those don’t work, you could try using yarn instead of npm. It’s an alternative package manager that sometimes handles network issues better. Just install yarn globally and then run ‘yarn install’ in your project directory.
Lastly, if nothing else works, consider setting up a local npm registry mirror using tools like Verdaccio. This can help bypass network issues by serving packages from your local machine.
