How to Resolve npm install Stuck at ‘idealTree’ Step and Troubleshooting common npm installation issues in Express on Ubuntu? | Projectshop

When you encounter issues with installing Express (or any npm package) that seem to get stuck at the idealTree step, it often points to problems with your network issues, npm setup, or package dependencies. Here are some steps to troubleshoot and resolve this issue:

1. Network issues:
i) Check, change and refresh your internet connection (WiFi or cellular).
ii) Reboot/restart your system.
iii) If you suspect network problems, you can use a tool like npm doctor to check for network connectivity issues.

npm doctor

2. Clear npm cache: Sometimes, a corrupted npm cache can cause installation problems.

npm cache clean --force

3. Update npm: Ensure you have the latest version of npm installed.

npm install -g npm

for windows try: npm update -g npm

4. Delete node_modules and package-lock.json: Remove existing node_modules and package-lock.json to ensure a fresh installation.

rm -rf node_modules package-lock.json

5. Try installing again: Attempt to install the packages again after clearing cache and removing node_modules.

npm install

6. Check your package.json for issues: Sometimes, conflicts or errors in the package.json file can cause installation issues. Ensure there are no errors or version conflicts in your package.json.

7. Use a different registry: You can try switching to a different npm registry temporarily to see if it’s a registry issue.

npm config set registry http://registry.npmjs.org/
npm install

8. Try using Yarn: Sometimes, using a different package manager like Yarn can help bypass npm-specific issues.

npm install -g yarn
yarn install

On following these steps can help in diagnosing the npm installation problem.
