[Vuejs]-Npm install failed, could be a network problem?

No, It couldn’t be a network problem.
You can try some cleaning methods. First of all try

npm cache clean --force

Then try to delete Node modules folder and then reinstall it:
(first of all, check if you have some components or CSS you edited before delete your node folder)

• delete node_modules folder
• delete package-lock.json file
• npm install

Now you cant try to npm run dev / npm run serve again
