Updating vue-cli shouldn't have any effect on the project code -- it's just for templating.
What OS is your project on? Is the project in a folder with any special settings that could interfere with operating system events (e.g., Dropbox folder)?
I had the same problem, except it somehow affected all my projects (fresh installs and existing).
I'm running Fedora 25 and node v6.11.2
I'm not sure what the actual problem was, but I managed to fix it. I'm a bit surprised this works:
yarn installAnd now it works. Reinstalling all dependencies with npm didn't work, so it must be doing something wrong...
Actually this issue has reappeared. The fix this time is mentioned in a comment in #378.
Adding the following to the webpack-dev-middleware config solved the issue this time:
watchOptions: {
aggregateTimeout: 300,
poll: 1000
}
I changed in config/index.js, under dev from poll: false to poll: 1000, and that worked too
geniass's solution (with using yarn) works for me properly
