Same here. For reference, here's the error I receive when updating the config.js file:

upgrade to node 14.x fixed this issue for me.

[coffeephile]

I tried updating to Node 14.x on Windows 10, but still no luck.

Light hot reload (markdown hot reload) works fine, but deep hot reload (config.js changes, frontmatter changes) gets stuck on the terminal and I don't see the updates on the site.

No issues on Mac though.

Following up on this. Have same issue.

[SimZhou]

Same here.

update1: Tried upgrading node from v10 to v12, still.

update2: watchpack v1.6.1, v1.7.2, both not working.

update3: Changed my directories by removing special characters (my project dir has dots and spaces), still.

update4: tried vuepress v1.5.1, 1.5.2, still.

update5: I got it Solved!

By running the local server with option --temp .temp!

Specifically, in package.json, substitute:

"dev": "vuepress dev docs",   

with

"dev": "vuepress dev docs --temp .temp",   

This creates you a temporary folder ".temp" for your dev server.
If you don't want this to be pushed to your remote repo, just add this folder name in your .gitignore file.

It works for me, not sure if it works for you as well.

@SimZhou Not working for me. Tried your ``temp fix but after reloading, it goes blank.

Might have posted to wrong issue, but I have issues with frontmatter not hotloading..

Not working for me either. I've tried all the fixes. None of them work. I think there may be more than one issue that are only loosely related.
