It freezed at 02:11:20.897, so I press ^C to interrupt.

Some possibly usable clues:

1. Firewall is not running.
2. I didn't encounter this problem on macOS.
3. 4000 port is not be occupied by others.
4. hexo is not installed system globally.

[tomap]

When it "freezed", did you tried to navigate at 127.0.0.1:4000 on your local browser ?

[kuanyui]

Yes, cannot open.

[RupGautam]

Why do you have node v6.9.x when it should be node v9.x.x ?
See hexojs/hexo#2534

[kuanyui]

1. I've tried rm -rf node_modules in my hexo repository then reinstall everything via npm install (Also tried to reinstall everything with yarn, but get same issue.)
2. I've tested this hexo repository could run under node v6.9.1 on my another system (macOS El Captain & High Sierra).
3. node v9.x.x seems incompatible with hexo 3.2.2, get lots of errors when run.
4. Surely, I always remember to rm -rf node_modules before changing the version of node via nvm use

[kuanyui]

I just try to use latest node.js LTS v8.9.4 carbon, hexo server still hang.......

Even add --debug to hexo server, nothing else special outputs...

And I don't know why npm ls --depth 0 gives me lots of ERR:

Hey @kuanyui , I tired node v. 8.x.x LTS on Arch Linux and I couldn't replicate the issue. I'm assuming it could be your system specific. Also, you sure you have nothing run on port that hexo is using?

Check it using netstat or something similar
$ netstat -na | grep -i LISTEN
$ netstat -f inet -na | grep -i LISTEN

Another check, I'm not sure if you have already done it.

• Create a test folder elsewhere
• Make sure the folder permission are correct or (at least 644)
• Then, hexo init and hexo server
• Also check this if it helps. npm installer runs into Err on ArchLinux hexo#2811

[kuanyui]

F-I-N-A-L-L-L-Y ! I found where the problem is!
See the screenshot, there's a symbolic link (I don't know how on earth it appeared at first), and this symbolic link has invalid target. rm this file, hexo server works.

I think this is a bug that should be fixed. I don't know what things hexo-server has done, but I've ever tried to use http-server to serve the same repository and encountered no problem like this.

Good job! But I'm not convinced it's related to HexoJS server tho.
Hey @NoahDragon, Can you look at this?
