I just tested installation of NodeBB on fresh OS and its working. There have to be something wrong with my OS.

Yesterday NodeBB installation was successful, today i have this error:

> cd rust/benchpress-rs && npm install

When again trying to reinstall NodeBB from the begining i got similar error

And installing again.

And again.

Now NodeBB shows:

I just wonder how yesterday everything was working well and now i cant install NodeBB. I'm stuck and don't know how to go further.

My goal is to connect NodeBB to MongoDB only with unix socket.
Found here that is possible to use unix socket with mongodb, also this link was helpfull but can't figure out how to solve this error.

Why "error: failed to connect to server [%2Ftmp%2Fmongodb-1033.sock:27017]" there is default 27017 port, whats missing in this config?

{
    "url": "http://www.example.net/forum",
    "secret": "secret",
    "database": "mongo",
    "port": [

    "mongo": {
        "uri": "mongodb://user:pass@%2Ftmp%2Fmongodb-1033.sock/db_name",
    }   
}

Just checked this site and all mixed content are only images, couldn't find ttf. Anyway its just a warning that images are not going trough https.

No mater what i do, got the same error.

cat test.js
var nconf = require('nconf');
nconf.file({file: "config.json"})
var db = require('./src/database');
db.init();
var u = require('./src/user'); // This triggers the error

$node test.js

Im using: nodeenv (1.0.0) inside vierualenv (15.0.3)
NodeBB 1.4.0
Node 6.0.0
npm 3.8.6

$node debug test.js

break in module.js:419
417   } finally {
418     if (threw) {
419       delete Module._cache[filename];
420     }
421   }

I think i found the solution but don't know how to apply it.

use node 5.x instead of node 6 // Tried it, same result.
or
add a key 'publicPath' to the webpack config output node
output:{
publicPath:''
}

I don't know where to add publicPath.

@baris Hm was doing similar approach, please check my another question with path.js error.

I am writing a small program in python to remove bots from forum. Learning node.js and redis from about 2 days from now on but couldn't figure it out how to use build in module nodebb/src/posts/delete.js Posts.purge.

So my question is, is it possible to remove user and all its content from command line?

All my tries failed, and I am not sure how code suppose to look like.
