@PitaJ I think you fucked up, clean pull from master...

EDIT:
I rearranged the requires so the require('../../require-main'); is last:

var fs = require('fs');
var path = require('path');

var packageInstall = require('./package-install');
var dirname = require('./paths').baseDir;

require('../../require-main');

Seems to work.

EDIT2:
maybe not

@PitaJ said in Setting up a local environment of nodebb causes some weird errors from dbsearch:

Changing dbsearch mongodb search schema to use _id fails · Issue #49 · barisusakli/nodebb-plugin-dbsearch

Fixed in latest master

awesome, thanks!

I'm installing nodebb just fine, however when I enable nodebb-plugin-dbsearch, it says my NodeBB schema is out of date and I need to update it with nodebb upgrade. Sure no problem, however when I run the upgrade command it spits out an error saying Error: Cannot find module './database'. Uhh, what? I've deleted everything (and dropped the db) several times without luck.

@pitaj Thank you for the detailed answer, appreciate it!

I want to create a new privilege for categories.
I'm not quite sure how to go forward with this idea. What I've done so far is:

var privileges = module.parent.require('./privileges');
privileges.privilegeLabels.push({ name: '[[admin/manage/privileges:custom]]' });
privileges.userPrivilegeList.push('topics:custom');

Now what do I do? The above code creates a new column in the privileges table, but no clickable checkboxes.
Where do I write the logic for the custom privilege?
I want the plugin to filter topics in categories based on the privilege of users.
I also find the source code very confusing, no JSDoc or any other comments.
