Cerebro: Error when start app

[pedroresende]

I am on the latest Cerebro.app version
I have searched the issues of this repo and believe that this is not a duplicate
Debian 9:
0.3.2:
Can't change settings

I still can get access to Cerebro by a shortkey but there are no icon in tray menu so i cant open devtool
If i try enable Developer mode by typing cerebro Settings i receive another error

Same error for me, on Fedora 28.

I'm getting two different startup exceptions. I installed cerebro_0.3.2_amd64.deb on Ubuntu 18.04.

Cerebro fails to launch on my system.

Exception 1

Uncaught Exception:
TypeError: Cannot read property 'webContents' of undefined
    at EventEmitter.module.exports._electron.ipcMain.on (/opt/Cerebro/resources/app.asar/main.js:687:47)

    at emitTwo (events.js:106:13)
    at WebContents.emit (events.js:191:7)

Exception 2

Uncaught Exception:
TypeError: visitor(...).screenview is not a function
    at module.exports.exports.screenView.screenName (/opt/Cerebro/resources/app.asar/main.js:251:15)

    at emitTwo (events.js:111:20)
    at App.emit (events.js:191:7)

Don't know if this helps, but other Electron apps such as Slack and Tusk are working fine for me.

0.2.8 ver works great on my Ubuntu 18.04 while 0.3.2 don't

[geraltofrivia]

I've had a similar error. I used 0.3.1 and recently deleted it (and stuff from .config/Cerebro before running the 0.3.2 Appimage. The trace goes like:

A JavaScript error occurred in the main process

Edit: I shifted to Manjaro today, running Deepin desktop.
In this installation, I haven't used 0.3.1 before, and directly tried running the latest version. I still can't get it working and encounter the same error.

[tioguda]

Hi, I can start the cerebro 0.3.2 after making the corrections below in my Manjaro Linux.

~/.config/Cerebro/config.json

Change the line
“trackingEnabled”: true,

for
“trackingEnabled”: false,

~/.config/Cerebro/config.json

Change the line

“positions”: {
      “1657191935228674”: [
          355,
          136
     ]
}

for

“positions”: {}

[geraltofrivia]

@tioguda thanks! This worked for me.

[zbin]

In my Linux Mint, I have a similar error. by deb package installed Cerebro.
I used the method provided by @tioguda, It's worked for me.

Not sure if related but getting this on cerebro startup (macOS Mojave)

[alabotski]

I have some error on mac 0.3.2

[qfox]

Why you using 0.3.2 (dec 17) when there is already 0.3.3 (may 18)?

I've just installed Cerebro via brew cask install cerebro and there are no 0.3.3, btw

[alabotski]

@zxqfox
Official size - https://cerebroapp.com/
Mac version - https://github.com/KELiON/cerebro/releases/download/v0.3.1/cerebro-0.3.1.dmg

Version 0.3.2

Where I can download 0.3.3?

[alabotski]

Is the project alive or dead?

[radiohazard-dev]

I have the same error.
Linux Distro: Ubuntu 18.04
Cerebro Version: 3.2
After "installing" the AppImage, I opened the app, and I got this error:

Uncaught Exception:
TypeError: visitor(...).screenview is not a function
    at module.exports.exports.screenView.screenName (/tmp/.mount_aZRaiX/usr/bin/resources/app.asar/main.js:251:15)
    at module.exports.exports.default (/tmp/.mount_aZRaiX/usr/bin/resources/app.asar/main.js:915:30)
    at App.module.exports._electron.app.on (/tmp/.mount_aZRaiX/usr/bin/resources/app.asar/main.js:653:43)
    at emitTwo (events.js:111:20)
    at App.emit (events.js:191:7)

I pressed OK on the error and the window closed and was replaced by another error:

Uncaught Exception:
TypeError: Cannot read property 'webContents' of undefined
    at EventEmitter.module.exports._electron.ipcMain.on (/tmp/.mount_aZRaiX/usr/bin/resources/app.asar/main.js:687:47)

    at emitTwo (events.js:106:13)
    at WebContents.emit (events.js:191:7)

I followed the instructions of @tioguda (albeit without the positions array, because I didn't have one) and was able to open the app, and went to the settings. I changed the theme to dark and then was faced with this error:

Uncaught Exception:
TypeError: Cannot read property 'settingsChanges' of undefined
    at EventEmitter.module.exports._electron.ipcMain.on (/tmp/.mount_KIlRaS/usr/bin/resources/app.asar/main.js:692:13)

    at emitTwo (events.js:106:13)
    at WebContents.emit (events.js:191:7)

I uninstalled the AppImage, deleted .config/Cerebro, and installed the same version as a .deb (in my GUI), where I was able to open the app but encountered the same issues.

[Conquistador]

Same errors...
Cerebro Version: 3.2
System: Win10

I think Cerebro is no longer developing.

Found for myself a new program on Mint

thanks, this worked for me.
