Stopped working in Slack 4.0

[bauerp]

Apparently Slack made some changes which doesn't allow this to work anymore. Hope that you can fix this.

I get the following:

~/ sudo slack-theme night
file does not exist

[Dumberdore]

Please check this comment Following worked for me (I am using ZSH - Please check install section for other shells)-

$ sudo slack-theme uninstall
$ curl https://raw.githubusercontent.com/mykeels/slack-theme-cli/master/slack-theme -O && SLACK_THEME_SHELL_PROFILE=~/.zshrc bash slack-theme install && . ~/.zshrc
$ slack-theme night
$ slack-theme midnight-blue

Would you please check ?

[xxKeith20xx]

@OkBeacon I just tried it w/ zsh and it seems to run, but still shows the default slack theme for me?

[mykeels]

@OkBeacon, I'm glad it works for you.

@xxKeith20xx, are you saying no matter what slack-theme command you run, only the default white theme shows?

[xxKeith20xx]

I tried again and now slack fails to open with this error:

A JavaScript error occurred in the main process:

After reinstalling and starting fresh, the issue seems to be that no matter what slack-theme command I run, only the default white theme shows @mykeels

[guhanrv]

I get "no matching processes belonging to you were found" and it opens up normally.

[bauerp]

I got it to work using OkBeacon's method. Thanks!

[ransagy]

Anyone managed to get it working in Windows/WSL? Just can't seem to get it to run properly.

[mykeels]

@ransagy I hope to spend sometime this weekend getting it working for Windows

[kevcenteno]

This is broken on linux as well.

[kishore-vkrn]

tried steps by @OkBeacon still loading with default white

[bauerp]

Using OkBeacon's method works for me initially, but after a day or two it automatically reverts back to the default theme while still being on the same Slack version. This is happening on both my Macs.

[kkuhle]

+1 on WSL

[dubhunter]

Bump

My experience has been the same, worked nicely for a short while.

I installed for the first time. No themes worked. Tried: slack-theme uninstall: the running Slack quit. Starting it back up: A JavaScript error occurred in the main process

The file: Applications/Slack.app/Contents/Resources/electron.asar/browser/init.js doesn't exist: electron.asar is a file, not a directory.
