It’s something weird, but from last week :observer.start is not working in my machine. This is the error that I’m receiving: Erlang/OTP 20 [RELEASE CANDIDATE 2] [erts-9.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false] Interactive Elixir (1.4.4) - press Ctrl+…

Many thanks, @l00ker that worked for me too. Curiously I have installed 1.9.3.6 at first, but it doesn’t work either. After that, I have downgraded the package one more time, to version 1.9.3, and now it’s working. Thanks to everyone for your help.

Has anyone else been able to resolve this problem with OTP 20/Elixir 1.5? I get the identical error, with the same version numbers for wx-1.8.1 and “version WXU_3.0 not defined in file…” on Linux Mint 18.

It’s working for me with that configuration on Ubuntu. Have you tried to downgrade your OTP version? That worked for me with 1.19.

I can do that. I was curious if there was a fix for OTP 20

Hi everyone, I am using ubuntu 14LTS and this worked for me on both OPT20 Elixir 1.4 and Elixir 1.5: apt-get install libwxgtk3.0-0 But my error was: {:load_driver, 'libwx_gtk2u_stc-3.0.so.0: cannot open shared object file: No such file or directory'} Anyway I hope it can help some of you !

Unfortunately, it looks like it still doesn’t work on Mint. It’s possible that I installed a stray dependency that needs to be cleared out. Erlang/OTP 20 [erts-9.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false] Interactive Elixir (1.5.1) - press Ctrl+C to e…

Well if your Erlang was RC, it’s not anymore so that’s something [image] GregFreeman: I get the identical error, with the same version numbers for wx-1.8.1 and “version WXU_3.0 not defined in file…” on Linux Mint 18. this was the RC error, now you get “WX Failed loading” [image] GregFree…

I am also running Linux Mint 18.1 Serena, and I have been able to get Erlang/OTP 19 with :observer-support installed using the ASDF version manager, by following the ‘before install’ steps here , so maybe that helps :slight_smile:

Installing libwxgtk3.0-0-dev helped me

:observer.start is not working on Ubuntu
