File mode specification error: (void-variable get-root)

[edmz]

Using latest lsp-mode from Melpa, running Emacs pretest 26.0.91.

I get said error while the language mode hook tries to run the enable function, in my case its #'lsp-elixir-enable and also with ruby.

Same issue here on python. Emacs 26 and latest Melpa build.

Does #296 work for you?

[casouri]

Maybe I did something wrong? It didn't fix it for me.

I made according changes in lsp-mode.el, recompiled it and regenerated autoloads.

Cannot reproduce this here. Have you tried re-compiling/re-installing both the language client package and lsp-mode?

[edmz]

I made the change, restarted emacs and it worked. Now I am getting another error when I try to run lsp-capabilities: "Wrong type argument: hash-table-p, nil". But that could be something else.

@vibhavp This issue recurs on my computer 100%.

Here is the test code: https://gist.github.com/twlz0ne/38f9f972574abcb860ee06c33398ee97

Just 1)Download 2)Run.

FWIW, experienced this in syl20bnr/spacemacs#10391. Fixed it as in #296 plus

re-compiling/re-installing both the language client package and lsp-mode

[vv111y]

Not working in spacemacs, my backtrace and config info is here syl20bnr/spacemacs#10449

I removed python and lsp layers and then reinstalled (this removes and reinstalls all relevant packages). No change. No compile errors either.
