Lsp-mode: Error: cond: Symbol’s value as variable is void: method

[stapelberg]

Describe the bug
lsp-mode prints an error message:

LSP :: Connected to [gopls:21956 status:starting].
error in process filter: cond: Symbol’s value as variable is void: method

…and in general does not seem to work. E.g. running M-x lsp-find-definition results in Lisp error: (void-variable check-command)

To Reproduce

1. Install lsp-mode-20190415.853
2. Install https://github.com/golang/go/wiki/gopls: go get -u golang.org/x/tools/cmd/gopls
3. Configure lsp-mode to use gopls as per https://github.com/golang/go/wiki/gopls
4. Enable LSP mode while working on a .go file.

[stapelberg]

This was solved by updating the dash package to version 20190413.1058.

I do wonder why lsp-mode lists dash 2.14 as a requirement, though, and I’m using 20190413.1058, not 2.14.

Am I missing something about how emacs package version numbers work, or could lsp-mode’s requirements be improved to pull in this dependency automatically? This was a fresh installation of lsp-mode.
