Morning, recently I tried to use ob-go and ran immediately into: org-babel-execute:go: Invalid function: (results (org-babel-eval (format "%s run %s \"%s\" %s" org-babel-go-command (mapconcat (quote identity) (org-babel-go-as-list flags) " ") (org-babel-process-file-name tmp-src-file) (mapconcat (function (lambda (a) (format "%S" (if (symbolp a) (let* (... ...) (if ... ... out)) a)))) (org-babel-go-as-list args) " ")) "")) The strange thing is, that this only happens on my Mac. On my CentOS machine it works like a charm. Both machines run on Emacs 26.1b1 and org mode 9.1.9-65-g5e454. All packages are from Melpa and the machines share the same .emacs. I have no idea how to get to the bottom of this phenomenon. Any hint or help would be appreciated very much. Thank you Mario —
