Poetry-mode runtime error. env: unknown option --u

[anoduck]

It would be nice if you could define the poetry executable for this package, and/or how it is called. The full output of the error is:

env: unknown option -- u
usage: env [-i] [name=value ...] [utility [argument ...]]

This error arose from OpenBSD not using the gnu implementation of env, in which for gnu the -u flag is valid. Where as for the nongnu derivative of env, -u is not valid.

Adding an alias to my shell and see if that clears up the issue.

Hi!

Same error detected here, relevant bits here:

(let* ((prog (or (concat "env -i VIRTUAL_ENV " (executable-find "poetry"))
                     (poetry-error "Could not find 'poetry' executable")))

Working in a fix for this (and learning lisp in the process).

Edit: related with this commit: 93c9b24.

PR #48 is up, test the new code and verify if work correctly in your system. In my case, all is OK.

@yukiteruamano elisp is difficult, there is little doubt to that.

Whew...that was sketchy there for a minute. I haven't had to autoload a package in a while.

Still receiving the same error. poetry-error: [my project] Could not find ’poetry’ executable

If it helps, because OpenBSD is a bitch, you have to keep your distribution files pristine or bad things will happen. Also, since there is no package for poetry yet, this mean you have to perform a --user install. Which will place poetry in either ~/.local/bin/poetry or ~/.local/pipx/bin/poetry if using pipx. Both use the shell configuration file to add the bin folders to $PATH, which is why Emacs is experiencing difficulty resolving the path.

Where is your poetry bin file located? If it is the same as those mentioned above. Then I will need to work out why it is not finding it.

Hi!

Using OpenBSD 7.3-release here, my poetry bin is in $HOME/.local/bin/poetry

Doom Emacs updated and not problem with this change, detect Poetry VIRTUAL_ENV and don't show errors. Tested with waifu2x python version.

Edit: screencap.

[anoduck]

@yukiteruamano Well, that sucks. I am cleaning up my configuration after updating to 29.1, and going over any python variables. Will see if anything is uncovered.

Have you tried vanilla emacs?

[anoduck]

@yukiteruamano I really really really (that is three) appreciate you taking over maintaining this project. It plays such a vital role in development of python applications.

I know enough (or once did) ELisp to walk through the function of locating the poetry binary, which is what I will do, and see if I can get it to talk to me about hangups. In the meantime, I have enabled debugging and will post the debug output below.

My knowledge of Elisp is minimal, in fact, I am a new Emacs user, so the experience is not much.

However, let me reproduce this on other Emacs installations (Spacemacs, to be precise)

[anoduck]

@yukiteruamano I got it sorted...finally...I think... My (exec-path) is all buggered up, somehow. Thankfully, it works.

It Works!

[anoduck]

The error has returned, and it does not appear the previous method of designating a different means to activate poetry is no longer working.

The block of code begins on line 683, and is as follows.

(let* ((prog
	(or
	 (cond ((eq system-type 'gnu/linux)
                (concat "env -u VIRTUAL_ENV " (executable-find "poetry" t)))
               ((eq system-type 'berkeley-unix)
                (executable-find "poetry" t)))
         (poetry-error "Could not find 'poetry' executable")))
       (args (if (or (string= command "run")
                     (string= command "config")
                     (string= command "env")
                     (string= command "init"))
                 (cl-concatenate 'list (list (symbol-name command))
                                 args)
               (cl-concatenate 'list (list
                                      (symbol-name command)
                                      "-n" "--ansi")
                               args))))
  )

I am not sure if an update kicked out previous errors or what. Let me know how I can assists.

@anoduck What's your value of system-type variable?

You can check in your Emacs with describe-variable function.

@anoduck What's your value of system-type variable?

You can check in your Emacs with describe-variable function.

Fascinating stuff...

(describe-variable 'system-type)
#("system-type is a variable defined in ‘C source code’.

Its value is ‘berkeley-unix’

The value is a symbol indicating the type of operating system you are using.
Special values:
  ‘gnu’          compiled for a GNU Hurd system.
  ‘gnu/linux’    compiled for a GNU/Linux system.
  ‘gnu/kfreebsd’ compiled for a GNU system with a FreeBSD kernel.
  ‘darwin’       compiled for Darwin (GNU-Darwin, macOS, ...).
  ‘ms-dos’       compiled as an MS-DOS application.
  ‘windows-nt’   compiled as a native W32 application.
  ‘cygwin’       compiled using the Cygwin library.
  ‘haiku’        compiled for a Haiku system.
Anything else (in Emacs 26, the possibilities are: aix, berkeley-unix,
hpux, usg-unix-v) indicates some sort of Unix system.

  Probably introduced at or before Emacs version 19.31.

Emacs is beautiful, isn't it?
