pyvenv-workon command does not list available environments in Ubuntu 22

[ankitvyn]

Virtualenvwrapper was installed using pip install --user virtualenv virtualevnwrapper.

The problem is reading the list of available virtual envs. Below is the code snippet which does this.

(defun pyvenv-virtualenv-list (&optional noerror)
  "Prompt the user for a name in $WORKON_HOME.

If NOERROR is set, do not raise an error if WORKON_HOME is not
configured."
  (let ((workon-home (pyvenv-workon-home))
        (result nil))
    (if (not (file-directory-p workon-home))
        (when (not noerror)
          (error "Can't find a workon home directory, set $WORKON_HOME"))
      (dolist (name (directory-files workon-home))
        (when (or (file-exists-p (format "%s/%s/bin/activate"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/bin/python"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/Scripts/activate.bat"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/python.exe"
                                         workon-home name)))
          (setq result (cons name result))))
      (sort result (lambda (a b)
                     (string-lessp (downcase a)
                                   (downcase b)))))))

As of now the activate script is located in $WORKON_HOME/env_name/local/bin/. Can be fixed with adding /local in the above codepath.

(defun pyvenv-virtualenv-list (&optional noerror)
  "Prompt the user for a name in $WORKON_HOME.

If NOERROR is set, do not raise an error if WORKON_HOME is not
configured."
  (let ((workon-home (pyvenv-workon-home))
        (result nil))
    (if (not (file-directory-p workon-home))
        (when (not noerror)
          (error "Can't find a workon home directory, set $WORKON_HOME"))
      (dolist (name (directory-files workon-home))
        (when (or (file-exists-p (format "%s/%s/local/bin/activate"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/local/bin/python"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/Scripts/activate.bat"
                                         workon-home name))
                  (file-exists-p (format "%s/%s/python.exe"
                                         workon-home name)))
          (setq result (cons name result))))
      (sort result (lambda (a b)
                     (string-lessp (downcase a)
                                   (downcase b)))))))
