How can I make flycheck use virtualenv
Thanks to an answer from Lunaryorn on github i realized there is also a flycheck-set-pylint-executable. Now all is working correctly whith the following configuration:
(defun set-flychecker-executables ()
"Configure virtualenv for flake8 and lint."
(when (get-current-buffer-flake8)
(flycheck-set-checker-executable (quote python-flake8)
(get-current-buffer-flake8)))
(when (get-current-buffer-pylint)
(flycheck-set-checker-executable (quote python-pylint)
(get-current-buffer-pylint))))
(add-hook 'flycheck-before-syntax-check-hook
#'set-flychecker-executables 'local)
Poking at the problem today, I found another solution (which works with current version of flycheck, as of Jun 2020).
Just create .dir-locals.el
with appropriate settings for given project. Like:
((python-mode
(flycheck-python-flake8-executable . "/home/marcin/.virtualenvs/adgv/bin/python")
(flycheck-python-pylint-executable . "/home/marcin/.virtualenvs/adgv/bin/python")))
(creating the file with M-x add-dir-local-variable
works too, but remember to add double quotes around the command)
