An ugly workaround could be using :python header argument to explicitly set the python path. Org babel uses a temporary buffer + `process-file' to evaluate code blocks with no session. The current directory is being set by let-binding `default-directory'. You can look into `org-babel-execute-src-block' (sets `default-directory') -> "(funcall cmd body params)" -> `org-babel-execute:python' -> `org-babel-python-evaluate' -> `org-babel-python-evaluate-external-process' -> `org-babel-eval' -> `org-babel--shell-command-on-region' -> `process-file' call chain and check where the envrc settings get lost. I am unsure how and why the Org's approach is not working together with envrc.el. It might be helpful to add envrc devs into the loop or debug things yourself. > Tangentially, if the block's header includes =:session=, as in > =#+begin_src python :session=, then the error is slightly different and > is displayed in the minibuffer as opposed to a separate buffer: > > #+begin_quote > make-process--with-editor-process-filter: Searching for program: No such file > or directory, python > #+end_quote This looks like "with-editor" package doing something funny.
