* jedi_vim.jedi_import_error: add location This is useful for debugging. It contains e.g. the path to parso, if importing failed from there. Example: > Error: jedi-vim failed to initialize Python: jedi#setup_python_imports: could not import jedi: cannot import name 'PythonTokenTypes' (in /…/jedi-vim/pythonx/jedi/jedi/api/completion.py:1). (in function jedi#init_python[3]..<SNR>44_init_python[27]..jedi#setup_python_imports, line 37) * init: handle jedi_vim.jedi_import_error in Vim plugin Using `set shortmess+=F` would suppress the `:echom` used in `jedi_vim.no_jedi_warning` [1]. This patch makes `jedi#setup_python_imports` handle the error instead. 1: https://github.com/neovim/neovim/issues/8675 * Revisit error handling with loading jedi_vim * jedi#debug_info: display parso submodule separately * Fix jedi#reinit_python * fixup! Revisit error handling with loading jedi_vim * display_debug_info: handle exceptions with environment.get_sys_path * fixup! Revisit error handling with loading jedi_vim [ci skip]
