Why vue mobile terminal project in hbuilderx packaged into the app, the same project version number 1.8.10 and 1.8.11, respectively installed first again after 1.8.10 1.8.11 prompts system exists high version could not be installed? Repackaged into 2.1.0 cannot install will be prompted to remain higher version, but empty vue program were packaged into 1.8.10 and 1.8.11 can upgrade installation? Vue project carried out before the normal upgrade installation is no problem, please everyone a great god, and this is what reason, please comment, thank you!
