[friederbluemle]

Hi @chc7042 - Yes, it looks like there is a problem constructing the path.. Can you provide some more details about your environment? Which Windows version are you running? Are you using the command prompt or powershell/bash? Also, please provide exact repro steps (i.e. which ern commands did you run to produce the error in the first post?).

[chc7042]

Hi @chc7042 - Yes, you're right, there has been an issue with this miniapp for a while. Sorry for the confusion. Can you please try the following repo instead and see if you can get it to run:

Hi @friederbluemle basically i wnat to know that i am planing to architect make main application with micro app (such as minApp) micro app means that it can be installed to main application (just like module of component) and remove that later time. so this could be architected from electrode natie i think. so i really want to execute this sample application. i thnk you are very busy.. but please help me

[chc7042]

Hi @friederbluemle @anthonywebb @martnu @IgorGanapolsky is there no way to solve problem? i thnk your walmart has an own solution about this. please let me find clue for solve this issue

[chc7042]

Hi @friederbluemle i hope to know the your enviroment of pc expecially node, and yarn version including which OS are you using. based on your comment i will try it again... in advance thank you..

[friederbluemle]

Hi @chc7042 - My default environments on both Linux and macOS always include the latest stable tool versions: Node.js 15.11.0 and Yarn 1.22.10 Most React Native developers at Walmart are using macOS. I will try to run some tests on my Windows test machine when I have some time (I'm currently swamped unfortunately). The error you described appears to be related to: https://stackoverflow.com/questions/58117377/react-native-start-giving-invalid-regular-expression-invalid-error As a workaround, could you try using Node.js version 10 on your machine?

[chc7042]

Hi @friederbluemle i tried to change nodejs version using nvm as below D:\ADT\Workspace\weather\weather_expo>nvm list 14.16.0 12.10.0

• 12.0.0 (Currently using 64-bit executable) 11.0.0 10.0.0 8.10.0 8.9.4 result is as same as previous. so i tried to install ubuntu and let you know result. always thank you for your help

[chc7042]

Hi @friederbluemle Based on your comment. i finally solve this problem after install ubuntu 18.04 and node 14.16, yarn latest. then here is no error message and i could run movies-reloaded-miniapp thank you for you help. i will try to look into this project

[chc7042]

Hi @friederbluemle after execute reload project on android emulator. i can't understand that it is working way. because https://github.com/electrode-io/movielist-miniapp.git already has mainMiniApp and miniapp without ern run-android without any argument. so i tried to learn from git reference site but it really difficult could you share the information about how does it works? https://github.com/electrode-io/movielist-miniapp.git

is there a way(or example) to know whole architecture of electrode native? in advance thank you for your help

[friederbluemle]

I'm not sure I understand the question.. When you only run a single miniapp, then mainMiniApp is not required (because there is only one). You only need mainMiniApp when starting multiple miniapps.

The best place to learn about the architecture and terminology of Electrode Native are the docs: https://native.electrode.io/

Syntax/arguments for run-android: https://native.electrode.io/cli-commands/run-android#syntax

[chc7042]

Hi @friederbluemle thank you for your reply. what i want to know is that at first

1. i follow the direction based on https://github.com/electrode-io/movielist-miniapp
2. execute ern run-android without addition argument (it means that standalone execution)
3. now i hope to see the detailed page using addition argument (ern run-android --miniapps moviedetailsminiapp --mainMiniAppName MovieListMiniApp) but it does not work finally i can't see detailed page even though touch list item) so i want to know wehere is the detailed miniapp located? i am following this page https://github.com/electrode-io/movielist-miniapp

i think if i want to invoke detailesminiapp with mainlistapp then git url should be changed to https://github.com/electrode-io/MovieDetailsMiniApp.git but readme indicate https://github.com/electrode-io/MovieListMiniApp.git

how does it invoke MovieListMiniApp is it possible to just add argument such as --miniapps moviedetailsminiapp ?
