Can anybody provide help here? @friederbluemle @krunalsshah

[friederbluemle]

Hi @IndianNative and @dig22 - Would you be able to test using version 0.38.16 and let us know if you're still seeing the same issue?

ern platform use 0.38.16

Also, just checking: How did you install the Electrode Native CLI (e.g. using npm or Yarn)?

[IndianNative]

Hi @friederbluemle thanks for your response - Also I tried using version 0.38.16 but no luck.

Also I installed it using npm.

[krunalsshah]

Thanks for writing back. I believe you are using Win OS. Please confirm your node version. For curiosity sake please let us know the yarn version. Try running the command with ERN_LOG_LEVEL=trace & past the logs. thanks

It appears to be an issue with spawn.. Can you also try to use bash for WSL?

[IndianNative]

Hi @krunalsshah .Yes I am using Win OS,. My current versions are
electrode-native: 1.0.17
ern platform: 0.38.16
node version - 9.1.0
react-native-cli: 2.0.1

[IndianNative]

Hi @friederbluemle , tried git bash for the same but not solved.

[friederbluemle]

Are you able to create a regular React Native app?

npx react-native init test

[IndianNative]

Ye I am able to create it successfully -

Hi @krunalsshah I tried using ERN_LOG_LEVEL=trace and found the logs:

@friederbluemle I tried using WSL (ubuntu 18.04) it works but gives another error mentioned below:

Command yarn add react-native@0.60.6 --exact failed.

(However unrelated to this issue i think)

This issue is only with respect to windows : cmd/powershell gets stuck on running the command and git-bash gives a spawn error.

[Windows]
electrode-native : v1.0.17
ern platform : v0.39.0
node : v12.14.1

[WSL Ubuntu 18.04]
electrode-native : v1.0.17
ern platform : v0.40.0
node : v12.16.1

Thank you for assistance and WSL workaround @IndianNative @friederbluemle @krunalsshah

[friederbluemle]

Thanks for reporting back @dig22 - Is there any additional output for the other error you're seeing?

[dig22]

@friederbluemle unfortunately no other log info apart from what @IndianNative found on git bash.

PowerShell gets stuck here :

[friederbluemle]

@dig22 - Thanks for the screenshot. I have a Windows machine ready for testing and will check this either tomorrow or on the weekend (quite busy with work at the moment, so apologies for the delay).

[friederbluemle]

@dig22 @IndianNative - The issue is reproducible and we're looking into it. Will update you on the progress.

[friederbluemle]

@dig22 @IndianNative - Electrode Native version 0.40.2 was released just a couple of hours ago. It contains a fix related to running Yarn on Windows.

Can you please try again using the latest version:

ern platform use latest

Then, repeat the same command you used above.

ern create-miniapp app

[IndianNative]

Thanks @friederbluemle will check with latest version and update you soon. I was also occupied with other work so didn't get time to check this thread.

[friederbluemle]

Hi @IndianNative - Just checking real quick if you've had a chance to test it again with the latest version of ERN?
