Hi @nikaspran, I follow this article but got permission error for this file .platform/hooks/prebuild/yarn.sh. How and where I should do chmod +x to this file?

make sure you add the correct version:

sudo curl --silent --location https://rpm.nodesource.com/setup_{version_number}.x | sudo bash -

@hmtri1011

for permission, git update-index --chmod=+x path/to/file

2 things I would like to add:

  1. after git update-index command, you only have to git commit
  2. touching /path/to/file is always resetting the permission for me from 100755 => 100644. So I have to make sure I run update-index command again
