How to fix Failed to construct transformer:  Error: error:0308010C:digital envelope routines::unsupported by downgrading node version

When i checked my system i found that i have installed different node versions.I will list them down.

    19.6.0

  * 18.14.0 (Currently using 64-bit executable)

    17.0.1

    14.18.1

Out of above four versions,as mentioned above  18.14.0 is currently using.From node 17  onwards,there is  critical breaking changes.If i am using node 18.14.0 and running a react native project with old react native version 0.64.2 may leads to error.

So i fixed the error by downgrading my node version from 18.14.0 to 14.18.1. After downgrading error i could execute the command npm start sucessfully

How to fix Failed to construct transformer:  Error: error:0308010C:digital envelope routines::unsupported by the command  set NODE_OPTIONS=--openssl-legacy-provider 

If first option doesn't work or you are not willing to downgrade node version,then go with set NODE_OPTIONS=--openssl-legacy-provider command.Once you executed set NODE_OPTIONS=--openssl-legacy-provider command,then execute npm start ,your projct will work without any error

Thanks
