TypeError: FileSystemCardStore is not a constructor

i’m getting this error.
Did any one solved this error??

My composer version is v0.20.1

Yes I think in the new version of composer we dont have this. My Article is for composer 0.17.6

Hello @Varun,
Do you have any other solutions for solving this??

You just need to use the class which is alternative FileSystemCardStore in latest version.
