Nodejs deta-micros Problem on installing dependency on deploy

[Pabluskagamo]

Hello guys i have a problem on deploying my api. There is a module that is not getting installed on deploy because this module downloads a tar file from a git reposity but when it tries to unzip it fails because tar is not a valid command in the micro. I think it is because tar is not installed in the machine. Im getting the following error:

$ deta deploy

I dont know if there is a different way to install this module. I hope you can help me.

Thank you for your atention.
