Test Validator bzip2 error

When trying to start test validator on win10, I get the following error:

“ERROR solana_ledger::blockstore] tar stderr: tar: Can’t launch external program: bzip2”

Full output is:

Hi @ijuedt and welcome to the forum!

It sounds like you need to install bzip2, or you could install the Solana CLI inside of a WSL ( Windows Subsystem for Linux ) shell instead, which will come with bzip2.

I would probably recommend using WSL.

Let me know if you have any other questions about it!

Hi @zicklag ,

thanks for your reply! I’ve already deployed bzip2, maybe it’s only a matter of configuring solana to use it - for this, I didn’t find documentation, maybe I overlooked soomething. As far as possible, I’d like to keep my Windows deployment as other parts of my installation run already well and I’m not that much used to a Linux environment.

Fair enough. :+1: :slight_smile:

In that case, are you able to run bzip2 on the windows commandline?

Thanks for the hint! Turns out I had to fix the path variable manually for bzip2. It’s not set on installation, neither of Solana nor of a separate bzip2, so win10 setup the latter seems to be sloppy.
