Toolchain with name 'beta-1-aarch64-apple-darwin' does not exist

When I try to install the beta-1 toolchain, I get an error that says that the toolchain doesn’t exist. How do I fix this?


Fuelup has 4 versions: latest, nightly, beta-1, and beta-2. These are available by default. If you are experimenting, the recommended version is latest. If you want to deploy on a specific testnet, use the appropriate toolchain for that testnet.


  1. Make sure you are on the latest fuelup version with the following command: fuelup self update

  2. Run the following command to install the toolchain: fuelup toolchain install beta-1
