rustrustup

No default toolchain configured after installing rustup


I installed Rust using rustup, but when I try to enter a Rust command like cargo or rustc in my console, the following error appears:

error: no default toolchain configured

Is this a known issue?


Solution

  • If it seems that rustup did not successfully install and configure the stable toolchain, you can do it manually:

    rustup install stable
    rustup default stable
    

    After testing, it seems like my incomplete installation may have been caused by a network error. You can also try to reinstall to solve the problem.
