When go get complains about terminal prompts disabled, set environment variable GIT_TERMINAL_PROMPT to 1 to enable it.


# export GIT_TERMINAL_PROMPT=1
$ GIT_TERMINAL_PROMPT=1 go get xxx

                Rust: xxx syntax is experimental
              
          

        

      

        

  

      

    
When rustc complains that xxx syntax is experimental, switch to nightly build


$ rustup toolchain install nightly
$ rustup default nightly


If some feature has to be activated, the compiler usually say which one.
