Sqlx: rust sqlx installation fails due to mismatched types

[iapicca]

Hi all, installing rust sqlx on Ubuntu 18.04

I get the error below

 error[E0308]: mismatched types
     --> sqlx-cli/src/opt.rs:8:20
      |
    8 |     #[clap(short = "D", long)]
      |                    ^^^ expected `char`, found `&str`

    error: aborting due to previous error

    For more information about this error, try `rustc --explain E0308`.
    error: could not compile `sqlx-cli`.

    To learn more, run the command again with --verbose.
    warning: build failed, waiting for other jobs to finish...

    Caused by:

    Expected type did not match the received type.

    Erroneous code example:

    ``
    let x: i32 = "I am not a number!";
    //     ~~~   ~~~~~~~~~~~~~~~~~~~~
    //      |             |
    //      |    initializing expression;
    //      |    compiler infers type `&str`
    //      |
    //    type `i32` assigned to variable `x`
    ``

    This error occurs when the compiler is unable to infer the concrete type of a
    variable. It can occur in several cases, the most common being a mismatch
    between two types: the type the author explicitly assigned, and the type the
    compiler inferred.

I'm new to rust so let me know if I need to provide more details

any idea how to solve the error and complete the installation?

Thank you
