rust - 由于类型不匹配，sqlx 安装失败

Question

我在 Ubuntu 18.04 上安装sqlx ：

cargo install --git https://github.com/launchbadge/sqlx sqlx-cli

我得到错误

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

$ rustc --explain E0308                                                                                   
    
    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.

$ rustc --version
