I’m installing sqlx on Ubuntu 18.04:
cargo install --git https://github.com/launchbadge/sqlx sqlx-cli
I get the error
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 rustc 1.47.0 (18bf6b4f0 2020-10-07) $ cargo --version cargo 1.47.0 (f3c7e066a 2020-08-28)
How can I solve the error and complete the installation?
