The trait std::ops::Try is not implemented for impl

i clone https://gitlab.com/pwoolcoc/soup and run example file,every thing is ok,but when i create a project,but when i created a same file as the example file,i encountered some strange error.:
the code is

use std::collections::HashSet;
use std::fmt::Error;
use soup::Soup;
use reqwest;
fn main() -> Result<(), Box> {
let resp = reqwest::get("xxx")?;
let soup = Soup::from_reader(resp)?;
let result = soup
.tag("section")
.attr("id", "main")
.find()
.and_then(|section| {
section
.tag("span")
.attr("class", "in-band")
.find()
.map(|span| span.text())
});
assert_eq!(result, Some("Crate soup".to_string()));
Ok(())
}

cargo file

[package]
name = "testquestion"
version = "0.1.0"
authors = ["wangyiran"]
edition = "2018"
[dependencies]
soup = "0.3"
reqwest = { version = "0.10.0-alpha.2", features = ["blocking"] }

What did I miss? Please give me some suggestions´╝îthanks so much!

Some errors have detailed explanations: E0277, E0599.
For more information about an error, try rustc --explain E0277.
error: could not compile testquestion.

You should use reqwest::blocking::get. reqwest::get is the async version. Adding the blocking feature flag only enabled the blocking module. Changing reqwest::get is not allowed, as feature flags are additive, which means that if one crate uses reqwest without blocking, and one uses reqwest with blocking, the compiled version of reqwest has the blocking feature flag.

As I already wrote on stackoverflow you should follow the hint.
