#1

My first project with Rust is a webpage scraper so I wanted to install reqwest.
Added the line
reqwest = "0.2"
to dependencies in Cargo.toml,
Version of cargo:
cargo 0.13.0-nightly (eca9e15 2016-11-01)

Version of rustc:
rustc 1.13.0 (2c6933acc 2016-11-07)

When I start with commnd

cargo run

I get bunch of errors:

Any ideas what I'm doing wrong?

#2

Your version of Rust is very very old, and reqwest requires a newer version. The newest version of Rust is 1.41.0

#3

Because you're using the ancient version of the Rust compiler. Rust is a rapidly improving language, new syntax and library improvements are added every 6 weeks. And of course compilers made before those syntax have no clue about it, thus it throws syntax error. How did you installed the Rust toolchains?

#4

Ah, yes. Now I see the date by the rustc ... updating.
Thanks.

#5

And also the version of reqwest is pretty old. The current latest ome is v0.10.1 with fancy async-await support. Why don't you try it?
