error: failed to select a version for `rusttype`

[giappi]

I cloned and built this project, and I get a error.
Terminal Log:

Updating registry https://github.com/rust-lang/crates.io-index
error: failed to select a version for rusttype (required by piston2d-gfx_graphics):
all possible versions conflict with previously selected versions of rusttype
version 0.2.0 in use by rusttype v0.2.0
possible versions to select: 0.2.1

How to fix it ? Thank your for support.
Best Regards.

@giappi This repo's dependences haven't been update, I've run through it with dependences as below:

[dependencies]
rustc-serialize = "0.3"
rand = "0.3.7"
piston_window = "0.64.0"
pistoncore-sdl2_window = "0.41.0"
piston2d-opengl_graphics = "0.42.0"

It should work

I'm getting this error too, latest version.

#25 It works @UNST4BL3

@MrKiven This is still an issue, unless there's a branch I need to switch to

[HopperMCS]

@MrKiven Successfully compiled (idk about run yet) literally just by deleting the Cargo.lock file

[MrKiven]

@MGageMorgan yeah

Can confirm problem. @fanyer's solution + deleting cargo.lock fixed it.

(rust first timer here!) I was having the same problem. So I updated Cargo.toml (as @fanyer) suggested and removed Cargo.lock. I then did cargo build and I am seeing a lot of error messages like this.
