Problem

cargo check is giving me this output

error: dep-info invalid
note: this is an unexpected cargo internal error
note: we would appreciate a bug report: https://github.com/rust-lang/cargo/issues/
note: cargo 1.45.0-nightly (cb06cb269 2020-05-08)

Since it explicitly wants me to file a bug report, I am dutifully doing so.

Steps

For me, all I did was:

1. Pull servo from https://github.com/servo/servo (master is currently at 14303bd651e248e6e7a73759d622658088f9ddf1)
2. run 'cargo check'

That probably wont reproduce it for you because if it did, none of the Servo devs would be able to work, which probably isn't happening.

Possible Solution(s)

I suppose there might be data in my ~/.cargo from previous versions of cargo that just ain't playing nicely. But it is out of my depth to speculate on a solution.

Notes

Output of cargo version:
cargo 1.45.0-nightly (cb06cb2 2020-05-08)

My system is ArchLinux, amd64
