Nightly (1.33.0-nightly) fails on OS X 10.14.1

[d4ncer]

I've been trying to install the nightly to set up Racer, and I keep getting an error when trying to install rust-std:

rustup update nightly
info: syncing channel updates for 'nightly-x86_64-apple-darwin'
info: latest update on 2018-12-25, rust version 1.33.0-nightly (f960f377f 2018-12-24)

error: failed to install component: 'rust-std-x86_64-apple-darwin', detected conflict: '"lib/rustlib/x86_64-apple-darwin/lib/libLLVM.dylib"'

Things I've tried:

• I assumed that it was due to some old install that was not blown away correctly so I tried searching for this conflicting file to no avail.
• I've blown away ~/.rustup & ~/.cargo numerous times, and re-installed.

Not sure if I've even diagnosed the issue correctly, and I can't seem to run the install / update commands with any increased level of verbosity to drill deeper.

Any help would be most appreciated.

+1, exactly the same use case

I can reproduce this on Arch Linux x64.

(By the way, Merry Christmas to anyone reading this thread!)

I'm having this problem as well on Ubuntu 18.04.

As a workaround, rustup toolchain add nightly-2018-12-23 works just fine.

[d4ncer]

Good to know, thanks @flaviut!

As a workaround, rustup toolchain add nightly-2018-12-23 works just fine.

I still have the same issue with installing.

1. I did rustup toolchain add nightly-2018-12-23
2. After i run rustup toolchain install nightly-x86_64-unknown-linux-gnu

rustup target add x86_64-unknown-linux-musl
rustup toolchain install nightly-x86_64-unknown-linux-gnu

`

surely rustup toolchain install nightly-x86_64-unknown-linux-gnu is just installing the latest nightly again, whereas to avoid the bug you should be installing 2018-12-23

[lambda-fairy]

rust-lang/rust#57111 has been fixed and released in the latest nightly. Can we close this?

[d4ncer]

Yup, happy to close 👍 Thanks all!
