If you do rustup update --force
(this may mean you don't get all the components you have already installed) you should get a more up-to-date nightly
(say 2020-10-31
).
That one should build racer
just fine.
This problem seems to be due to rust-ap-rustc_data_structures
having been released on a newer rust src than what you have available in your rustup
.
Thanks, @nlopes. I just checked, your temporary solution works fine!
Can confirm that @nlopes' suggestion works for me too! Thanks! =D
Yes ty for @nlopes suggestion! Rust really has a friendly community
@nlopes advise works.
I can confirm that the solution works.
same here
I have tried @nlopes' suggestion but i still get errors when building racer.

I think you just need to build it from the latest master.
I think you just need to build it from the latest master.
I thought the command cargo +nightly install racer
was doing that. I can see the version 2.1.40 in the output which match the latest release on the GitHub page.
