nlopes commented 3 years ago

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.

SFzxc commented 3 years ago

Thanks, @nlopes. I just checked, your temporary solution works fine!

x10an14 commented 3 years ago

Can confirm that @nlopes' suggestion works for me too! Thanks! =D

yiyoascen commented 3 years ago

Yes ty for @nlopes suggestion! Rust really has a friendly community

voland62 commented 3 years ago

@nlopes advise works.

I think you just need to build it from the latest master.

Polensky commented 3 years ago

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.
