cargo binary doesn't work with nightly-2022-07-10 specified in rust-toolchain.toml

[aminya]

Problem

I used to specify the toolchain version that I want to use in rust-toolchain.toml, but recently I get an error like this when I try to use cargo

cargo
error: the 'cargo.exe' binary, normally provided by the 'cargo' component, is not applicable to the 'nightly-2022-07-10-x86_64-pc-windows-msvc' toolchain  

Steps

Create a rust-toolchain.toml file.

[toolchain]
channel = "nightly-2022-07-10"
components = [
  "cargo",
]

Install a nightly toolchain using rustup. Then try to run cargo in this workspace.

Possible Solution(s)

• Removing rust-toolchain.toml
• Changing nightly-2022-07-10 to nightly

Strangely enough, by uninstalling the nightly-2022-07-10-x86_64-pc-windows-msvc toolchain using rustup uninstall and trying again, now cargo works! There is definitely a bug somewhere in rustup.

I'm not familiar with the publishing process for the channels, but my hunch here is that cargo wasn't published or some such - though thats not entirely consistent with the output you've pasted.

This has affected me as well (Ubuntu 22.04). Nightly doesn't build, but specific versions do, e.g. nightly-2022-07-15. Timeline matches up, too. I first experienced this a week ago and had to circumvent it.

This worked for me. I suspect somewhere, someone pushed a bad version of nightly on the linux-gnu architecture, and the only solution was to do a complete uninstall and reinstall.

I was having a different toolchain, but tried the same thing, of uninstalling and then reinstalling worked for me

In my case, I had to run rustup self uninstall and full reinstall to have cargo working again.

I uninstalled the nightly toolchain, and reinstalled and it started to work, so can confirm OP is right.
