That's weird. What toolchains and associated toolchains do you have installed? Can you try reinstalling (removing and installing) the entire toolchain and see if the issue persists?

It's working fine after reinstalling toolchains.Thx.

This happens to me as well. Maybe there are some issues with the recent nightly updates (I'm using nightly rust, msvc toolchain).

Reinstalling works for me as well, though.

I had a similar issue when trying to update 1.43.0 -> 1.44.0:

error: failed to install component: 'rust-src', detected conflict: '"lib/rustlib\\manifest-rust-src"'

Reinstalling the toolchain (stable-x86_64-pc-windows-msvc) helped.

Same problem and reinstalling works.

As nobody else has said this, the following commands fixed it

rustup toolchain list
# get the name of the installed toolchain(s) and use that in the next line
rustup toolchain uninstall stable-x86_64-unknown-linux-gnu
rustup toolchain install stable

Old thread, but to help people finding this via Google:
