I'm getting this on one macOS system:
$ rustup component add rustfmt --toolchain nightly error: component 'rustfmt' for target 'x86_64-apple-darwin' is unavailable for download for channel nightly Sometimes not all components are available in any given nightly.
.. but on my other macOS systems running nightly rustfmt is installed. Though
rustup update keeps saying that rustfmt-preview isn't available. I assume what is happening is that on the other systems it's just keeping the latest available "nightly" rustfmt, but on this system it was either never installed or it disappeared.
But given that the nightly rustfmt that is installed on the other systems has been working mostly very well for a while, I would like to install it on this system as well.
I'm wondering a few things related to this:
- How would I go about finding out which the latest nightly rustfmt is? Is there some site that tracks which components have been packaged for nightly releases?
- How would I go about finding out which specific version of nightly rustfmt I'm using on the other systems?
- How would I go about installing an "old" very specific component version to my "nightly" toolchain (so I get the behavior of my other macOS systems (because I assume it'll pick up rustfmt component updates automatically once they begin being published again)).
