rustup update error

[Eh2406]

I get this error today:

C:\rust_things>rustup -V
rustup 1.8.0 (cb2d14862 2017-12-17)
C:\rust_things>rustup self update
info: checking for self-updates
error: could not create link from 'C:\Users\finkelman\.cargo\bin\rustup.exe' to 'C:\Users\finkelman\.cargo\bin\rustc.exe'

Don't know what it means just reporting.

Win 10, 64 bit.

[Antelope13]

I'm getting the same thing. Win 10, 64 bit.

[kjeremy]

Seeing this on Windows 7 x64 for cargo, cargo-fmt, rls, rustc, rustdoc, rustfmt, rust-gdb, and rust-lldb

[Eh2406]

I don't know if it is relevant but cargo is not finding cargo-fmt despite it being on my path.

I ran into the same problem. In "raw.rs" the function hardlink tries to unlink the destinaton file but does not care about the io::Result. This call fails on my system. Any attempt to link the file fails due to an already existing file.

As far as I understand informations from MSDN right now hardlinks are not removeable when the the file is locked. It seems to be locked due to running rustup.exe.

Has the mechanisms for handling .cargo/bin changed recently? The Problem was introduced with #1310 and cb2d148622a2584839a0cb1e8f8926e5662f59b6.

Possibly related. Running rustup self update on Windows 10 64-bit in the git-for-windows bash shell. Past updates have worked successfully. No rustup executables exist in cargo/bin after the error messages below.

Downloading rustup-init.exe and running from a regular command prompt I get the following errors:

C:\Users\mike\Downloads>rustup-init.exe --no-modify-path

Running cargo uninstall rustfmt-nightly and allows rustup to install successfully but subsequent self updates fail:

[CryZe]

Yeah, I can confirm that rustup update does not work anymore. You need to delete all of the tools it mentions at the same time for it not to error out. It'll error out on the next update again though

[CryZe]

These are the tools you need to delete:

[petertiedemann]

Me too (also win 10 x64)

We're seeing the same failure across many AppVeyor builds, eg.

Any solves or workarounds would be very welcome -- this is a blocking issue for many of our projects.

[DustinByfuglien]

Confirm.
I have this problem in Windows 7 x64.

[nonsensecreativity]

Confirm,
I have this problem in Windows 10 x64

[workingJ]

I do have the same issue too.
Win 10 x64

I think there are some changes about how Windows handle the path and link, you may reference URLs below:

[mirandadam]

I am also getting this. Windows 10, 64 bit.
Also happens when:

• fully uninstalling rust and installing plain vanilla stable
• fully uninstalling rust and installing nightly without installing anything else
  Is there a fix in sight?

[SProst]

I began receiving this error after adding the rls-preview component. Not sure if that is related however.

[kankri]

I'm getting a similar error:

>rustup self update
info: checking for self-updates
info: downloading self-update
info: rustup updated successfully to 1.8.0

>error: could not remove 'rustup-bin' file: 'C:\Users\user\.cargo\bin\rustup.exe'
info: caused by: Access is denied. (os error 5)

I noticed that the last error messages appear after a new prompt, after rustup.exe has exited. This seems to indicate that the failing operation is done in a subprocess. Looking at Procmon output this is indeed the case:

rustup.exe self update
    "C:\Users\user\.cargo\bin/rustup-init.exe" --version
    "C:\Users\user\.cargo\bin/rustup-init.exe" --self-replace

That last last command is done after "rustup.exe" exits in self_update.rs:

#[cfg(windows)]
pub fn self_replace() -> Result<()> {
    try!(wait_for_parent());
    try!(install_bins());

    Ok(())
}

This code hasn't been changed for a long time, so I don't know why it started failing now for me, but I think there is a race condition: The executable file is not immediately accessible after the process has exited. (This presentation and the similarly named Youtube video give interesting facts about e.g. the asynchronous nature of file deletion in Windows: Racing the Filesystem by Niall Douglas.)

I would try to have a sleep/retry loop around install_bins() in that function.

[alexcrichton]

@Yanpas an updated version of rustup had not been released, it shoudl be fixed now.

[hherman1]

Having this issue. Was on a pretty old version of rustup and updated recently. GOt the warnings about rustfmt and cargo-fmt, complied, and suffered.

The error:

PS C:\Users\me> rustfmt
error: toolchain 'stable-x86_64-pc-windows-msvc' does not have the binary `rustfmt.exe`

Attempt to solve:

PS C:\Users\me> rustup component add rustfmt
error: toolchain 'stable-x86_64-pc-windows-msvc' does not contain component 'rustfmt' for target 'x86_64-pc-windows-msvc'

Version:

PS C:\Users\me> rustup --version
rustup 1.11.0 (e751ff9f8 2018-02-13)

[Arnavion]

@hherman1 Perhaps you commented on the wrong issue. Anyway you're trying to add a component named rustfmt that does not exist, thus the error. The component you're looking for is named rustfmt-preview and you can see from rustup component list

I just got the same error updating to 1.30.
