On Windows, projects living at the root of a drive don't work

[wagenet]

I had a project that was directly mounted to E:. When I tried to run cargo I got the following unclear error: "error: invalid path url E:". I was able to resolve this problem by moving my project into a directory.

Hm I seem to be unable to reproduce this locally in a C: drive, do you have a set of instructions of how to reproduce? I'd be surprised if it was specific to E: as opposed to C:...

[wagenet]

@alexcrichton I had a shared directory mounted to E: with a cargo project in that directory. Any cargo command that tried to do something with my code (i.e. not cargo -V, but cargo test) caused this error. Our project is also set up as a workspace with members inside of it.

[alexcrichton]

Oh this may be related to the shared drive then maybe? We've had reports of fs::canonicalize returning errors in these situations in the past.

Could you gist the full error you saw as well as a description of the structure of the project (e.g. workspace layout)

[wagenet]

There was no error message except what I posted. The project was a clone of https://github.com/tildeio/helix.

This is the similar-sounding issue that has to do with fs::canonicalize: #2990

Given that this issue is stale, I'm going to close this.

@wagenet if this is still an issue, could you try running RUST_LOG=debug cargo build in the project on shared drive and reopen with a gist of the output? Thanks!

@carols10cents I'm still seeing issues with rust 1.22.0-nightly (d6d711dd8 2017-10-10). I'm not seeing any additional output beyond the single line error message. I'm investigating more right now.

[wagenet]

Whoops, I forgot to add the RUST_LOG=debug. Here's the output I get:

$ RUST_LOG=debug cargo build
DEBUG:cargo::build: executing; cmd=cargo-build; args=["C:\\Users\\Peter\\.rustup\\toolchains\\nightly-x86_64-pc-windows-msvc\\bin\\cargo.exe", "build"]

Interesting, thank you! Reopening!

I'm a bot so this may be in error! If this issue should remain open, could someone (the author, a team member, or any interested party) please comment to that effect?

The team would be especially grateful if such a comment included details such as:

• Is this still relevant?
• If so, what is blocking it?
• Is it known what could be done to help move this forward?

Thank you for contributing!

(The cargo team is currently evaluating the use of Stale bot, and using #6035 as the tracking issue to gather feedback.)

If you're reading this comment from the distant future, fear not if this was closed automatically. If you believe it's still an issue please leave a comment and a team member can reopen this issue. Opening a new issue is also acceptable!
