No such file or directory (os error 2)

[TriplEight]

Hello, thanks for the great tool!

I'm trying to make it work in CI. And I can give a lot of feedback in future.

Tried with many images and repositories, manually for starters.

cargo-chef v0.1.6

Error:

root@e893dc1d44bf:/builds/cargo-contract# cargo chef prepare  --recipe-path recipe.json
Error: Failed to compute recipe

Repro:

run an image

docker run -it paritytech/contracts-ci-linux:4e476221-20201029

and there

git clone https://github.com/paritytech/cargo-contract .
cargo install cargo-chef
cargo chef prepare  --recipe-path recipe.json

The similar stuff happened to the paritytech/ink-ci-linux:65ef4994-20201008 image with https://github.com/paritytech/ink repo
and paritytech/ci-linux:2773c6ea-20201028 with https://github.com/paritytech/substrate. Except the latter is on stable toolchain and didn't show the unwind in the error.

Tried both with docker and podman.

I had the same error when not having set a WORKDIR. Setting it solved it for me.

[TriplEight]

Just tried and it didn't help :/

Bit busy these days, I'll try to have a look before next week 👍

[NathanHowell]

@TriplEight can you try this one cargo install --git https://github.com/NathanHowell/cargo-chef --branch with-manifest-fixes? I hit a few issues with my workspace project including this one.

[TriplEight]

@NathanHowell this works, and it is a huge improvement!
Tested with 3 workspace repositories I've mentioned here.

I've faced some other problems, will file them in the other issues.

[LukeMathWalker]

The fix for this is in master - thanks @NathanHowell!
