Getting "cargo is not installed by default for some virtual environments", while using the correct toolchain action

[vmalloc]

My workflow is something like this:

      - name: Install stable toolchain
        uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
          override: true

      - name: Cargo clippy
        uses: actions-rs/cargo@v1
        with:
          command: clippy
          args: --all --tests -- -D warnings

This workflow works great on GH actions, but run with act, I get errors. Mainly:

[Build/Build]   ❓  ::add-matcher::/actions/actions-rs-cargo@v1/dist/.matchers/rust.json
[Build/Build]   ❗  ::error::cargo is not installed by default for some virtual environments, see https://help.github.com/en/articles/software-in-virtual-environments-for-github-actions

Same. I get | /github/workflow/1: line 2: cargo: command not found with just the basic Rust workflow (without using the actions-rs action).

This is the file:

name: Rust
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Build
      run: cargo build --verbose

EDIT: I saw that this is a "pinned issue". (Didn't know this existed) Which explains what I see.

Solution: Provide the correct runner image. Either provide -P ... on the command line, or provide it in the .actrc file:

.actrc:

-P ubuntu-latest=act-environments-ubuntu:18.04

Tested with:

• the plain cargo build command I posted above.
• the action-rs action.

For just cargo build the rust:latest image works. But the action-rs also needs node support. I decided to trade simplicity (using nektos' image) for disk space.

@siedentop should that be:

-P ubuntu-latest=nektos/act-environments-ubuntu:18.04

I have the same problem. Using -P ubuntu-latest=nektos/act-environments-ubuntu:18.04 didn't help in my case. And it shouldn't be needed, as I use actions-rs/toolchain@v1 to install rustup and cargo manually, just like @vmalloc does.

What confuses me is that rustup show active-toolchain, rustup which cargo, which cargo and cargo -v all work correctly, so I wonder why actions-rs/clippy-check@v1 doesn't find cargo. Internally, actions-rs/clippy-check@v1 uses which cargo to check for the presence of cargo (see https://github.com/actions-rs/core/blob/1b3bf36903648e0f2db0286ede1348abbac16f60/src/commands/cargo.ts#L31), so it's strange that it doesn't work.

Issue is stale and will be closed in 7 days unless there is new activity

This issue persists to this day, making act unusable for many rust projects, and thus shouldn't be closed, I think.

If I put this in my .actrc:

-P ubuntu-latest=nektos/act-environments-ubuntu:18.04

Then run act:

❯ act
[CI/Check-1] 🧪  Matrix: map[rust:stable]
[CI/Check-2] 🧪  Matrix: map[rust:1.31.0]
[CI/Check-1] 🚀  Start image=nektos/act-environments-ubuntu:18.04
[CI/Check-2] 🚀  Start image=nektos/act-environments-ubuntu:18.04

My computer fans spin up like crazy. Worse than compiling a large crate. And it doesn't progress any further than Start image=...

It does for me, I waited around 10 minutes

This works for me:
act -P ubuntu-latest=ghcr.io/catthehacker/ubuntu:rust-latest
Wait until it silently downloads the docker image.

This works for me: act -P ubuntu-latest=ghcr.io/catthehacker/ubuntu:rust-latest Wait until it silently downloads the docker image.

Thank you for this. This worked for me.
