I've created act-failing-python-cache with additional details.

This was tested with act master branch as of 11/10/2020:

$ git log -1
commit 695c4966843d319933d110316032863d138a721b (HEAD -> master, upstream/master, origin/master, origin/HEAD)
Author: Steffen Seckler <38119442+SteffenSeckler@users.noreply.github.com>
Date:   Tue Nov 10 23:55:27 2020 +0100

    Adds ability to use container images from matrices. (#413)
    
    Uses rc.ExprEval.Interpolate on container image.

I was trying to use actions/setup-python@v2 and actions/cache@v2:

And Python cache step fails becasue path is empty and "not supplied":

[t1/Linux build and test]   ❌  Failure - Python cache
Error: exit with `FAILURE`: 1

As it so happens while creating the test case I found a hack to that solves the problem.
If you add a step between Set up Python and Python cache that displays env.pythonLocation
(i.e. uncomment lines 22-24 of t1.yml above):

      - name: Display env.pythonLocation
        run: |
          echo env.pythonLocation=${{ env.pythonLocation }}

[t1/Linux build and test] ❌ Failure - Python cache Error: exit with `FAILURE`: 1 ``` As it so happens while creating the test case I found a hack to that solves the problem. If you add a step between `Set up Python` and `Python cache` that displays `env.pythonLocation` (i.e. uncomment lines 22-24 of t1.yml above): ``` - name: Display env.pythonLocation run: | echo env.pythonLocation=${{ env.pythonLocation }} ``` Then `act` can complete all steps: ``` 1 $ ~/prgs/nektos/forks/act/dist/local/act 2 [t1/Linux build and test] 🧪 Matrix: map[python-version:3.6] 3 [t1/Linux build and test] 🚀 Start image=winksaville/ubuntu-dev:20.04 4 [t1/Linux build and test] 🐳 docker run image=winksaville/ubuntu-dev:20.04 entrypoint=["/usr/bin/tail" "-f" "/dev/null"] cmd=[] 5 [t1/Linux build and test] 🐳 docker cp src=/home/wink/prgs/python/projects/hw/. dst=/github/workspace 6 [t1/Linux build and test] ⭐ Run actions/checkout@v2 7 [t1/Linux build and test] ✅ Success - actions/checkout@v2 8 [t1/Linux build and test] ⭐ Run Set up Python ${{ matrix.python-version }} 9 [t1/Linux build and test] ☁ git clone 'https://github.com/actions/setup-python' # ref=v2 10 [t1/Linux build and test] 🐳 docker cp src=/home/wink/.cache/act/actions-setup-python@v2 dst=/actions/ 11 [t1/Linux build and test] 💬 ::debug::Semantic version spec of 3.6 is 3.6 12 [t1/Linux build and test] 💬 ::debug::isExplicit: 13 [t1/Linux build and test] 💬 ::debug::explicit?

My diagnosis of the problem is that when a new step is created and newStepExecutor is invoked, see below. It setups a new environ with _ = sc.setupEnv()(ctx) which "inherits" the environment from the previous step and then creates an expression evaluator for the new step with rc.ExprEval = sc.NewExpressionEvaluator():

func (rc *RunContext) newStepExecutor(step *model.Step) common.Executor {
	sc := &StepContext{
		RunContext: rc,
		Step:       step,
	}
	return func(ctx context.Context) error {
		rc.CurrentStep = sc.Step.ID
		rc.StepResults[rc.CurrentStep] = &stepResult{
			Success: true,
			Outputs: make(map[string]string),
		}

		_ = sc.setupEnv()(ctx)
		rc.ExprEval = sc.NewExpressionEvaluator()

		if !rc.EvalBool(sc.Step.If) {
			log.Debugf("Skipping step '%s' due to '%s'", sc.Step.String(), sc.Step.If)
			return nil
		}

		common.Logger(ctx).Infof("\u2B50  Run %s", sc.Step)
		err := sc.Executor()(ctx)
		if err == nil {
			common.Logger(ctx).Infof("  \u2705  Success - %s", sc.Step)
		} else {
			common.Logger(ctx).Errorf("  \u274C  Failure - %s", sc.Step)
			rc.StepResults[rc.CurrentStep].Success = false
		}
		return err
	}
}

This is fine but there is a problem, in setupEnv it loops through all of the environment variables interpolating any ${{ xxxx }} into "concrete" values:

		for k, v := range env {
			env[k] = rc.ExprEval.Interpolate(v)
		}

But notice that setupEnv uses rc.ExprEval which is the evaluator for the previous step that was created before the previous step was executed. Therefore the rc.ExprEval being used does not contain any env values from the previous step itself, but only values from "its previous step". Therefore, if the "new step" references environment variables that were created or updated in the just completed step they will be empty or old values.

Here is the full code for func setupEnv:

func (sc *StepContext) setupEnv() common.Executor {
	rc := sc.RunContext
	job := rc.Run.Job()
	step := sc.Step
	return func(ctx context.Context) error {
		var env map[string]string
		c := job.Container()
		if c != nil {
			env = mergeMaps(rc.GetEnv(), c.Env, step.GetEnv())
		} else {
			env = mergeMaps(rc.GetEnv(), step.GetEnv())
		}

		if (rc.ExtraPath != nil) && (len(rc.ExtraPath) > 0) {
			s := append(rc.ExtraPath, os.Getenv("PATH"))
			env["PATH"] = strings.Join(s, string(os.PathListSeparator))
		}

		for k, v := range env {
			env[k] = rc.ExprEval.Interpolate(v)
		}
		sc.Env = rc.withGithubEnv(env)
		log.Debugf("setupEnv => %v", sc.Env)
		return nil
	}
}

My solution is to call setupEnv and NewExpressionEvaluator a second time. The first invocation will update the enviornemt variables and then rc.ExprEval set and its enviornemt will now be "complete", the second invocation will then have the complete set of environment variables and in my case env.pythonLocation will have the correct value after the second invocations. The diff is at this comment to #419.

I suspect there is a "better" solution, I'll see if I can work something up,
