Caching an exe stored at /usr/bin

Actions Cache

Discussion Details

In a workflow, I need to use the Exo CLI, which is installed at/usr/bin/.

Is there a way to cache it so I don't have to reinstall it every time I run the workflow?

I tried

    - name: Cache Exo CLI
      id: cache-exo-cli
      uses: actions/cache@v4
      with:
        path: /usr/bin/exo
        key: ${{ runner.os }}-exo-cli

But the runner doesn't have access to that path.

Thanks

I don't thing caching system0wide paths like /usr/bin/... - in your case - will work as expected with Github runners because the actions/cache works by storing files within the workspace or directories that your job has read/write access to. Secondly, system directories (like /usr/) are essentially read-only, so they cannot be cached or used in the cache action.

A good approach (i think) would be to install Exo into a directory like $home/.exo or a workspace sub directory and cache that

with
path: ~/.exo
key: .....

With this you could: avoid permission issues, cli is cached between workflows and you control where it resides and when it updates.

Thanks for the reply. The "problem" is that the installation script installs the binary at /usr/bin and I haven't found a way to change that path.

if I'm not mistaken, you cannot cache /usr/bin on GitHub-hosted runners, move your binary to a writable path like $HOME/.local/bin and cache that instead
