Getting "Docker executable not found."

[chrisnicola]

I have docker installed on OSX as well as the docker-sync gem. But I am still getting this error. docker and docker-compose commands are available in /usr/local/bin and that is in /etc/paths and available via the terminal.

The exact error is:

Docker executable not found. Install Docker or set ruby-lsc.commandWithArgs setting

Thanks for your reporting!

Could you show me the result of echo $PATH on your terminal?

[mtsmfm]

And could you try ruby-lsc.commandWithArgs setting?

{
    "ruby-lsc.commandWithArgs": [
        "/usr/local/bin/docker", "run", "--rm", "-i", "mtsmfm/language_server-ruby"
    ]
}

Yes that and it does work. The path is:

/usr/local/opt/rbenv/shims /usr/local/sbin ./bin /Users/chrisnicola/bin /usr/local/opt/rbenv/shims /usr/local/opt/rbenv/bin /usr/local/bin /usr/bin /b
in /usr/sbin /sbin /opt/X11/bin /Library/Frameworks/Mono.framework/Versions/Current/Commands /usr/local/opt/rbenv/shims /usr/local/sbin ./bin /Users/c
hrisnicola/bin /usr/local/opt/rbenv/bin /Applications/Postgres.app/Contents/Versions/latest/bin /Users/chrisnicola/.fzf/bin /Applications/Postgres.app
/Contents/Versions/latest/bin

Only thing I can think of is that vscode isn't loading the shell path.

Hmm, could you try restarting (not reloading) vscode and macOS?

I'll investigate how vscode detect PATH 🤔

@mtsmfm VSCode loads env successfully if it's launched from command line, otherwise vscode has no idea about the shell path. To mitigate this problem, we can load the shell path manually when the extension gets activated. Here is how we handle this issue in VSCode Ruby extension https://github.com/rubyide/vscode-ruby/blob/master/src/utils.ts#L25 , we can use the same technique here.

@rebornix Thank you for your information!

I can't reproduce "Docker executable not found" problem by double-click vscode icon.

Could you tell me how can I reproduce?

I noticed that vscode.workspace.rootPath will be undefined when we don't open any project but this is another problem so I'll create another issue

args = ["run", "--rm", "-i", "-v", `${vscode.workspace.rootPath}:${vscode.workspace.rootPath}`, image];
