I get a file not found error from rubocop (using linter-rubocop)

[jaresty]

When editing a file, I see no linting, but if I open the javascript console I can see an error message that says "env: ruby_executable_hooks: No such file or directory".

• I have rubocop installed using rvm
• The command that appears to be run looks like /Users/jaresty/.rvm/gems/ruby-2.1.2/bin/rubocop --format emacs /var/folders/2_/7s_9bc4s5q586np5tmjh3tn80000gr/T/114421-34324-5q1bi0source.ruby

[iam4x]

Hi @jaresty I'll look into it,
Can you provide a gist of an example file to lint?

And the output of:

• $ rubocop --version
• $ ruby --version

I have ruby 2.0.0p451 installed with rvm and gem rubocop v0.22.0 and no issues.

[jaresty]

It happens with any ruby file at all. I'm not sure if it's a
linter-rubocop issue or a linter issue.

Thanks,
Josh

@jaresty I edited my message, as you answered by mail you didn't noticed it.

It seems more an issue with your installation of rubocop can you give me your ruby --version and rubocop --version.

Also can you try to lint a file with the command line directly in shell with: $ rubocop path/to/file.rb and give me the result.

First try to update rubocop version 0.22.0 is out now.

I'm looking into it.

[jaresty]

Did you install ruby with rvm? I will update rubocop as soon as I get back
home (I'm out for the day now)

Yes, installed with rvm too ;)

btw co-workers are telling me that https://github.com/sstephenson/rbenv is better now than RVM (fyi)

Can I have an example file with his extension which fails? Into a gist.

[iam4x]

It's looking for /var/folders/2_/7s_9bc4s5q586np5tmjh3tn80000gr/T/114421-34216-1eagftfsource.ruby which doesn't seems to exists. And the extension of the file is kinda weird.

[jaresty]

Right: I don't know where that file name is coming from; I assumed it was
something internal to atom or the linter plugin.

@jaresty Yep, it's intern to Linter plugin. To lint on modify, we copy the text buffer into a temporary file which will be used by the specific linter.

Normally it should add the correct extension to the file, so something is going wrong. When you have time, give me a not working example file ;)

[jaresty]

Could you send me an example file that works for you too?

This file is named player.rb, and produces the error when loaded into the linter. It happens actually with any .rb file I try to use.

Hi @jaresty I add so much work this week, gonna look more into it today. But I have problem to reproduce :/

With your file, on OSX 10.9.3, ruby 2.0.0p451, rubocop 0.22.0 I have no errors:

[jaresty]

Would it help if I could show you? I can screen share with google plus I
think.

@jaresty Okey It seems to doesn't find the temporary file created from the buffer, on what OSX version are you working? They may be an issue while creating the temp file.

[jaresty]

I'm on Mavericks (10.9), but this happened on my work machine running 10.8
too.

Are other linters working? Like the jshint or coffeelint ?

jshint doesn't seem to throw errors, but I don't see any visible linting
feedback so I'm not sure if it's really working.

@jaresty Looks like you are the only one who can debug this! Can you check if the https://www.npmjs.org/package/temp package works on your system? Sounds like it doesn't create the file from the editor buffer.

I can help you with this if you don't have any experience into node and javascript.

[jaresty]

What command should I run to test the package?

@jaresty You should try to create a little nodejs script using the module. Creating a temporary file and see if it's working on your system. I'm not sure how to help you.

If someone has an idea? @park9140 @hd-deman

[jaresty]

Is there some sample code I could look to to get a specific example? Where
in the package is the tempfile code used? It would help if I could make my
example as close to the package's usage as possible.

Thanks,

Josh

I used the example I found on the module website, copied and pasted into
the console in atom, and didn't get any errors:

// Fake data
var myData = "foo\nbar\nfoo\nbaz";

// Process the data (note: error handling omitted)
temp.open('myprefix', function(err, info) {
if (!err) {
fs.write(info.fd, myData);
fs.close(info.fd, function(err) {
exec("grep foo '" + info.path + "' | wc -l", function(err, stdout) {
console.log(stdout.trim());
});
});
}
});

Write this in something.js

var temp = require('temp');
temp.track();

// Fake data
var myData = "foo\nbar\nfoo\nbaz";

// Process the data (note: error handling omitted)
temp.open('myprefix', function(err, info) {
  if (!err) {
    fs.write(info.fd, myData);
    fs.close(info.fd, function(err) {
      exec("grep foo '" + info.path + "' | wc -l", function(err, stdout) {
        console.log(stdout.trim());
      });
    });
  }
});

And then run in your shell: $ node something.js

You need to install the module temp by running: $ npm install -g temp

[jaresty]

When I run this code, the result is "2". It works on my system.

I think I've figured out the issue:

On a mac when you install rubocop using rvm and try to set up the linter-rubocop package to point to the rvm (not the mac-system) rubocop, that file contains the line #! env ruby_executable_hooks, which gives a file-not-found error on the mac since your windowed session does not know how to access rvm.

[iam4x]

Mind blown

Waaaahou!

[park9140]

@jaresty, try installing atom command line aliases and then start atom from the command line. This issue exists in a bunch of the linters in sublime as well and that fixes the issue there.

The underlying problem being that certain package managers like nodenv, rbenv, rvm... only install their path in the bash profile, and in osx this file does not get added to the standard application context.

I would suggest that we do an interactive process for discovering a linter location. Each linter could provide guesses for the linter install location, and failing that the base linter could alert the user to input the base linter location so that they are told when the above issue results in not finding the linter executable requirement.

[johanneswuerbach]

Can't the bash_profile not be loaded into the atom / linter environment? This would solve this issue more automatically and terminal commands would also work in linters.

[park9140]

It could, however there are still those among us who do not use bash profile as well. I use fish, and a couple other people around my office use zsh, neither of which use the bash_profile for sourcing path information by default. So even if we pulled the bash profile we would not guarantee access to the correct path data. Though I would love to see atom automatically include the bash profile path info.

[jaresty]

@park9140 that did it. Good idea-thanks!

[dmnd]

The specific issue here seems to be resolved. Closing, but see #150 for @johanneswuerbach's suggesting of loading the profile into Atom.
