Errno::ENOENT: No such file or directory when trying to execute chromedriver -v

[svenagnew]

Hi,

I'm attempting to execute chromedriver in an alpine-based Docker container (as part of a test suite using Capybara).

System details as follows:

bash-4.3# rbenv version
2.3.1 (set by /root/.ruby-version)
bash-4.3# which chromedriver
/usr/local/rbenv/shims/chromedriver
bash-4.3# bundle show chromedriver-helper
/usr/local/rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/chromedriver-helper-1.1.0
bash-4.3# ls -alh /root/.chromedriver-helper/2.33/linux64/chromedriver
-rwxr-xr-x    1 root     root        8.5M Dec  5 08:12 /root/.chromedriver-helper/2.33/linux64/chromedriver
bash-4.3# uname -a
Linux 65a0a1bfa8f9 4.9.49-moby #1 SMP Wed Sep 27 23:17:17 UTC 2017 x86_64 Linux

When I execute bundle exec chromedriver -v I expect to see version information in the output. Instead I get the following error:

bash-4.3# bundle exec chromedriver -v
bundler: failed to load command: chromedriver (/usr/local/rbenv/versions/2.3.1/bin/chromedriver)
Errno::ENOENT: No such file or directory - /root/.chromedriver-helper/2.33/linux64/chromedriver
  /usr/local/rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/chromedriver-helper-1.1.0/lib/chromedriver/helper.rb:16:in `exec'
  /usr/local/rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/chromedriver-helper-1.1.0/lib/chromedriver/helper.rb:16:in `run'
  /usr/local/rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/chromedriver-helper-1.1.0/bin/chromedriver:5:in `<top (required)>'
  /usr/local/rbenv/versions/2.3.1/bin/chromedriver:23:in `load'
  /usr/local/rbenv/versions/2.3.1/bin/chromedriver:23:in `<top (required)>'

As can be seen from the above output, the system is failing to detect the existence of the .chromedriver-helper directory.

It may be worth noting that the OS as a chromedriver executable installed:

bash-4.3# /usr/bin/chromedriver -v
ChromeDriver 2.27 (94b3700c8cfd6ef738a417983f710f6ab96b8638)

However, I would expect both to be able to co-exist.

We are seeing the same issue without the OS chromedriver installed. When doing ls -al, all appears fine (i.e. executable is present and has x flag):

# ls -al /root/.chromedriver-helper/2.33/linux64/
total 12748
drwxr-xr-x    2 root     root          4096 Dec  5 13:31 .
drwxr-xr-x    3 root     root          4096 Dec  5 13:29 ..
-rwxr-xr-x    1 root     root       8950080 Dec  5 13:31 chromedriver
-rw-r--r--    1 root     root       4091651 Dec  5 13:31 chromedriver_linux64.zip

When trying to run it manually, the following happens:

# /root/.chromedriver-helper/2.33/linux64/chromedriver
sh: /root/.chromedriver-helper/2.33/linux64/chromedriver: not found

@svenagnew: I found the issue to be related to the glibc library that isn't available on Alpine via the main repos. There is https://github.com/sgerrand/alpine-pkg-glibc that you can use to compile with, but for chromedriver, it needs version 2.0, that repo only has 2.22+ available. Ended up removing the chromedriver-helper gem and just using the Alpine supplied version via apk add chromium-chromedriver. Everything is now working (finally).

@cobusbernard - good catch.

I'll remove and install directly as you suggest. Thanks for the heads up.

I'm interested if anyone thinks this implies any missing behavior in chromedriver-helper? I just merged better handling for platform detection, and there's a discussion at #51 around how the gem should handle unsupported platforms ... which is tangentially related to platforms that already have chromedriver installed.

You saved my life.
With apk add chromium-chromedriver I've got a working chromedriver in docker/kubernetes with jenkins, after 3 days of research.

Closing as it's not clear if there's anything the gem should be doing differently. Happy to re-open if people would like to discuss.
