Rails4-错误Errno :: EINVAL：无效的参数@ rb_sysopen-路径/路径/路径

Question

Hello, after running bundle install (or update) today (27-Aug-2015) I received this error:

ERROR Errno::EINVAL: Invalid argument @ rb_sysopen - C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/app/assets/images/cp-points-icon.ico

As you can see, the path "C:/_Daten" is repeated 5 times.
I cannot imagine why and where it happens.
My _form.haml.html looks like this:

<%= image_tag 'cp-logo.png', class: "logo", style: "height:18px; width:auto; " %>

This happens on my Windows 10 development environment.
My Ubunt15.04 development environment is showing the icons and pictures quite correct.
And now checked on my Win7 development environment. That is bringing up the same issue.

Issue is: for all pics and icons and glyphicons the path is being inserted more than one time.
This is my code for showing glyphicons:

<i class="glyphicon glyphicon-home"> Home</i>

And the error is like this:

ERROR Errno::EINVAL: Invalid argument @ rb_sysopen - C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/C:/_Daten/Ruby/ai/C:/Ruby21/lib/ruby/gems/2.1.0/gems/bootstrap-sass-3.3.4.1/assets/fonts/bootstrap/glyphicons-halflings-regular.woff

So my question now is: how can I take control of the path for the glyphicon-file.
Any help from anyone?
Thanks.

Answer 1

On 02-Sep-2015 the sprockets gem has been updated to version 3.3.4 .
I checked my app with this version and all seems to be displayed correctly.
There are no more issues with displaying images, icons and glyphicons.
The path is now not added more than needed.

Solution: Do not use sprockets gem in version 3.3.3 as it is buggy. Update the sprockets gem to 3.3.4.

This should be the process to install new gems:
a) install manually, do not use bundle install, as that is updating all existing gems
b) after checking the newly installed gem, include that into your gemfile with a specific version to ensure no updates will be done in an unattended way.

Hope this helps.
