Heroku-如何解决“无法加载此类文件-工头/ cli（LoadError）”的问题？ -[Java，Windows，Ruby-on-rails]

Question

I'm following the official Heroku Java tutorial:

Getting Started with Java on Heroku

I've succesfully followed every step up to

Run the app locally

Running the command described in this step:

foreman start web

that on Windows needs to use a specific Procfile:

foreman start web -f Procfile.windows

I get the following error:

C:\Users\Andrea>foreman start web -f Procfile.windows
C:/Program Files (x86)/Heroku/ruby-1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.r
b:36:in `require': cannot load such file -- foreman/cli (LoadError)
        from C:/Program Files (x86)/Heroku/ruby-1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/cus
tom_require.rb:36:in `require'
        from C:/Program Files (x86)/Heroku/bin/foreman:8:in `<main>'

What causes the problem, and how can I fix it ?

Thanks @AndreaLigios for posting my solution on StackOverflow.

@Gespejo is getting below problem taken from GitHub:

I installed heroku in the c:\\Heroku directory but it's still not working. Can you help me? Thanks

 C:>foreman C:/Heroku/ruby-1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- foreman/cli(LoadError) from C:/Heroku/ruby-1.9.3/lib/ruby/ site_ruby/1.9.1/rubygems/custom_requi re.rb:36:inrequire' from C:/Heroku/bin/foreman:8:in 

Follow the below Steps:

• Uninstall Heroku Toolbelt completely from your computer.
• Uninstall Foreman gem by using command gem uninstall 'foreman' .
• Now install Heroku Toolbelt again
• Check foreman is working now or not by running command foreman that will list all commands option supported by foreman

Let us know if problem has solved after executing above listed steps.

Answer 2

The error is caused by the fact that:

Foreman does not work if your installation of Heroku has any special characters or spaces in any directory name or in directory Hierarchy

(thanks to @theajaygupta for finding the solution )

Since the Heroku Toolbelt for Windows installation is defaulting the Heroku path to

C:\\Program Files (x86)\\Heroku

, everyone following the tutorial on Windows will get this error.

The solution is simple: reinstall the Heroku Toolbelt for Windows specifying a path without spaces and special characters. For example:

Valid

• C:\\Heroku
• C:\\SeemsLegitIn2015\\Heroku

Not Valid

• C:\\Program Files (x86)\\Heroku
• C:\\Progra~2\\Heroku
