Problems with bigdecimal gem installation on Windows

questions
1

Hello. I’m having trouble starting Hanami server. Specifically with bigdecimal gem. When I try to start Hanami server, the following problems occur:

hanami server

  Please add the following to your Gemfile to avoid polling for changes:

Run `bundle install` to install missing gems.

When I follow these instructions, all gems except bigdecimal behave appropriately. The following happens with bigdecimal:

An error occurred while installing bigdecimal (3.1.7), and Bundler cannot

An error occurred while installing bigdecimal (3.1.7), and Bundler cannot
continue.

In Gemfile:
  hanami-validations was resolved to 2.1.0, which depends on
    dry-validation was resolved to 1.10.0, which depends on
      dry-schema was resolved to 1.13.3, which depends on
        dry-types was resolved to 1.7.2, which depends on
          bigdecimal

Can you tell me what the problem is? (I’m a beginner, I use Windows).

Hi @Kolockifa, thanks for trying Hanami!

Unfortunately I’m not a Windows user, so I can’t personally replicate your issues, but from the looks of those error messages, this might be more an issue with your general Ruby installation rather than Hanami specifically.

The errors look to be related to permissions: both the gem pristine and bundle install commands are failing with “Permission denied” errors for files kept in C:/Users/1/.local/share/gem/ruby. Can you double check the permissions of the .local/share/gem/ directory? Perhaps you can bulk re-assign ownership of that directory (and all its children) to the user that is running those gem and bundle commands? I expect that should fix it for you.

I double-checked all the rights, everything seems to be in place. I also tried reinstalling ruby. Do you think the situation could get better if I switch to Linux?

@Kolockifa I haven’t personally tried Ruby on Windows, but from my own vantage point, I think you’d more likely find success using Linux, simply because there are more Ruby users and tools focused on that platform. Windows has the Windows Subsystem for Linux, which would let you use a proper Linux environment from within Windows, so perhaps that would be worth a try?
