Saasc 2.4.0 installation error - #include <vector>

[ricvillagrana]

Hi, when I try to do bundle install this dependency is unable to be installed. How can I solve this issue?

OS: macOS Big Sur v11.5.2 Ruby version: ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-darwin20] Rails version: 5.2.6

An error occurred while installing sassc (2.4.0), and Bundler cannot continue.
Make sure that `gem install sassc -v '2.4.0' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  bootstrap-email was resolved to 1.0.0.alpha4, which depends on
    sassc

Thanks in advance for the help. Let me know if you need more information.

I'm not familiar with the Mac ecosystem, but the error is definitely related to their specific compiler. Maybe they need some special build flags or the compiler version is simply outdated. Try to use a different one if possible.

Getting the same error on Debian running in WSL. OS: Windows 11 21H2 build 22000.556 WSL OS: Pengwin 11 v. 21.12.0 (basically Debian) Ruby version: 2.7.1 [x86_64-linux] Rails version: 6.1.4.6

It was building fine on Rails 5.2.2.1, started failing after upgrade to 6.1.

Alright, it was pretty easy to solve. If someone stumbles upon this, just run sudo apt install g++ and you're good to go. My error was a bit different from OP's though, a permission error.
