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

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 Maybe they need some special build flags or the compiler version is simply outdated.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.

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.

I got the same error with:

• rails 7.1.4
• sass-rails (6.0.0)
• ruby 3.1.2
• MacOS Sequoia (Version 15.0)
• libsass and gcc already installed via brew

[AJ-Ayush]

same here. Did you find any fix @dangquangthai ?

[dangquangthai]

@AJ-Ayush I resolved this by deleting the directory /Library/Developer/CommandLineTools/ on my iMac. After that, It automatically installs the new dev tool and then run bundle install

[crnastena]

My issue was with how ruby was built when installing it with asdf. Two different versions of ruby had different output for compilers:

# ruby 3.3.3 compiler check
ruby -rrbconfig -e'p RbConfig::CONFIG["CC"]' -e'p RbConfig::CONFIG["CXX"]'
"usr/bin/clang"
"false"

# ruby 3.3.4 compiler check
ruby -rrbconfig -e'p RbConfig::CONFIG["CC"]' -e'p RbConfig::CONFIG["CXX"]'
"clang"
"clang++"

After some searching I came across ruby-build, which is used by asdf-ruby plugin, and ability to specify compiler paths. So I reinstalled ruby:

asdf uninstall ruby 3.3.3
CC="clang" CXX="clang++" asdf install ruby 3.3.3

After that sassc was built properly.

I am not sure how this works with different ruby managers like rvm and rbenv.

This also works for me, thanks. 🙏🏾 And installation via rbenv is as same as asdf (rbenv uses ruby-build to install specific version ruby too).

@crnastena Do you know what the equivalent would be for rvm ? I am running into the same issue

@shellandbull RVM seems to provide the --with-gcc option. maybe you can give it a try.

@AJ-Ayush I resolved this by deleting the directory /Library/Developer/CommandLineTools/ on my iMac. After that, It automatically installs the new dev tool and then run bundle install

This fixed for me.

Though I did:

• rm -rf /Library/Developer/CommandLineTools/
• xcode-select --install
• rbenv install 3.3.4
• bundle install
