Have you read and handled this note in the installation instructions? Note using v8.h and compiling MiniRacer requires a C++11 standard compiler, more specifically clang 3.5 (or later) or gcc 4.8 (or later). github.com/discourse/mini_racer#installation – Wise

I have tried many solution stackoverflow..... But issue still remains – Lenitalenitive

Yes. This isn't a stack overflow link, though. This is a link to the actual documentation for the gem you're trying to install. – Wise

okay, I tried with this ..... thanks – Lenitalenitive

no it's not working on my mac 10.14 – Lenitalenitive

Have you installed the xcode command line tools? xcode-select --install – Nitroparaffin

Yes already latest version xcode-select installed – Lenitalenitive

Answer 1

Problem solve after change mini_racer gem version

mini_racer (0.2.1)

Lenitalenitive

Can you change your mini racer version according to your rails – Lenitalenitive

Answer 2

I ran into the exact same issue on OS X Mojave with exact same stack trace as above. The following solution fixed it for me: (Credit to author of this blog Dave Kimura): https://blog.driftingruby.com/updated-to-mojave/ Solution was simply:

1. Make sure you have installed xcode tools (skip if already done)

   xcode-select --install

2. Now run the following command and follow the on-screen installer

   open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

That's it. Now mini_racer should install happily.

Answer 3

In docker-compose with Docker image like ruby, you can try:

1. Delete Gemfile.lock inside image
2. Run bundle install again.

Answer 4

In case someone runs into this issue, I solved it after specifying the version in the gemfile.

gem 'mini_racer', '>=0.2.1'
