Are you tired of wrestling with Wpscan on your macOS using Homebrew, only to be met with frustrating Nokogiri and Bundler issues? Fear not, dear reader! In this comprehensive guide, we’ll walk you through the troubleshooting process, providing clear and direct instructions to get Wpscan up and running smoothly on your Mac.
Understanding the Issue
Before we dive into the solutions, it’s essential to understand the root cause of the problem. Wpscan, a popular WordPress security scanner, relies on Nokogiri, a Ruby gem, to function correctly. However, when installed using Homebrew, Nokogiri can sometimes clash with the system’s Ruby version, leading to Bundler issues and rendering Wpscan unusable.
The Symptoms
If you’re experiencing any of the following symptoms, this guide is for you:
- Nokogiri installation fails with a “Failed to build gem native extension” error
- Bundler reports a “Could not find nokogiri-1.x.x in any of the sources” error
- Wpscan installation or execution results in a “Error: Nokogiri is not installed” message
Step 1: Update Homebrew and Ruby
The first step in resolving the issue is to ensure you’re running the latest versions of Homebrew and Ruby.
brew update
brew upgrade rubyThis command will update Homebrew and upgrade Ruby to the latest version available.
Step 2: Uninstall and Reinstall Nokogiri
Next, we’ll uninstall and reinstall Nokogiri to ensure a clean installation.
gem uninstall nokogiri
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/usr/local/opt/libxml2/include/libxml2The `–use-system-libraries=true` flag tells Nokogiri to use the system’s libxml2 library, which is often the source of conflicts. The `–with-xml2-include` flag specifies the location of the libxml2 include files.
Step 3: Update Bundler and Wpscan
With Nokogiri reinstalled, it’s time to update Bundler and Wpscan.
gem update bundler
brew reinstall wpscanThis will ensure that Bundler is using the latest version of Nokogiri and that Wpscan is reinstalled with the correct dependencies.
Step 4: Verify Wpscan Installation
Finally, let’s verify that Wpscan is installed correctly and functioning as expected.

Q: Why am I getting an error with nokogiri when trying to run wpscan on macOS?
