How to install it on Windows or MacOS

[pharazone]

I use these two platforms, and I can not installed it on my PC/MAC. So how can I install it? Thank you.

Visit https://github.com/urbanadventurer/WhatWeb/wiki/Installation for installation instructions.

Alternatively:

git clone https://github.com/urbanadventurer/WhatWeb
bundle install

[pharazone]

I followed the URL for installation, but it didn't work…… I can't launch it with "./whatweb" command.

One of the dependencies is failing to install as per the output.

You might have luck with bundle install --without test

Alternatively, the Ruby environment is more friendly on Mac.

I followed this command, but when I typed "whatweb", still nothing.....

Here's my log.

You can also use it via docker:

docker run --tty --interactive --rm guidelacour/whatweb \
   ./whatweb nonexistent.domain

from https://hub.docker.com/r/guidelacour/whatweb/

Hello World,

For me its working using theses step (Macos 10.6) after git clone whatweb 👍 1: cd whatweb 2: \curl -sSL https://get.rvm.io | bash -s stable --ruby (Install RVM stable with ruby) 3: * To start using RVM you need to run source /Users/test/.rvm/scripts/rvm 3.1: source /Users/test/.rvm/scripts/rvm 4: bundle install --without test 5: ./whatweb yourtarget.com

In macOS Catalina the default version of Ruby bundled with macOS won't build gems like json. You will see errors like this.

An error occurred while installing json (2.3.1), and Bundler cannot continue.
Make sure that `gem install json -v '2.3.1' --source 'https://rubygems.org/'` succeeds before bundling.

To solve the problem install your own version of Ruby. I recommend rbenv over rvm, but either is fine.

brew install rbenv ruby-build
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile 
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.zshrc 
rbenv install 2.6.5
rbenv global 2.6.5

Next verify that you have ruby installed. If you see the following it worked.

ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-darwin19]

Now bundle install should succeed.

bundle install
