$ brew install phantomjs

will fail with error if you are using MacOSX El Capitan

$ brew install phantomjs phantomjs: This formula either does not compile or function as expected on OS X versions newer than Yosemite due to an upstream incompatibility. Error: An unsatisfied requirement failed this build.

To fix it just do Homebrew/legacy-homebrew#44535 (comment)

I am trying to install ruby, rails and git via the provided link at railsinstaller.org. Link does not seem to be working.

In Ubuntu, the "chrome" command is "google-chrome", so if you execute the install script it will fail.

I ran the specified rails package installer 'railsinstaller-3.2.0.exe' and everything seemed to install fine. However when I did the recommended command line actions to check the versions, only GIT and Ruby installed. Rails commands are not recognized.

I am receiving an issue when creating the first test file, it says:

An error occurred while installing bootsnap (1.4.2), and Bundler cannot
continue.
Make sure that gem install bootsnap -v '1.4.2' --source 'https://rubygems.org/' succeeds before bundling.

This is on an iMac High Sierra, ca 2018.

When running 'rbenv install 2.2.3' in the Terminal I get:

'WARNING: ruby-2.2.3 is past its end of life and is now unsupported.

It no longer receives bug fixes or critical security updates.'

Presumably this means we should be using a newer version of ruby. What version should we use, if any? What is the correct terminal command to use? And can y'all update the installation git?

At the start of the lecture, there is a mention of Docker Images. How do I use them and and scripts to build virtual images of the Ubuntu system?

I get this message when I am trying to install Rails.

ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

the apt-get update -y fails

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update -y
sudo apt-get install -y nodejs

is it possible to just install a gem of node?

Hi guys, I don't know what is the problem:

It says site can not be reached. Not sure what yet wrong. Recommendations on what I should check?

I did:
$ rails new test_app
$ rails server

Doesn't work.

provide example of how to set an environment variable
echo 'export RECIPEPUPPY_HOSTPORT=www.recipepuppy.com:80' >> ~/.bashrc
set +e
source ~/.bashrc
set -e
echo $RECIPEPUPPY_HOSTPORT
chrome http://$RECIPEPUPPY_HOSTPORT---- im unable to launch chrome after this ,can plz look into this issue. im using ubuntu 16.04 lts

The url assigned to the WEB_URL environment variable should be 'coursera.org', not 'coursera.com'
