2 failures when trying to excute code on ruby on rails

Hi This is my code:

require 'spec_helper'

describe "Creating todo lists" do it "redirects to the todo list index page on success" do visit "/todo_lists" click_link "New Todo list" expect(page).to have_content("New todo_list")

    fill_in "Title", with: "My todo list"
    fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"


    expect(page).to have_content("My todo list")    
end

it "displays an error when the todo list has no title" do
    expect(TodoList.count).to eq(0)
    visit "/todo_lists"
    click_link "New Todo list"
    expect(page).to have_content("New todo_list")

    fill_in "Title", with: ""
    fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"

    expect(page).to have_content("error")
    expect(TodoList.count).to eq(0)

    visit "/todo_lists"
    expect(page).to_not have_content("This is what I'm doing today.")
end

end

When I run, it failed twice.

Failures:

1) Creating todo lists redirects to the todo list index page on success Failure/Error: expect(page).to have_content("New todo_list") expected to find text "New todo_list" in "New Todo List Title Description Text Back" # ./spec/features/todo_lists/create_spec.rb:7:in `block (2 levels) in <top (required)>'

2) Creating todo lists displays an error when the todo list has no title Failure/Error: expect(TodoList.count).to eq(0) TypeError: Cannot visit ThreadSafe::Array # ./spec/features/todo_lists/create_spec.rb:18:in `block (2 levels) in <top (required)>'

I'm very new to ruby on rails. Can someone help me out please?

So I also had these same problems as what many of you are having the steps that I took are the following:

Step 1,

Log into Terminal Navigate to ./treehouse/projects 

cd treehouse/projects

then run 

vagrant ssh

you are now logged into the VM

Step 2,

While in the VM, treehouse:~/projects/odot (master) $`

run bundle

make a git commit

Step 3,

Run bin/rails generate rspec:install

hit "Y" to force

git commit

Step 4,

Run bundle binstubs rspec-core --force

git commit

Step 5,

Run bin/rake db:migrate Run bin/rake db:migrate RAILS_ENV=test

git commit

Step 6,

Rewrite "create_spec.rb" using the video "Write out our first tests" and go from there.

This acts as a factory reset for the gems and whatnot you install in the other lessons that people like myself may have messed up. I had the same error messages as well.

This method worked for me and I was able to run the test with/without the proper failures that are shown in the video.

On a side note I went through the steps that terminal told me to use for solving this problem and it was a farce.

Spell check your "create_spec.rb" and make sure everything matches up in the video.
