Rails新手，过去几个小时一直在努力解决此语法错误

我相信问题出在控制器代码上。

我收到以下错误：

"app/controllers/places_controller.rb:74: syntax error, unexpected keyword_end, expecting end-of-input"

以前，一切都很好。我进行了迁移，以使其可与回形针宝石一起使用。我一直在github页面上的说明。我还更新了模型（我注释掉了模型代码，但仍然遇到相同的错误）。这使我相信，问题出在控制器本身。

有趣的是，以前使用相同的代码，控制器可以正常工作，但现在却不行。我已在下面附加了完整的控制器代码。

pclass PlacesController < ApplicationController
before_action :set_place, only: [:show, :edit, :update, :destroy]

# GET /places
# GET /places.json
def index
@places = Place.all
end

# GET /places/1
# GET /places/1.json
def show
end

# GET /places/new
def new
@place = Place.new
end

# GET /places/1/edit
def edit
end

# POST /places
# POST /places.json
def create
@place = Place.new(place_params)

respond_to do |format|
  if @place.save
    format.html { redirect_to @place, notice: 'Place was successfully created.' }
    format.json { render :show, status: :created, location: @place }
  else
    format.html { render :new }
    format.json { render json: @place.errors, status: :unprocessable_entity }
  end
end
end

# PATCH/PUT /places/1
# PATCH/PUT /places/1.json
def update
respond_to do |format|
  if @place.update(place_params)
    format.html { redirect_to @place, notice: 'Place was successfully updated.' }
    format.json { render :show, status: :ok, location: @place }
  else
    format.html { render :edit }
    format.json { render json: @place.errors, status: :unprocessable_entity }
  end
 end
end

# DELETE /places/1
# DELETE /places/1.json
def destroy
@place.destroy
respond_to do |format|
  format.html { redirect_to places_url, notice: 'Place was successfully destroyed.' }
  format.json { head :no_content }
end
end

private
# Use callbacks to share common setup or constraints between actions.
def set_place
  @place = Place.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def place_params
  params.require(:place).permit(:name, :description, :rating, :images)
end
end
