[英]Gem not available in Rails app but works fine in Rails console (IMGKit)
[英]imgkit gem not working on heroku in rails application
嗨,我有一個小應用程序正在使用imgkit從某些文本生成png。 我的報價模型中的每個報價都使用imgkit創建png版本
應用程序/控制器/ quotes_controller.rb
def show
respond_to do |format|
format .html
format.png do
kit = IMGKit.new render_to_string, width: 1080, height: 1080
send_data kit.to_png, type: "image/png", disposition: "inline"
end
end
end
它在我的本地計算機上運行良好,但是當我上傳到heroku imgkit時停止工作。
我嘗試將二進制文件添加到gem文件中,如下所示:
source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
ruby '2.6.0'

end
group :development do

end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
不幸的是,這沒有用。
然后,我按照https://github.com/csquared/IMGKit#heroku上的說明進行操作
並從https://github.com/wkhtmltopdf/obsolete-downloads/blob/master/README.md#linux下載了10.0版本
我將文件添加到bin / wkhtmltoimage-amd64,並添加了文件config / initializers / imgkit.rb
該文件的以下代碼
IMGKit.configure do |config|
config.wkhtmltoimage = Rails.root.join('bin', 'wkhtmltoimage-amd64').to_s if ENV['RACK_ENV'] == 'production'
end
我進行了測試,發現它沒有用,並且我不斷得到
IMGKit::NoExecutableError (No wkhtmltoimage executable found at /app/bin/wkhtmltoimage-amd64
誰能為我指出正確的方向,如果您需要更多信息,請告訴我
您已在app/bin/wkhtmltoimage-amd64
處添加了二進制文件,但您要指定Rails.root.join('bin', 'wkhtmltoimage-amd64')
,即bin/wkhtmltoimage-amd64
。
或
bin/wkhtmltoimage-amd64
,或 Rails.root.join('bin', 'wkhtmltoimage-amd64')
更改為Rails.root.join('app', 'bin', 'wkhtmltoimage-amd64')
。 我建議使用第一個選項,因為在bin/
中的根目錄有二進制文件是更典型的選擇。
