Problem installing rmagick gem on Heroku

由 江枫思渺然 提交于 2019-12-13 07:29:25
问题 I'm trying to push a Rails app to Heroku, but it's failing when it tries to build the rmagick gem (which is specified in the Gemfile). I've done bundle install locally and the app runs fine. But, on Heroku in the pre-receive hook, after it build the rmagick examples, I get: make install /usr/ruby1.8.7/bin/ruby setup.rb install rm -f InstalledFiles ---> lib mkdir -p /disk1/tmp/build_3eu8mw7r34j0f/.bundle/gems/ruby/1.8/gems/rmagick-1.15.17/lib install RMagick.rb /disk1/tmp/build_3eu8mw7r34j0f/

How to get image type with RMagick?

由 依然范特西╮ 提交于 2019-12-13 02:24:34
问题 I need to find the real type of images, as a lot of times they come with the wrong extension. Is this possible with RMagick? How? 回答1: Solution: image.format # 回答2: if you want more generic solution (on linux): require "open3" def File.sys_file_cmd(path) if File.exist? path stdin,stdout,stderr = Open3.popen3(%{file --mime -b "#{path}"}) file_err = stderr.gets file_out = stdout.gets if file_err raise Exception, "The 'file' command error: #{file_err} : with #{path}" end if file_err.nil? && (

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 应用RailsInstaller进级到Ruby 1.9.2并应用Rails3.1后发明无法安装rmagick. 首要原因有两个： 本来安装的ImagickMagick没有包含development headers，也就是在ImgickMagick安装目次下没有lib以及include这两个文件夹。 安装rmagick的时辰没有指定响应的lib路径。 首要参考这个连接： http://stackoverflow.com/questions/5811388/imagemagick-core-rl-magick-dll-not-found-or-how-to-install-rmagick-on-windo 我应用下面的步调成功安装： 一个新版本的imageMagic: http://image_magick.veidrodis.com/image_magick/binaries/ 我是了此中的“ImageMagick-6.6.1-10-Q16-windows-dll.exe” 安装上方的新版本的imagemagick到一个不包含空格的路径下，并重视 安装过程中必然要选择包含headers.和参加path两项。 原有的imagemagick不删除也没有关系，因为新版本的路径会在老版本的前面，所以默认会应用新的版本。
