它在我的本地机器上运行良好,但当我上传到heroku时,它停止工作
我尝试将二进制文件添加到gem文件,如下所示:

我测试了一下,发现它不起作用了,我一直在得到答案
IMGKit::NoExecutableError(在/app/bin/wkhtmltoimage-amd64中找不到wkhtmltoimage可执行文件
有人能给我指出正确的方向吗?如果您需要更多信息,请告诉我。您已经在app/bin/wkhtmltoimage-amd64
添加了二进制文件,但您指定的是Rails.root.join('bin','wkhtmltoimage-amd64')
,即bin/wkhtmltoimage-amd64
或者
- 将二进制文件移动到
bin/wkhtmltoimage-amd64
,或
- 将
Rails.root.join('bin',wkhtmltoimage-amd64')
更改为Rails.root.join('app','bin','wkhtmltoimage-amd64')
我推荐第一个选项,因为在bin/
hi@fphilipe的根目录下有二进制文件更为典型。非常感谢您的回答……很好的发现……我真的很感谢您的回答time@JoeBloggs这个实现仍然有效吗?我试过了,但是得到了一个空白的白色图像。@sunny自从我玩这个游戏以来,它一直是一个黑色的这个应用程序。你为什么不多解释一下你的问题呢?我确信这是一个打字错误,经过深入研究,我们可以找到问题的症结所在
IMGKit.configure do |config|
config.wkhtmltoimage = Rails.root.join('bin', 'wkhtmltoimage-amd64').to_s if ENV['RACK_ENV'] == 'production'
