ruby-on-rails - Ruby Heroku Buildpack 因 Dokku 失败

问题描述

我有一个 Rails 应用程序，我定期在 Heroku 上部署并且总是成功，我正在尝试使用 Dokku 将它迁移到 Digital Ocean。在 Heroku 上，我只安装了 nodejs 和 Ruby buildpacks（按此顺序），我所做的就是推送它。所以，我想我会用 Dokku 图像创建一个数字海洋，添加相同的构建包，并能够推送我的应用程序，但在部署过程中它失败了。这是我在 Digital Ocean 上创建 Droplet 后所做的：

ssh-add -k ~/.ssh/id_rsa
ssh root@123.123.123.123 (IP address of the Droplet)
# Now I have SSH'd into the droplet
dokku apps:create mytestapp
dokku buildpacks:add mytestapp https://github.com/heroku/heroku-buildpack-nodejs.git
dokku buildpacks:add mytestapp https://github.com/heroku/heroku-buildpack-ruby.git
exit
# Now I've exited back into my local machine
git remote add dokku dokku@123.123.123.123:mytestapp
git push dokku master

这是我推送后得到的输出：

       This is most likely a temporary internal error. If the problem
       persists, make sure that you are not running a custom or forked
       version of the Heroku Ruby buildpack which may need updating.

       url: https://s3-external-1.amazonaws.com/heroku-buildpack-ruby/production/ruby-2.6.6.tgz
remote: /tmp/buildpackuip6D/bin/compile: line 31: /tmp/tmp.zjpwB97bqO/bin/ruby: No such file or directory
To 123.123.123.123:mytestapp
 ! [remote rejected] master -> master (pre-receive hook declined)

它似乎无法下载 Ruby buildpack，但下载 Node buildpack 的第一步完成得很好。这些与 Heroku 使用的构建包相同，我也可以curl在本地机器上使用 Ruby 构建包curl https://s3-external-1.amazonaws.com/heroku-buildpack-ruby/production/ruby-2.6.6.tgz -o file。使用 Dokku 从 Heroku 切换到 Digital Ocean 似乎应该很容易。有人可以帮我弄清楚我做错了什么吗？
