这是我的 Gemfile 的外观：

source :rubygems
gem 'sinatra'
gem 'json'
gem 'tiny_tds'

将应用推送到 Heroku 的输出：

在我的本地主机上运行完美。我尝试删除存储库并创建一个新存储库，或者重新启动 heroku。我如何在heroku上安装tiny_tds？怎么了？

发生此错误是因为您的 dyno 缺少 freetds 库。使用这样的库需要使用自定义 buildpack。互联网上有很多开源构建包。例如https://github.com/firmhouse/heroku-buildpack-ruby-freetds。

我猜你已经使用 C 构建开关在本地机器上安装了 TinyTDS gem，但没有通过 Bundler 指定。您是否在本地主机上沙箱安装？例如

bundle install --binstubs --path=vendor

看看这是否有效。我猜它应该会失败，因为现在无法访问项目之外的其他 gem。然后使用TinyTDS README 中建议的构建开关bundle config安装FreeTDS
