Question

我正在推送一个我几个月没有更新的应用程序，并且遇到了这个问题。我只在代码中更改了一些变量。不知道为什么它突然这样对我。

Answer 1

可以在heroku支持页面上找到资产重新编译问题的最常见原因here。

根据错误消息中提到的Postgres，我会尝试将config / application.rb中的以下行更改为 false ，如下所示：config.assets.initialize_on_precompile = false。

Answer 2

您应该通过确保config / application.rb中包含以下行来阻止初始化您的应用程序并连接到数据库：

config.assets.initialize_on_precompile = false

预编译资产失败
