构建 Phoenix 应用程序的 exrm 版本时的回溯

Question

在将我的 Phoenix 应用程序目录从我的 Macbook SCP-ing 到我的 Fedora 虚拟机后，我尝试构建一个生产 exrm 版本，但引发了异常：

我对 Erlang、Elixir 和 Phoenix 完全陌生，所以我真的不知道如何解决这个问题。

Answer 1

https://github.com/bitwalker/exrm/issues/107 有一些讨论，通过使用不同的 Erlang 安装解决了这个问题。这对我来说看起来不是一个好方法。因此，根据其他人的建议，我尝试与之一起跑步

mix release --verbosity=verbose

这让我得到了更多信息，包括以下错误：

===> Provider (resolve_release) failed with: {error,
                                                {rlx_prv_release,
                                                 {failed_solve,
                                                  {unreachable_package,
                                                   phoenix_live_reload}}}}

所以在我的情况下 phoenix_live_reload 导致了问题。我从我的 mix.exs 的应用程序和 deps 函数中删除了 phoenix_live_reload（我不想将它包含在生产中），然后它成功地为我构建了版本。
