我在我的第一个 Elixir 项目中使用 mix ecto.create 时遇到错误

Question

当我混合 ecto.create 时，出现以下错误：

could not compile dependency :mint, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile mint --force", update it with "mix deps.update mint" or clean it with "mix deps.clean mint"

我尝试重新安装一切！也许postgresql有问题？

Answer 1

当您使用

mix phx.new test

创建新的 Phoenix 项目时，您只需从该目录运行终端中显示的命令。您应该在终端中看到并遵循此操作：

我们快到了！缺少以下步骤： 获取并安装依赖项？ [嗯]

（我第一次直接输入“Y”而不是

mix deps.get

）

$ cd test
$ mix deps.get

然后在 config/dev.exs 中配置数据库并运行：

$ mix ecto.create

启动您的 Phoenix 应用程序：

$ mix phx.server

您还可以在 IEx（Interactive Elixir）中运行您的应用程序，如下所示：

$ iex -S mix phx.server

如果还不行，请重新安装Phoenix。

希望对你有帮助！
