背景

我正在将旧版 LiveView 应用程序移植到最新版本的 Phoenix (v1.6.5)。总的来说，我对整个事物都是新手，我希望能够运行mix phx.new web_interface --live --no-ecto并找到与以前相似的结构：

├───assets
│   ├───css
│   ├───js
│   └───static
│       └───images
├───config
├───lib
│   ├───web_interface
│   └───web_interface_web
│       ├───channels
│       ├───live
│       ├───templates
│       │   └───layout
│       └───views
└───priv
    └───static
        └───assets

相反，我得到了：

├───assets
│   ├───css
│   ├───js
│   └───vendor
├───lib
│   └───web_interface
│       ├───controllers
│       ├───templates
│       │   ├───layout
│       │   └───page
│       └───views
└───priv
    ├───gettext
    │   └───en
    │       └───LC_MESSAGES
    └───static
        ├───assets
        └───images

缺了点什么

密切注意您现在会看到我缺少几个重要的文件夹，即web_interface_web和live文件夹。

所以现在我明白了我错过了一个巨大的里程碑升级或者我的mix phx.new命令有问题的印象。

问题

  • 为什么这些文件夹不见了？
  • 如何移植项目？现在等效的文件夹是什么？

如果您在 Elixir 1.13 和 Phoenix 1.6.5 上运行，那么根据您提供的命令，应该有一个web_interface和目录（我把该命令的输出放在下面）。在您使用类似的东西生成第一个 LiveView 视图之前，不会创建该目录web_interface_webmix phx.new web_interface --live --no-ectolivemix phx.gen.live Accounts User users name:string age:integer

这看起来像旧版本的 Phoenix 或 Elixir。您可能在引用不同版本的 Elixir 或 Phoenix 的不同 shell 会话中生成了项目。另外，凤凰的哪个版本mix.exs说的？

检查您的 Elixir 版本elixir --version

➜  projects$ elixir --version
Erlang/OTP 24 [erts-12.0.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit] [dtrace]

Elixir 1.13.0 (compiled with Erlang/OTP 24)

然后检查phx您安装的软件包的版本mix archive

➜  projects$ mix archive      
* hex-1.0.1
* phx_new-1.6.5
Archives installed at: /Users/cj1/.kiex/mix/archives/elixir-1.13.0

如果您需要重新安装 phx 包，请运行 ( mix archive.install hex phx_newdocs )

➜  projects$ mix archive.install hex phx_new

Fetch and install dependencies? [Yn] y
* running mix deps.get
* running mix deps.compile

We are almost there! The following steps are missing:

    $ cd web_interface

Start your Phoenix app with:

    $ mix phx.server

You can also run your app inside IEx (Interactive Elixir) as:

    $ iex -S mix phx.server
