如何将 Tailwind 2.0 安装到现有项目 (rails 6.1)

Question

我正在尝试将 Tailwind 2.0 安装到现有项目（rails 6.1）但出现错误：

如何在现有 Rails 项目（6.1 和 sprocket）上安装 Tailwind 2.0

在我的 gemfile 中我添加了：

gem "webpacker", github: "rails/webpacker", ref: 'b6c2180'

app/javascript/application.js

import Rails from "@rails/ujs"
import Turbolinks from "turbolinks"
import * as ActiveStorage from '@rails/activestorage';
import '../utils/direct_uploads.js';
require("app/javascript/stylesheets/application.css")
Rails.start();
Turbolinks.start();
ActiveStorage.start();

app/views/layouts/application.html.erb：

<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

在文件夹 app/javascript/stylesheets/

app/javascript/stylesheets/application.css

@import "tailwindcss/base";
@import "tailwindcss/components";
@import "tailwindcss/utilities";

文件tailwind.config.js

并且已经运行 rails webpacker:install 和 rails s 但得到一个错误：

Webpacker::Manifest::MissingEntryError - Webpacker can't find application.css in /Users/ben/code/Tioneb12/postgis/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
  "entrypoints": {
  }
}

我正在尝试：

rails asset:clobber
yarn
rails asset:precompile

并得到另一个错误：

只需删除为我工作的文件夹tmp/cache/assets ;)
