Ruby - Webpacker 找不到应用程序

Question

安装设备 gem 后，我遇到了错误。我该如何解决这个问题：

Webpacker can't find application in /home/grkmdgn06/Desktop/my5_homework/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:
{
}

提取的源代码（第 9 行附近）： ...

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

...

Answer 1

也许你的 node.js 已经过时了

试试这个：

sudo npm install n -g

sudo n stable

bundle exec rake webpacker:install
