Rbenv 在 Capistrano 部署期间无法找到 Yarn

Question

我一直在使用 Capistrano 部署我的 Rails 应用程序。它在以下步骤中失败：

   01 $HOME/.rbenv/bin/rbenv exec bundle install --path /var/www/bubblin.io/shared/bundle --without development test --deployment --quiet
    ✔ 01 marvin@bubblin.io 1.053s
00:26 yarn:install
      01 $HOME/.rbenv/bin/rbenv exec yarn install --production
      01 rbenv: yarn: command not found

$HOME/.rbenv/bin/rbenv exec yarn install --production
      01 rbenv: yarn: command not found

我通过 ssh 连接到服务器并尝试了以下方法，它有效：

$ yarn install --production
yarn install v1.10.1
[1/4] Resolving packages...
success Nothing to install.
success Saved lockfile.
Done in 0.06s.

但是当我用 rbenv exec 作为相同命令的前缀时，它失败了。

$ rbenv exec yarn install --production
rbenv: yarn: command not found

所有依赖项似乎都已正确安装，但 rbenv 出于某种原因无法找到 yarn？

Answer 1

我认为 yarn 是 nodejs 包管理器，不应该运行通过 rbenv exec 吗？

因此，在这种情况下，您可以简单地从常规 shell 而不是 rbenv 中使用它。例如，尝试创建像下面这样的任务应该可以完成工作。

desc "Yarn Install"
task :yarn_install do
  on roles(:all) do |host|
    execute :yarn, :install, "--production"
  end
end

然后，运行它与 bundle exec cap production yarn_install

或者，从您拥有的另一个任务中调用该任务等。

更新：

如果不使用纱线，

在 Gemfile 中，删除或评论 'capistrano-yarn'

#gem 'capistrano-yarn'

在 Capfile 中，删除或评论 'capistrano/yarn'

#require 'capistrano/yarn'

创建新项目：

rails new <name> --skip-yarn

但是，在现有项目中，在应用环境文件中将 webpacker.check_yarn_integrity 设置为 false（即 app/config/development.rb app/config/production.rb）

config.webpacker.check_yarn_integrity = false

在app/views/*路径中找到javascript_pack_tag或stylesheet_pack_tag，然后注释掉它们，像这样：

<%# javascript_pack_tag "" %>
<%# stylesheet_pack_tag "" %>
