       The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

您好，我担心这是一个我非常不熟悉的领域，所以我可能不擅长提出正确的问题。

我有一个 Ruby on Rails 项目部署在 ubuntu 服务器 + S3 上进行存储。我刚刚执行了 yarn upgrade 和 bundle update 来处理一些安全依赖。当我将我的应用程序部署到服务器（git push dokku master）时，我收到了上述错误。

我的应用程序中没有 Node.js……据我所知（如果我在全局范围内搜索“node.js”或“nodejs”，我没有找到）。

我认为我的服务器上没有它？但我不确定……

我发现另一个人在 2020 年 6 月 14 日开始在网上谈论这个问题 (https://www.guj.com.br/t/heroku-com-node-incompativel/405283)，所以这可能是新事物。

我的应用程序是 Rails 6，在边缘分支上运行。

我不知道如何继续。

更新：正如@engineersmnky 指出的，这是一个 buildpack 错误...

现在我的服务器上没有指定的构建包（只有默认的构建包？在我的 rails 应用程序中？不确定）。

我正在使用 Dokku，它使用 Heroku 构建包。默认的 rails one 运行节点 10.15.3 (https://devcenter.heroku.com/changelog-items/1657)，与给我带来麻烦的版本相同...

Heroku 建议添加多个构建包 (https://devcenter.heroku.com/articles/ruby-support#installed-binaries)，一个首先安装 nodejs，一个执行 ruby。

$ heroku buildpacks:add heroku/nodejs
$ heroku buildpacks:add heroku/ruby

问题 1

如果我用 dokku 做这个，我会写：

$ dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-nodejs.git
$ dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-ruby.git

（参见：http://dokku.viewdocs.io/dokku/deployment/methods/buildpacks/#adding-custom-buildpacks）

问题 2

然后它说我需要更新我的 package.json 文件，并添加如下内容：

“完成此操作后，您需要在应用的根目录中创建一个 package.json 文件。例如，要安装 8.9.4 版，您的 package.json 可能如下所示：

{ "engines" : { "node": "8.9.4" } }

如果我已经有一个 package.json 文件，我可以简单地更新它来更新我的 buildpack 吗？还是我需要做上面的第 1 步？（问题1的答案）？

我当前的 package.json 是：

{
  "name": "taaalk_edge",
  "private": true,
  "dependencies": {
    "@rails/actioncable": "^6.0.0",
    "@rails/actiontext": "^6.0.2-1",
    "@rails/activestorage": "^6.0.0",
    "@rails/ujs": "^6.0.0",
    "@rails/webpacker": "4.2.2",
    "trix": "^1.0.0",
    "turbolinks": "^5.2.0",
    "websocket-extensions": "0.1.4"
  },
  "version": "0.1.0",
  "devDependencies": {
    "webpack-dev-server": "^3.10.1"
  }
}

问题 3

我读到有一个.nvmrc 文件...https://github.com/nvm-sh/nvm#nvmrc

哪个可以指定节点版本...但前提是我安装了 nvm？但我不知道我是否可以在服务器上安装它。

【问题讨论】：

如果你使用yarn，你肯定有node（这是一个先决条件）。您需要做的是更新服务器上的node 以满足最低要求。你如何去做取决于服务器上已有的东西。我通常推荐nvm 作为包管理器，但您也可以直接从其他包管理器安装/升级节点，例如apt、yum 等。Here 是在各种情况下安装/更新节点的好指南。
谢谢@engineersmnky。这可能是一个愚蠢的问题，但我可以在我的服务器上安装 nvm 吗？（不仅仅是我的本地计算机）
由于服务器是ubuntu，本指南可能有助于安装nodejs github.com/nodesource/distributions/blob/master/…。如果只有 1 个版本的 nodejs，你可能不需要 nvm
@duykhoa，谢谢.. 有点奇怪，但我无法在我的服务器上运行 node -v （在我升级之前）。我有点惊讶，因为该应用程序到目前为止一直运行良好（使用 webpacker）
嗯，我安装了它......关键时刻......现在部署

标签： node.js ruby-on-rails deployment webpacker dokku

【解决方案1】：

目前（2021 年 3 月）heroku buildpack 似乎只包含 node v10.15.3，而当前的 webpacker 5（rails 6.1.1 附带）需要 Node.js ">=10.17.0"。

对于我们的项目，我可以通过恢复到 webpacker 4.2.2 来解决这个问题。

Webpacker 是 node 和 ruby 之间的桥梁，你需要一个 gem 和一个包，并且需要设置两次版本：

Gemfile 设置 ruby 的版本 gem 'webpacker', '~> 4.2.2'
package.json 设置节点 "@rails/webpacker": "4.2.2" 的版本

附言还没有解决方案：heroku 提供了一个带有正确节点版本的 buildpack 一段时间，但回滚了：https://devcenter.heroku.com/changelog-items/1818

【讨论】：

【解决方案2】：

这不是答案，我只是把问题中的字符数加满了……

更新问题 2

我尝试通过添加“引擎”来更新我的 package.json 文件：

{
  "name": "taaalk_edge",
  "private": true,
  "dependencies": {
    "@rails/actioncable": "^6.0.0",
    "@rails/actiontext": "^6.0.2-1",
    "@rails/activestorage": "^6.0.0",
    "@rails/ujs": "^6.0.0",
    "@rails/webpacker": "4.2.2",
    "trix": "^1.0.0",
    "turbolinks": "^5.2.0",
    "websocket-extensions": "0.1.4"
  },
  "version": "0.1.0",
  "devDependencies": {
    "webpack-dev-server": "^3.10.1"
  },
  "engines": {
    "node": ">=10.17.0"
  }
}

这不起作用...虽然我的错误发生了变化：（我转移到我的暂存环境，所以我不会破坏我的服务器...-在此更改之前我在暂存中遇到了同样的错误。）

我的下一个计划是添加新的构建包。

进一步更新...

我添加了新的构建包，它已部署，但应用在 heroku 上崩溃。

我试图解决这个问题：

https://dev.to/lawrence_eagles/causes-of-heroku-h10-app-crashed-error-and-how-to-solve-them-3jnl#:~:text=This%20error%20is%20thrown%20if,App%20crashed%20error%20code%20message.

但没有运气......

更新

现在正在研究heroku。它崩溃了，因为我没有在 heroku 上设置 ENV 变量。

是时候更新我的 dokku 构建包了。

【讨论】：

你是怎么解决的？哪个 ENV 变量影响节点版本？

【解决方案3】：

我遇到了同样的错误，然后我这样做了：-

我使用命令安装节点

nvm install 10.17.0

nvm 是 节点版本管理器

然后使用命令来使用它

nvm use 10.17.0

现在终于用这个命令了

rails webpacker:install

就我而言，它有效。

【讨论】：

这是在本地运行应用程序的解决方案，而不是在 dokku 上
