安装 Webpacker 后，Ruby on rails 5.2 崩溃答案

【问题标题】：Ruby on rails 5.2 crashes after installing Webpacker安装 Webpacker 后，Ruby on rails 5.2 崩溃
【发布时间】：2021-01-14 20:59:50
【问题描述】：

如果有人可以查看我在安装 Webpacker gem 后遇到的这个问题，我将不胜感激

我在 ruby "2.5.1" 上使用 Rails 5.2.4.3 并尝试从 Sprockets 切换到 Webpacker gem 来管理我的 JS（Vue 应用程序）、css 和其他资产...

我已经安装了 gem 没有任何问题。 gem 解析为webpacker (5.2.1)。

我还按照 webpacker 的说明运行了bundle exec rails webpacker:install...

尽管如此，现在当我尝试使用这三个 foreman、rails s 或 overkill 中的任何一个来运行我的服务器时，我在控制台中收到了一个奇怪的错误，并且它会因这条宿命消息而崩溃:) :

您可能在 Ruby 解释器或扩展中遇到了错误图书馆

这是我启动服务器后得到的日志：

更新

我试过了：

将 Ruby 升级到 2.7.2
我已将 Webpacker 降级到 3.6

但它不起作用......

更新 2

在谷歌搜索之后，我发现这与 2 个或更多需要原生 C 扩展的 gem 产生的冲突有关。

就我而言，在注释掉 gem pry-byebug 之后，我设法启动了我的服务器而没有崩溃，我终于让 Webpacker 为资产提供服务。

要找出导致您的案例出现问题的 gem：

bundle show --paths | ruby -e "STDIN.each_line {|dep| puts dep.split('/').last if File.directory?(File.join(dep.chomp, 'ext')) }"

这将为您提供需要原生 C 扩展的 gem 列表。

现在，评论和捆绑，直到你找到罪魁祸首

更新 3 - 仍未解决

尽管我设法启动了服务器并启动并运行了 webpack，但它仍然不时崩溃...

这可能与在开发环境中运行./bin/webpack-dev-server有关，但崩溃似乎很随机......

太奇怪了：/

很遗憾我不会写cmets，我会用答案表来帮助你。

代码中指示错误的行是 a

[1;38;5;2mweb   [0m | /Users/luka/.rvm/gems/ruby-2.5.1@trasteros/gems/listen-3.0.8/lib/listen/record/entry.rb:46: [BUG] Segmentation fault at 0x00000001068d3a7c

这确实表明 gem 与您的 Ruby 版本不兼容，或者用于安装 Ruby 的 c 编译器存在问题。

请进行广泛的研究以寻找“Ruby [BUG] 分段错误” 谢谢！

嗨@LE-HU，确定这是我搜索的第一件事，但我找不到与Webpacker相关的任何东西......问题是没有任何gem可能导致的痕迹问题所以我猜是 Webpack ......我会尝试将我的 webpack gem 锁定到以前的版本广告/或升级我的 ruby 安装，看看它是否有帮助。
