需要解决捆绑程序错误“您必须提供 exec_name (ArgumentError)”的解决方案答案

【问题标题】：Need a solution for bundler error "you must supply exec_name (ArgumentError)"需要解决捆绑程序错误“您必须提供 exec_name (ArgumentError)”的解决方案
【发布时间】：2020-05-03 14:32:22
【问题描述】：

最近的 OS X Mojave 更新弄乱了我的开发环境。由于与 openssl 冲突，mysql2 gem 停止工作，我的应用程序无法访问数据库。经过一些工作，我让它们运行，除了一个。我从 bundler 收到了这个奇怪的错误：

您必须提供 exec_name (ArgumentError)

Google 搜索不会返回太多。我可以找到它来自的代码行，但我无法确定原因。似乎没有正确传递参数。有没有人遇到过这个错误？你有解决办法吗？

我正在运行 OS X Mojave 10.14.6、brew、apache、rbenv、Phusion Passenger、bundler 2.1.4。我最初使用的是 Ruby 2.5.1 并尝试了 2.5.2，但并没有什么不同。

这是完整的输出：

【问题讨论】：

这似乎是捆绑程序错误，您的捆绑程序版本是否已更改？我有时会收到 Heroku 的警告，说我的捆绑程序已更新，如果我遇到问题，我应该尝试回到旧版本。还是重新安装 bundler 并重新构建？
您的问题必须包含重现问题的步骤。在这种情况下，你是说你从 bundler 中得到了一个给定的错误，但你实际上是如何得到这个错误的呢？ bundler 做了很多事情——直到你包括（至少）你输入的实际命令来生成这个错误，我不确定有人能帮助你。
我确实尝试了一些不同版本的 Bundler，但我收到了相同的错误消息。 Bundler 2.1.4 可以在我拥有的其他开发计算机上运行，所以我很困惑为什么这台会出现问题。至于复制这个问题，这是一个非常基本的 Rails 应用程序。我已经列出了软件版本，但我认为我的系统有一些特定的东西坏了。为什么一个 Rails 应用程序有效，而另一个无效，这很奇怪。我可能最终会重新安装操作系统并从零开始。这一切都是因为 Mojave 更新而发生的，所以谁知道那做了什么。
该问题是由初始化程序中的某些代码引起的。您可以在错误日志中看到几行，其中显示“initializers/wicked_pdf.rb:38”。我为 wicked_pdf gem 重新生成了初始化程序，应用程序开始正常工作。我不知道为什么它不想在这台计算机上运行，因为它运行在另一台具有完全相同的操作系统和应用软件的计算机上。

【解决方案1】：

有同样的问题。
系统升级后，我的bundler版本是2.1.4，降级到2.0.2解决了这个问题。

【讨论】：

【解决方案2】：

这是由 bundler 2.1 中的重大更改引起的，您可以通过查看 Pull Request 了解更多信息。

此更改旨在防止您在调用 Gem.bin_path 时加载错误的可执行文件。假设 2 个 gem（myGem 和 yourGem）包含同名的可执行文件，run-my-program。调用Gem.bin_path("run-my-program") 不明确——您希望它加载哪个可执行文件？

这是一个重大的安全风险——您可能正在运行一个可执行文件，而认为您正在运行另一个。

为避免这种歧义，bundler 现在强制您在调用 Gem.bin_path 时指定要从哪个 gem 加载可执行文件：

Gem.bin_path(
  'myGem', # Ensures you load the executable from myGem instead of yourGem
  'the-executable-name'
)

检查你的源代码（你的堆栈跟踪建议一个很好的起点是config/initializers/wicked_pdf.rb）对于任何对Gem.bin_path、Gem.activate_bin_path或Gem.find_spec_for_exe的调用，并确保你传递了两个第二个参数：您要从中加载可执行文件的 gem，后跟可执行文件的名称。
