Ruby on rails 没有这样的文件或目录-/dev/null（Errno:：enoint）

我这里有一个和这位先生相似的人

我一直在尝试通过rake任务运行cucumber特性。我在标题中发现了指定的错误

这是一个完整的回溯。还有我的ruby版本。（当我试图运行rails版本命令时，我得到了“commandnotfound”

---

任何帮助都将不胜感激。谢谢。

我真的找到了答案。我正在处理的应用程序中有一个配置设置，位于一个稍微模糊的文件中。它将记录器的路径设置为“/dev/null”。我只是将其改为“logger.txt”现在它可以工作了。

这个

dev/null

在

config/initializers/quiet\u assets

中，我用

logger.txt

替换了

dev/null

，如果你在*nix和windows上使用相同的应用程序，你可以替换

'/dev/null'

使用RUBY_平台！=“i386-mingw32”？“/dev/null”：“NUL”

对我来说，它在安静的_assets.rb中，我替换了它

Rails.application.assets.logger=logger.new（'/dev/null'）

与

---

Rails.application.assets.logger=logger.new（RUBY_PLATFORM！=“i386-mingw32”？“/dev/null”：“NUL”）

查看另一个问题的答案和注释。具体来说，您的代码（或配置）中是否配置了记录器某个地方？我不知道，我也不完全确定如何实际配置它。其他评论部分建议这样做，但我不是100%确定如何做。否则我会全力支持。建议？尝试在您的存储库中搜索

/dev/null

（例如

git grep/dev/null/

，如果您使用的是git）。我确实找到了答案。我正在处理的应用程序中的一个稍微模糊的文件中有一个配置设置。它将记录器的路径设置为“/dev/null”。我刚刚将其更改为“logger.txt”，它现在可以工作了。感谢帮助！：）看到了吗？容易的。如果我可以使用webmachine ruby的一个例子，并且这个补丁适合我，我会+2这个。
