在本地启动 rails 服务器时出错 - Puma - runner.rb:103:in `reopen'- 没有这样的文件或目录 @ rb_io_reopen

Question

我在尝试在本地启动 rails 服务器时遇到以下错误。生产环境中的存储库工作正常。生产中的最新版本被克隆到本地。唯一的变化是 gemfile 中的 rails 版本；从 ruby '2.2.1' 更改为 ruby '2.2.3'。捆绑包更新后，在尝试启动 rails 服务器时会显示此 problem/error。

I am using a mac, the users directory is Users/circle. (issue could be related to puma version, rvm version and gem file versions). But any hints and suggestions in this regards would be greatly appreciated. 

[3951] Puma starting in cluster mode...

Answer 1

错误的第一行说

No such file or directory @ rb_io_reopen - /Users/circle/Test_new/testdirectory/shared/log/puma.stdout.log (Errno::ENOENT)

所以我认为您应该手动创建该文件，看看是否能解决您的问题。在托管平台上，幕后可能有一个初始化脚本会像这样进行设置。

Answer 2

将生产环境中的gemfile.lock替换到本地仓库中确实解决了问题。 Post 我已经能够在本地主机上启动 rails 服务器和运行。

这实际上意味着，对于某些文件，需要完全相同版本的相关库，而不仅仅是来自 gem 文件和捆绑包更新的最新版本。因为，Gemfile.lock 是 Git 忽略的文件之一。因此，它在克隆时没有在本地更新。它必须以独占方式获取并在本地存储库中替换。捆绑包更新，post，有东西运行。
