Ruby on rails Rspec-guard可以防止任何语法错误（使用spork）

使用spork在guard内运行rspec--drb时出现问题： 在ruby文件（项目或规范文件）中出现任何语法错误后，运行rspec命令和跟踪更改看起来就像是警卫停止一样

当我在没有spork（也没有--drb）的情况下从guard运行rspec时，它工作得很好。 此外，spork+rspec工作正常，然后在没有防护装置的情况下运行

错误：

就个人而言，我建议从spork切换到or

但这与这里的问题无关

首先，最好在guard rspec的GitHub页面上打开问题。（您可能会得到更快的响应，并且可以跟踪何时正式发布修复程序）

问题就在这里：

18:18:22 - ERROR - Guard::RSpec failed to achieve its <run_all>, exception was:
> [#ede981094807] Errno::ENOENT: No such file or directory @ rb_sysopen - tmp/rspec_guard_result

18:18:22-错误-Guard:：RSpec未能实现其目标，异常为：
>[#ede981094807]Errno:：enoint:没有这样的文件或目录@rb_sysopen-tmp/rspec_guard_result

由于某种原因，

guard rspec

无法打开其结果文件

我猜这是因为当您使用

--drb

运行rspec时，故障不会报告给Guard rspec（通过

Guard:：RSpecFormatter

类）

所以我不确定rspec--drb是否可以在这里工作。您可以尝试更新版本的RSpec，看看它是否有帮助

如果你能建立一个小型回购，重现问题，并在中打开一个问题，我可以看看
