puppet - 调用fail()失败

Question

我正在尝试设置一个新的 puppetmaster (v5.0.1)，一切都很顺利，除了一件事。

我无法调用fail()在我的 list 中。当它尝试运行任何fail()时函数，它会抛出一个评估错误。

这种情况发生在 list 中，并且也适用于 puppet 应用。

$ puppet apply -e 'fail("Failure")' --trace

将返回以下错误和跟踪:

我确定是我的问题，但我不知道是什么原因造成的。

Answer 1

fail() 函数按设计工作，但错误消息令人困惑。

fail() 函数只是 raise Puppet::ParseError 的包装。通常，当 Puppet 函数没有执行其应该执行的操作时，会引发 Puppet::ParseError 。在这种情况下，消息评估函数调用时出错是有意义的。

但是，这里会引发错误，因为该函数正在执行它应该做的事情 - 为您引发错误。因此，这不是“评估函数调用时的错误”。

但一直都是这样。
