呼叫失败（）失败

Question

我正在尝试设置一个新的puppetmaster（v5.0.1）并且一切顺利，除了一件事。

我无法在我的清单中致电fail()。当它尝试运行任何fail()函数时，会抛出评估错误。

这种情况发生在清单中，并且木偶也适用。

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

将返回以下错误和跟踪：

我确定是我，但我无法弄清楚是什么导致了这一点。

Answer 1

fail()函数按设计工作，但错误信息令人困惑。

fail()函数只是raise Puppet::ParseError的包装。通常情况下，当Puppet函数不执行它应该执行的操作时，会引发Puppet::ParseError。在这种情况下，消息Error while evaluating a Function Call是有道理的。

然而，这里出现错误，因为函数正在执行 应该做的事情 - 为您引发错误。因此，在评估函数调用时，这不是一个错误＆＃34;。

虽然一直都是这样。
