呼叫失敗（）失敗

Question

我試圖設置一個新的puppetmaster（v5.0.1），並且一切順利，除了一件事。

我無法在我的清單中調用fail()。當它試圖運行任何fail()函數時，它會拋出一個評估錯誤。

這種情況發生在清單中，並且也適用於傀儡。

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

將返回以下錯誤和跟蹤：

我敢肯定，這是我，但我想不出是什麼原因導致這一點。

Answer 1

fail()函數按設計工作，但錯誤信息令人困惑。

fail()函數僅僅是圍繞raise Puppet::ParseError的一個包裝。通常，Puppet::ParseError是在Puppet函數而不是做它應該做的事情時引發的。在這種情況下，消息Error while evaluating a Function Call是有道理的。

但是，在這裏提出錯誤是因爲該函數正在執行的操作完全是是應該做的 - 爲您產生錯誤。所以，這不是評估函數調用時的「錯誤」。

它一直是這樣的。
