我正在尝试在GCP（Google云平台）上安装PCF（Pivotal Cloud Foundry）作为POC的一部分。
我一直在关注docs的指示。不幸的是，我遇到了一个路障，我的Elastic Runtime安装失败并出现以下错误。

我尝试在调试模式下运行此任务，据我所知，看起来syslog_forwarder是罪魁祸首。这是堆栈跟踪：

我已经浏览过互联网，但是，找不到任何有用的信息，因为我们还没有与Pivotal签订任何支持合同，他们的工程师将无法提供帮助。
如果有人能指出我正确的方向，我真的很感激。
我在发布此内容时正在下载1.11.7-build.5，并会在尝试后提供更新。
更新：与1.11.7-build.5完全相同的结果。
答案 0 :(得分：0)
显然，旧版本（确切地说1.10.21）提供了更好的错误消息。
事实证明，当您在Internal Databases - MySQL and Postgres中选择Pivotal Elastic Runtime -> Settings -> Databases选项时会发生此错误。
我将我的选择更改为Internal Databases - MySQL并修正了错误。
