调用 /render 时石墨错误“'ParseResults' 对象没有属性 'raw'”

Question

我用 pip 方法安装了 graphite ( whisper - carbon - graphite-web )。

我将它连接到我的 puppetserver 实例（需要 graphite 来获取 jrubies 信息）。

但是当我尝试将数据从 Graphite 导出到我的 grafana 时出现错误：AttributeError: ParseResults object has no attribute raw 当我添加数据源时。

在 graphite-web 日志文件中我有：

有没有人可以帮助我理解为什么会出现此错误以及如何解决？提前致谢

+1 今天在新的 Graphite 安装上遇到了完全相同的错误......否则探索指标和检索数据似乎工作正常。

更新：重新安装 pyparsing 版本 2.4.7（我在另一个工作环境中使用的版本）而不是 3.0.4（出现错误的版本）似乎可以解决问题。

Answer 2

我今天也遇到了。 Graphite 可以很好地显示标准数据，但我无法运行任何针对数据的函数（averageSeries、sumSeries 等）。这些请求都会在浏览器中导致错误 500，并具有您在上面发布的相同堆栈。 pyparsing==3.0.4 的 release notes 将此描述为预期行为：

result = Word(alphas).parseString("abc") result.xyz = 100

now raises this Python exception:

AttributeError: 'ParseResults' object has no attribute 'xyz'

To add new attribute values to ParseResults object in 3.0.0 and later, you must assign them using indexed notation:

result["xyz"] = 100

如果您检查堆栈中引用的行（grammar_unsafe.py 第 83 行），您会发现 Graphite 确实试图在不使用索引符号的情况下分配 'raw' 属性。我试图用不同的结果编辑这一行。一些图表会呈现，但 apache 重启还有其他问题，因此简单地更新设置 toks[0].raw 中使用的符号只会使问题复杂化。我已经记录了 graphite-web 的问题，在此期间，按照推荐答案中的建议将我的 pyparsing 降级为 2.4.7。
