尝试在 Splunk 上安装 gRPC python 模块

Question

我正尝试在 Splunk 上运行外部 python 脚本 "PyClient.py"，它需要外部 gRPC 模块。我按照 http://www.grpc.io/docs/quickstart/python.html 的快速入门 python 指南在本地安装了 gRPC 模块。 splunkd文件中产生的日志如下：

有人对如何清除此错误有任何建议吗？或者如何在Splunk上安装外部gRPC模块？

提前致谢。

Answer 1

这看起来像是 32/64 位 Windows 不兼容。

安装 gRPC 时，请确保您明确使用 Python 到 pip install grpcio 的 Splunk 分布。

C:\Program Files\Splunk\<Python2.7 binary> -m pip install --upgrade pip

C:\Program Files\Splunk\<Python2.7 binary> -m pip install grpcio

Answer 2

我已经找到了解决方案。我必须为我的 python 脚本编写一个包装脚本，该脚本取消设置或删除 (del) "LD_LIBRARY_PATH" 和 "PYTHONPATH"。对于基于 Linux 的系统，我还必须取消设置或删除 (del) "PATH" 环境变量。按照上述步骤后，Splunk 使用了我本地版本的 Python 和安装的模块。它奏效了。希望这可以帮助任何试图在 Splunk 中使用外部模块但似乎无法弄清楚为什么它不起作用的人。 :)
