Python 3.x 提交时发生MQRC_环境_错误

尝试使用pymqi向IBM MQ发送消息时遇到问题。 我正在做的一个项目

• 从DB2读取数据
• 为

  WorkerProcess

• WorkerProcess

  基于该数据执行一些决策，并向MQ发送消息

当

WorkerProcess

尝试提交MQ的消息时，我收到一个错误：

Stacktrace:
    worker_process.py:
        self.mq.commit()
    mq_service.py:
        self.qmgr.commit()
    pymqi/__init__.py line 1689, in commit
        raise MQMIError (rv[0], rv[1])
pymqi.MQMIError: MQI Error. Comp: 2, Reason 2012: FAILED: MQRC_ENVIRONMENT_ERROR

代码和堆栈跟踪是手工输入的，可能包含打字错误

下面的代码是我正在做的事情的伪代码

非常感谢您的帮助和/或建议

编辑： 其他信息：

• 我正在运行IBMMQ客户端版本9.1.0.1

• AMQERR0*.LOG

  文件中没有错误

• 已设置LD_库_路径

• 重构代码时显示此错误

下面是正在运行的代码（重构前）：

为了简洁易读，函数签名中的一些参数被（args）替换*

您是否安装了mq客户端库？检查文件

AMQERR01.LOG

并查看错误。还要确保您的库路径包括MQ安装库（32位）或lib64（64位）。感谢您的帮助@JoshMc；我忘了提到这个错误发生在代码重构之后。我已经编辑了我的问题并添加了以前的代码/var/mqm/errors/AMQERR01.log为空。添加

connect\u options=pymqi.CMQC.MQCNO\u HANDLE\u SHARE\u块的建议是什么？这被记录为“应用程序和本地队列管理器代理是同一执行单元的一部分”。错误描述说明“应用程序链接到错误的库（线程或非线程）。”pymqi是否编译为支持多线程？您好，如果我不使用此选项，我将连接MQRC_。我在pymqi中找到了这个解决方案
