ibmmq 节点客户端找不到 MQ C 库，始终失败

Question

我正在尝试创建一个对服务器和 MQ 容器进行 docker 化的节点应用程序，并使用 ibmmq 节点客户端与所述容器进行交互。 我遇到了一个问题，我无法让我的服务器运行，因为找不到 MQ C 库。 有问题的具体错误：

Cannot find MQ C library.
   System appears to be: linux[x64]
   Has the MQ C client been installed?
   Have you run setmqenv?
 Error: ENOENT: no such file or directory, open '/opt/mqm/lib/libmqm_r.so'
     at Object.openSync (fs.js:462:3)
     at readFileSync (fs.js:364:35)

 [ERROR] 07:40:21 Error: ENOENT: no such file or directory, open '/opt/mqm/lib/libmqm_r.so'

当我 go 检查 /opt/... 时，没有文件夹 mqm。 我不太确定何时会在此过程中创建它。

这是我的 docker 文件：

FROM node:12

# Non-development values will be provided by Drone when
# deploying to staging or production
ARG ENV="development"

WORKDIR /server

COPY package.json .
COPY yarn.lock .

RUN yarn install --production=false

COPY . .

# In non-dev environments, we need to build executable code
# during image build time so that we're not doing it at
# container startup (which would cause significant down-time)
RUN if [ $ENV = "staging" ] || [ $ENV = "production" ]; \
  then yarn build;  \
  fi

CMD ["yarn", "serve"]

触发问题的具体代码：

import mq from 'ibmmq'

const MQC = mq.MQC

我尝试了一些方法，包括不让 c 库构建，但没有任何效果。 任何帮助将不胜感激，在此先感谢！

请参阅https://github.com/ibm-messaging/mq-mqi-nodejs/tree/master/samples以了解使用npm install的工作 Dockerfile 示例。

linux x64 的安装后脚本通常会引入 MQ Redist C 客户端 package。如果安装后由于某种原因未运行，或者无法下载 package，则必须手动安装 MQ C 客户端。
