ibmmq 節點客戶端找不到 MQ C 庫，始終失敗

Question

我正在嘗試創建一個對服務器和 MQ 容器進行 docker 化的節點應用程序，並使用 ibmmq 節點客戶端與所述容器進行交互。 我遇到了一個問題，我無法讓我的服務器運行，因為找不到 MQ C 庫。 有問題的具體錯誤：

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)

當我 go 檢查 /opt/... 時，沒有文件夾 mqm。 我不太確定何時會在此過程中創建它。

這是我的 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"]

觸發問題的具體代碼：

import mq from 'ibmmq'

const MQC = mq.MQC

我嘗試了一些方法，包括不讓 c 庫構建，但沒有任何效果。 任何幫助將不勝感激，在此先感謝！

請參閱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 的安裝后腳本通常會引入 MQ Redist C 客戶端 package。如果安裝后由於某種原因未運行，或者無法下載 package，則必須手動安裝 MQ C 客戶端。
