Npm 离线 package 安装在 docker 容器

Question

我正在尝试将 node-red-contrib-influxdb 安装在无法访问 inte.net 的计算机上的 node-red docker 容器中。 我有一台 Windows 计算机，我还安装了 node.js，并安装/下载了 node-red-contrib-influxdb package 和 npm-pack-all。

我尝试在 node-red-contrib-influxdb 安装位置运行 npm-pack-all 以安装所有依赖项（我也手动安装了那些依赖项，但这没有帮助）并将生成的 tgz 文件移动到docker 容器并在其上运行 npm 安装。 这会导致以下错误：

npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN
npm ERR! request to https://registry.npmjs.org/influx failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org

npm ERR! A complete log of this run can be found in:
npm ERR!     /usr/src/node-red/.npm/_logs/2023-01-31T14_33_13_404Z-debug.log

日志中的相关行是：

我将如何解决此错误并启用此特定 npm package 的离线安装？

Answer 1

我会以不同的方式处理这个问题。

通过扩展现有容器创建自定义 Node-RED 容器，然后在构建容器时安装所需的节点（在具有 inte.net 访问权限的机器上），然后将新容器复制到离线机器。

例如

FROM nodered/node-red:latest
USER root
RUN npm install node-red-contrib-influxdb
USER node-red

USER 开关是因为安装将进入 Node-RED 旁边的/usr/src/node-red
