CI/CD的node.js编译报错npm ERR! network request to https://registry.npmjs.org/

1、背景：

在维护paas云平台过程中，有研发反馈paas云平台上的CI/CD的前端流水线执行异常。

2、问题描述：

流水线执行的是前端编译，使用的是node.js环境。报错内容如下：

npm install

npm run build:test

result=$? #结果返回值

if $$result -ne 0$ ; then

exit 1 #异常退出容器

fi

cp -r ./dist /app/pkg

cp nginx.conf /app/pkg

3、问题分析：

1、通过查看流水线执行的日志内容，npm ERR! network request to https://registry.npmjs.org/@vue%2Fcli-plugin-router failed

2、初步分析是容器访问https://registry.npmjs.org地址有问题，需要在宿主机上执行telnet命令验证一下。
bash 复制代码
# ping registry.npmjs.org
PING registry.npmjs.org (104.16.0.35) 56(84) bytes of data.
64 bytes from 104.16.0.35 (104.16.0.35): icmp_seq=1 ttl=52 time=134 ms

[2]+  已停止               ping registry.npmjs.org


# telnet registry.npmjs.org 443
Trying 104.16.0.35...
Connected to registry.npmjs.org.
Escape character is '^]'.

通过上面的网络检查手段，可以确认网络是通的。
3、再次查看node.js编译脚本的config配置是https://registry.npmmirror.com镜像地址。

4、所以得出结论是执行中使用的npm镜像地址和实际脚本配置的npm config地址对不上，导致报错了。

因为代码里的要求是使用淘宝的npm镜像地址的。
所以需要设置默认的npm镜像地址。

bash 复制代码

npm config set registry https://registry.npmmirror.com

4、问题解决：

node.js编译脚本中配置npm的默认镜像地址。设置后的node.js脚本配置内容如下：
#!/bin/sh

CMD 脚本执行的工作目录为 pipeline 基础镜像的文件系统目录，包含 clone 的代码

rm -rf /app/pkg/*
npm config set registry https://registry.npmmirror.com/

npm install

npm run build:test

result=$? #结果返回值

if $$result -ne 0$ ; then

exit 1 #异常退出容器

fi

cp -r ./dist /app/pkg

cp nginx.conf /app/pkg
再次执行CI/CD的流水线编译过程，最后执行成功了。

5、总结：

如果node.js在使用npm时，默认的镜像地址为：https://registry.npmjs.org/，但是这个地址是外国地址，基本是不通的，同时国内开发前端程序时，基本默认配置的淘宝的地址。

因此，大家在遇到这个错误时，可以参考如上的分析过程。
