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:

node.js编译的脚本配置如下:
#!/bin/shCMD 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 https://registry.npmmirror.com/
npm install
npm run build:test
result=$? #结果返回值
if [ $result -ne 0 ]; then
exit 1 #异常退出容器
fi
cp -r ./dist /app/pkg
cp nginx.conf /app/pkg
3、问题分析:
1、通过查看流水线执行的日志内容,npm ERR! network request to https://registry.npmjs.org/@vue%2Fcli-plugin-router failed
2、初步分析是容器访问https://registry.npmjs.org地址有问题,需要在宿主机上执行telnet命令验证一下。
bash# ping registry.npmjs.org PING registry.npmjs.org (104.16.0.35) 56(84) bytes of data. 64 bytes from 104.16.0.35 (104.16.0.35): icmp_seq=1 ttl=52 time=134 ms 64 bytes from 104.16.0.35 (104.16.0.35): icmp_seq=2 ttl=52 time=134 ms 64 bytes from 104.16.0.35 (104.16.0.35): icmp_seq=3 ttl=52 time=135 ms ^Z [2]+ 已停止 ping registry.npmjs.org # telnet registry.npmjs.org 443 Trying 104.16.0.35... Connected to registry.npmjs.org. Escape character is '^]'.
通过上面的网络检查手段,可以确认网络是通的。
3、再次查看node.js编译脚本的config配置是https://registry.npmmirror.com镜像地址。4、所以得出结论是执行中使用的npm镜像地址和实际脚本配置的npm config地址对不上,导致报错了。
因为代码里的要求是使用淘宝的npm镜像地址的。
所以需要设置默认的npm镜像地址。
bash
npm config set registry https://registry.npmmirror.com
4、问题解决:
node.js编译脚本中配置npm的默认镜像地址。设置后的node.js脚本配置内容如下:
#!/bin/shCMD 脚本执行的工作目录为 pipeline 基础镜像的文件系统目录,包含 clone 的代码
rm -rf /app/pkg/*
npm config set registry https://registry.npmmirror.com/npm install
npm run build:test
result=$? #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。
