cnpminstall报错：Connecttimeoutfor5000ms踩坑

这次发布项目自动化打包，cnpm install 报错，报错如下

Get /binary-mirror-config/latest from https://registry.npm.taobao.org error: ConnectionTimeoutError: Connect timeout for 5000ms, GET https://registry.npmjs.com/binary-mirror-config/latest -2 (connected: false, keepalive socket: false, agent status: {"createSocketCount":4,"createSocketErrorCount":0,"closeSocketCount":4,"errorSocketCount":0,"timeoutSocketCount":0,"requestCount":0,"freeSockets":{},"sockets":{},"requests":{}}, socketHandledRequests: 1, socketHandledResponses: 0)……

执行命令

time curl -v https://registry.npm.taobao.org/binary-mirror-config/latest
测试网络

{"latest":"1.20.0"}}
real    0m10.716s
user    0m0.054s
sys 0m0.084s

然后找到报错根源：/nodejs/lib/node_modules/cnpm/node_modules/urllib/lib/urllib.js

修改掉文件里面的常量 TIMEOUT、TIMEOUTS 的 5s 为 10s

然后&……

大功告成！

# npm 不能下载的时候这样做
rm  package-lock.json
rm -rf node_modules
npm cache clear --force
