npm安装报错： errno ETIMEDOUT network request toXXX failed, reason: connect ETIMEDOUT

• 前端 
npm install --save html2canvas

今天执行这段安装报错：

npm WARN using –force I sure hope you know what you are doing.

npm ERR! errno ETIMEDOUT

npm ERR! network request to http://registry.npmjs.org/html2canvas failed, reason: connect ETIMEDOUT 104.16.17.35:80

npm ERR! network This is a problem related to network connectivity.

npm ERR! network In most cases you are behind a proxy or have bad network settings.

npm ERR! network

npm ERR! network If you are behind a proxy, please make sure that the

npm ERR! network ‘proxy’ config is set properly.  See: ‘npm help config’

npm ERR! A complete log of this run can be found in:

npm ERR!     D:\nodejs\node_cache\_logs\2022-11-18T01_42_13_930Z-debug.log

1、查询下网络代理：

npm config get proxy

==》false

npm config get npm config get https-proxy

==>undefined

npm config get registry

==》http://registry.npmjs.org/

2、重新设置代理

 npm config set proxy false

 npm cache clean –force

npm config set registry https://registry.npmjs.org

3、安装成功

4、如果用官方源也不能连接的话，试试淘宝源（推荐）

$ npm config set registry http://registry.npm.taobao.org/
