小狗的外形特点描写内⽹环境怎么解决npm包的批量下载和往npm私有仓库批量上传
tgz依赖
背景：内⽹环境基于nexus搭建好了npm仓库，但是没有任何办法连接互联⽹。
微信网页登录轻车熟路的意思痛点：前端项⽬依赖多且碎，怎么解决npm包批量下载和上传到私有仓库的问题?
解决⽅案：
基于npm view及递归算法命令获取依赖包列表或基于--package-lock-only⽣成pack-lock.json⽂件从中读取依赖包列表
基于npm pack下载tgz格式的依赖
基于npm publish上传依赖到内⽹仓库或基于nexus api上传。
⼀、在互联⽹环境下载
1.1 基于npm view及递归算法命令获取依赖包列表或基于--package-lock-only⽣成pack-lock.json⽂件从中读取依赖包列表；
1.2 遍历上⼀步的依赖列表，基于npm pack命令，逐个下载。
参考代码如下：
const shell = require('shelljs');
const JSON5 = require('json5');
const { exec } = require('child_process');
function download(fileNames = []) {
shell.cd('download');
面试自我介绍简短let count = 0;
fileNames.forEach(fileName => {迷迷糊糊的拼音
// ho(`>>> 正在下载 ${fileName}...`);
const fileExec = (`npm pack ${fileName}`, { async: true, silent: true});
fileExec.stdout
.on('data', () => {
++count;
if (count === fileNames.length) {
shell.cd('..');
}
})
.on('err', () => {
++count
if (count === fileNames.length) {
shell.cd('..');
}
})
})
}

if (Array.isArray(deps)) {
