node.js - 在企业环境中创建 Angular 项目（无 Internet）

问题描述

我在一个必须代理（或隔离）所有东西的公司环境中工作。我们有 Artifactory Pro 来镜像 Maven Central、NPM Registry 和 DockerHub。我们多年来一直在使用 Maven，它的效果非常好。我们最近开始通过 Node.js 和 npm 使用 Angular 进行前端开发。安全要求保持不变。

当使用 Angular CLI () 创建一个新的 Angular 项目时ng new my-app，会从我们公司的 Artifactory 实例中获取数百个 npm 依赖项，这是预期的。但是，该过程在几分钟后失败，并显示以下消息：

[...]

额外细节

Bottom line is:我希望从头到尾ng new浏览我们的 Artifactory，而不是从互联网上获取东西。错误日志提到设置代理，但该 URL 在我们的公司环境中被阻止。

有什么想法吗？

解决方案

我看到了问题。node-sass安装脚本是硬编码的，可以从github.

$ npm i --verbose node-sass
   ...
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.11.0/darwin-x64-64_binding.node

在检查了它试图运行的脚本 ( node_modules/node-sass/scripts/install.js) 之后，我确定可以跳过这个额外的下载。它将要求机器在本地构建它（一次，在初始安装时），但它应该会有所帮助。

$ SKIP_SASS_BINARY_DOWNLOAD_FOR_CI=true npm i --verbose node-sass

旧答案

您可以对您的.npmrc文件执行此操作。如果您希望它应用于您的所有项目（听起来您想要这个），请将其放在您的用户主目录中。

registry=<your registry url>
always-auth=true
_auth=<your auth string>
