默认情况下不启用基于网络的加载

【Network-based loading is not enabled by default】

目前，需要使用 --experimental-network-imports 标志来启用通过 http: 或 https: 加载资源。将来，将使用不同的机制来强制执行这一点。需要选择加入，以防止传递性依赖意外使用可能影响 Node.js 应用可靠性的可变状态。

【For now, the --experimental-network-imports flag is required to enable loading resources over http: or https:. In the future, a different mechanism will be used to enforce this. Opt-in is required to prevent transitive dependencies inadvertently using potentially mutable state that could affect reliability of Node.js applications.】
