如果我有应用程序的源代码和 macOS 和 Windows 安装程序，我如何才能找到用于构建应用程序的 Node.js 版本？

Question

我需要构建一个新版本的 javascript Node.js应用程序。 我有该应用程序先前版本的源代码以及 macOS 和 Windows 安装程序。

我怎样才能找到Node.js的哪个版本用于构建以前版本的应用程序，以便我可以使用相同的Node.js版本来构建我的新版本的应用程序？

我知道在构建 macOS 版本和 Windows 版本时， Node.js的版本可能不同。 理想情况下，我想知道每个平台使用的是哪个版本的Node.js ，但如果我能得到至少一个就足以满足我的需要的话。

更新：package.json：

Answer 1

Node.js 不与应用程序的源代码捆绑在一起。 package.json可能有一个名为"engines"的部分，其中将 state 您应该使用什么版本。

如果根package.json没有"engines"部分，那么某些依赖项可能会说明它们需要使用哪个版本。 逐个检查会有点烦人，所以一个好方法就是下载一个版本的 Node 并运行npm install 。 如果一切正常，那么您知道创建应用程序的 Node 版本很可能较旧（我知道这有点乏味）。

您可以寻找的另一件事（但可能没有帮助）是检查源代码文件的创建时间（尤其是package.json文件），并找到当时发布的 Node 版本。 这不会像第一种方法那样准确，但它会给你一个 Node.js 的工作版本。

但是，归根结底，最好使用最新版本（或最新的 LTS 版本），因为它们带有所有最新的安全补丁和改进。
