npm - 如何在我的 package.json 中使用单个 github 文件作为依赖项？

Question

我有一个旧项目使用这个 project它基本上只是一个 JS 文件。我试过用几种方法添加它...

"jquery-highlight-regex": "jbr/jQuery.highlightRegex"

npm ERR! eisdir EISDIR: illegal operation on a directory, read
npm ERR! eisdir This is most likely not a problem with npm itself
npm ERR! eisdir and is related to npm not being able to find a package.json in
npm ERR! eisdir a package you are trying to install.

"jquery-highlight-regex": "https://raw.githubusercontent.com/jbr/jQuery.highlightRegex/master/highlightRegex.js"
npm ERR! not a package /var/folders/vf/mnj9dq116gvcww95cbk3r3n40000gp/T/npm-32798-d819bc7b/raw.githubusercontent.com/jbr/jQuery.highlightRegex/master/highlightRegex.js
npm ERR! Darwin 16.0.0
npm ERR! argv "/Users/.../bin/node" "/Users/.../apps/node/bin/npm" "install"

那么如何在没有 package.json 的情况下包含一个简单的 JS 文件作为依赖项？

Answer 1

您可以使用安装后脚本以及依赖项，例如 download-cli手动拉取文件。如果文件经常更改，这可能很有用，例如 mjaggard 的情况。

以下示例 package.json 将在安装时获取文件并将其放置在 /third-party 文件夹中。

{
  "name": "so-npm-download-on-install",
  "version": "1.0.0",
  "scripts": {
    "postinstall": "download --out third-party https://raw.githubusercontent.com/jbr/jQuery.highlightRegex/master/highlightRegex.js"
  },
  "dependencies": {
    "download-cli": "^1.1.1"
  }
}
