"Cannot find module" 在 browserify 中不破坏包时

Question

我有一个自定义库，正在尝试使用 Browserify 构建。该库使用 fabric.js，使用一些自定义类对其进行扩展，并将其全局公开以在浏览器和 node.js 中使用。这是库的主要入口点：

(function () {
    "use strict";

    // Make fabric global in browsers and node
    this.fabric = require('./libs/fabric.canvasex.js');
    this.fabric.internal_version = "1.0.0";

    require('./libs/BoundedText/BoundedText.js');
    require('./libs/BoundedText/PathText/PathIText.js');
    require('./libs/VectorPlaceholder/fabricVectorPlaceholder.js');
    require('./libs/ImagePlaceholder/fabricImagePlaceholder.js');

}).call(this);

这个库的文件结构是这样的：

要将此库构建为单个文件，我正在使用此命令：

browserify --full-paths js/main.js | uglifyjs --compress --mangle safari10 > dist/my-lib.js

这很好用，我可以将其包含在浏览器中并在 node.js 中要求它，它也成为一个全局变量，这正是我所需要的。当我必须调试某些东西时，问题就开始了，而缩小的代码显然不适合这个，所以我像这样捆绑库：

browserify --full-paths js/main.js > dist/my-lib.js

现在，当我尝试使用 browserify 将此构建包含在另一个节点程序中时，如下所示：

require('./customily-fabric.js');

我在将我的程序与库捆绑在一起时遇到这些错误：

[1] Error: Cannot find module '../fabric.js' from 'D:\Git-Repos\Customily\CustomilyFabric\dist'
[1] Error: Cannot find module './OpentypeIText.js' from 'D:\Git-Repos\Customily\CustomilyFabric\dist'

[1] Error: Cannot find module './libs/fabric.canvasex.js' from 'D:\Git-Repos\Customily\CustomilyFabric\dist'

我发现，如果我只从我的库构建中删除 --mangle 选项，我会在尝试将其包含在另一个节点程序中时遇到这些错误。为什么会这样？不应该所有模块都包含在包中吗？

经过一番查找，终于找到原因，使用browserify时无法添加与browserify捆绑的库，参见this问题。

此功能将在 browserify 17 中推出，所以现在，我切换到 webpack 来构建我的库。

"Cannot find module" 在 browserify 中不破坏包时

"Cannot find module" in browserify when not mangling the bundle

javascript

node.js

node-modules

browserify

uglifyjs
