使用Yeoman(mem-fs编辑器)重命名新创建的目录

yeoman-generator yeoman

Nathan Friend · 技术社区 · 9 年前

我正在尝试重命名目标目录中的文件夹。我的 templates 文件夹如下所示:

root/
âââ generators
â   âââ app
â       âââ templates
â       â   âââ app
â       â       âââ widget
â       â           âââ widget.controller.ts
â       â           âââ widget.service.ts
â       â           âââ widget.module.ts
â       âââ index.js
âââ .yo-rc.json

我正在尝试重命名 widget 目录(在 destinationPath )到用户在 prompting 阶段我是这样尝试的:

module.exports = generators.Base.extend({
    copyAppTemplate: function () {
        this.fs.copyTpl(this.templatePath('**/*'), this.destinationPath('.'), this.props);

        this.fs.move(
            this.destinationPath('app/widget'),
            this.destinationPath('app/' + this.props.widgetName)
        );
    }
})

呼叫 copyTpl 正确地从 templatePath 到 目标路径 然而,当 fs.move 调用操作时,我收到以下错误消息:

PS C:\Users\username\code\generator-dashboard-widget-test> yo dashboard-widget
? Your widget's name: (generator-dashboard-widget-test)
? Your widget's name: generator-dashboard-widget-test

events.js:154
    throw er; // Unhandled 'error' event
    ^

据我所知 Yeoman file system documenation ,虚拟文件系统上的所有操作都是同步的,因此 app/widget 目录应在 mem-fs-editor 实例尝试移动它。

有没有其他方法可以重命名目录?

我在Windows 8.1上使用Yeoman 1.8.4,节点为5.6.0。

我没有发现这个具体问题,但我能够通过使用 gulp-rename 作为转换流的插件:

copyAppTemplate: function () {
    var _this = this;

    // move a file like "app/widget/widget.controller.ts" to 
    // "app/my-widget-name/my-widget-name.controller.ts"
    this.registerTransformStream(rename(function (path) {
        path.dirname = path.dirname.replace('widget', _this.props.widgetName);
        path.basename = path.basename.replace('widget', _this.props.widgetName);
        return path;
    }));

    this.fs.copyTpl(this.templatePath('**/*'), this.destinationPath('.'), this.props);
},

我还发现了一个GitHub问题,以在此处跟踪此行为: https://github.com/yeoman/yo/issues/455
