问题描述
我正在尝试重命名目标目录中的文件夹.我的 templates
文件夹中的目录结构如下所示:
I'm trying to rename a folder in the destination directory. The directory structure inside my templates
folder looks like this:
root/
├── generators
│ └── app
│ ├── templates
│ │ └── app
│ │ └── widget
│ │ ├── widget.controller.ts
│ │ ├── widget.service.ts
│ │ └── widget.module.ts
│ └── index.js
└── .yo-rc.json
我正在尝试将 widget
目录(在 destinationPath
中)重命名为用户在 prompting
阶段输入的名称.这是我尝试这样做的方式:
I'm trying to rename the widget
directory (in destinationPath
) to a name that the user enters during the prompting
stage. Here's how I'm attempting this:
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)
);
}
})
对 copyTpl
的调用正确地将应用程序从 templatePath
构建和模板化到 destinationPath
.但是,当调用 fs.move
操作时,我收到以下错误消息:
The call to copyTpl
is correctly scaffolding and templating the app from the templatePath
to the destinationPath
. However, when the fs.move
operation is called, I get the following error message:
PS C:\Users\username\code\generator-dashboard-widget-test> yo dashboard-widget

据我从 Yeoman 文件系统文档 中了解到,虚拟机上的所有操作文件系统是同步的,所以 app/widget
目录应该在 mem-fs-editor
实例尝试移动它之前存在.
From what I understand from the Yeoman file system documenation, all actions on the virtual file system are synchronous, so the app/widget
directory should exist before the mem-fs-editor
instance attempts to move it.
是否有不同的方式来重命名目录?
Is there a different way I should be renaming the directory?
我在带有节点 5.6.0 的 Windows 8.1 上使用 Yeoman 1.8.4.

推荐答案
我没有弄清楚这个具体问题,但我能够通过使用 gulp-rename
插件作为转换流:
I didn't figure out this specific issue, but I was able to accomplish what I was after by using the gulp-rename
plugin as a transform stream:
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);
},
我还打开了一个 GitHub 问题来跟进此行为:https://github.com/yeoman/yo/issues/455
I've also opened up a GitHub issue to follow up with this behavior here: https://github.com/yeoman/yo/issues/455
