如何从生成器存储库 运行 全局生成生成器？
How to run a global generate generator from a generator repository?
说我们在存储库中 generate-mygenerator。
因此我们在根目录中有一个 generator.js 文件。
如果我想 运行 gen gh-repo 怎么办？
我收到以下错误：

我是否必须将 generator.js 重命名为 generator.js.wait，然后在生成器完成后将其重命名？
重现错误的步骤：

原则
只要 generate-gh-repo 已全局安装并且您的 generator.js 文件中没有名为 gh-repo 的任务，全局生成器应该 运行。
如果您的 generator.js 文件中有一个任务与您尝试 运行 的全局安装的生成器同名，那么该任务将 运行 代替。这是因为生成器将以比全局生成器更高的优先级解决任务。
您可以通过 运行ning gen gh-repo:default 将全局生成器 运行 （将 gh-repo 替换为您尝试 运行).这告诉生成器在 gh-repo 生成器上寻找默认任务。如果您没有像这样在 generator.js 文件中注册 gh-repo 生成器：
app.register('gh-repo', require('generate-gh-repo'));
然后生成应该找到全局安装的生成器。
它应该有效
当你 运行 gen gh-repo.
它应该可以正常工作
为避免此错误，只需安装本地 npm 依赖项
我只是重现了错误的行为，只是试图 运行 另一个尚未安装本地节点模块的生成器的根文件夹中的全局生成器！
