What can I do to fix this?

推荐答案

解决了一个小时一样，最终得出结论:
1.我的全局和本地 CLI 不匹配(1.6.4 g vs 1.6.3 l)，所以我跑了 npm install --save-dev @angular/cli@latest
2.之后是另一个警告:
错误:多个模块匹配.使用跳过导入选项跳过将组件导入最近的模块.不止一个模块匹配.使用跳过导入选项跳过将组件导入最近的模块.",
so ng g c my-component --skip-import 现在按预期工作.
我希望它会有所帮助.

for an hour was solving the same, eventually concluded:
1. My global and local CLI mismatched (1.6.4 g vs 1.6.3 l), so I ran npm install --save-dev @angular/cli@latest
2. After that that was another warning:
"Error: More than one module matches. Use skip-import option to skip importing the component into the closest module. More than one module matches. Use skip-import option to skip importing the component into the closest module.",
so ng g c my-component --skip-import now works as expected.
I hope it will help.
