Angular2 - 找不到 NgModule [英] Angular2 - Could not find an NgModule
问题描述
您好，我刚刚使用简单的
Hello I've just created a new project from the CLI using the simple
ng new frontend
然而，一旦我进入我的项目，命令:
command however once I go into my project to:
cd frontend/src/app
并尝试像这样生成一个新组件
and try to generate a new component like so
ng generate component about
我在我的终端 (MacOS) 中收到以下错误消息:找不到 NgModule.在 NgModule 中使用跳过导入选项跳过导入.
I get the following error message in my terminal(MacOS): Could not find an NgModule. Use the skip-import option to skip importing in NgModule.
我已经全局安装了 Angular 2，并且当我运行我的
I have installed Angular 2 globally and when I run my
ng --version
我收到以下信息:
Angular CLI: 6.0.0
Node: 8.11.1
OS: darwin x64

我的尝试:我试过重新安装 Angular.我已经确认我的 TypeScript 是最新的.我的 NPM 是最新的等等.我按照 Angular.io 提供的教程的最基本步骤创建了一个新项目，但无济于事.
What I've tried:
I have tried reinstalling Angular. I have confirmed my TypeScript is up to date. my NPM is up to date and so on. I've created a new project following the most basic steps of the tutorial provided at Angular.io to no avail.
如果有人能告诉我这里出了什么问题，我将不胜感激.
If anyone can lecture me on what is going wrong here I'd greatly appreciate it.
在起草这篇文章时，我有一个绝妙的想法，即通过我的 IDE 终端运行这个过程，令人震惊的是 ng generate component about 工作没有问题.然而，出于好奇并想知道我的本地终端出了什么问题，我想我终究会发帖.
While drafting this post I had the brilliant idea of running this process through my IDE's terminal and shockingly ng generate component about worked without a problem. However being curious and wanting to know what is wrong with my native terminal I figured I'd post after all.
编辑 2:如此随意的想法突然出现在我的脑海中，简单明了的文件权限......是的使用 sudo ng g c about 工作.所以你有它我想.希望这对那里的人有所帮助.
EDIT 2:
So random thought popped in my head plain and simple File Permissions...yup
using sudo ng g c about worked. So there you have it I suppose. Hopefully this was helpful to someone out there.
推荐答案
你应该在 app 文件夹内运行这个命令 'ng g c component-name'.
you should run this command 'ng g c component-name' inside is app folder.
1) cd src/app2) ng g c 组件名称
