The first path in the path variable needs to be the NPM path. Opening the Node.js command prompt I found that the ng command worked there. I dug into the shortcut and found that it references a command to ensure the first Path variable is NPM. To Fix:
path 变量中的第一个路径需要是 NPM 路径。打开 Node.js 命令提示符，我发现 ng 命令在那里工作。我深入研究了快捷方式，发现它引用了一个命令来确保第一个 Path 变量是 NPM。修理：
- Right Clicked on My Computer (windows)
- Selected Advanced System Settings
- Clicked "Environment Variables"
- Under "Path" variable, made the FIRST value listed
%AppData%\npm
- 右键单击我的电脑（Windows）
- 选定的高级系统设置
- 点击“环境变量”
- 在“路径”变量下，列出第一个值
%AppData%\npm
Once I did that I was able to close powershell and reopen and all worked.
一旦我这样做了，我就能够关闭powershell并重新打开并且一切正常。

You just need to close the visual studio code and restart again. But to get the ng command work in vs code, you need to first compile the project with cmd in administrator mode.
您只需要关闭 Visual Studio 代码并重新启动。但是要让 ng 命令在 vs code 中工作，你需要先在管理员模式下用 cmd 编译项目。
