推荐答案

首先，验证你的 NPM 缓存内存

First ,verify your NPM cached memory

npm cache verify

然后尝试:

npm cache clean --force
npm install –g @angular/cli@latest 
ng new <YourProjectName>

如果问题仍然存在，请尝试以下操作

If the problem persists, then try the following

npm cache clean --force
npm update
ng new <YourProjectName>

注意

正如@0210vidit 在下面的评论中所说:

不要在命名中使用破折号(-)或(.)

NOTE

As @0210vidit said in the comment below:

do not use dash(-) or (.) in naming
