更新程序:

ng --version
angular-cli: 1.0.0-beta.15
node: 6.5.0
os: linux x64

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

在我的项目目录下:

rm -rf node_modules dist tmp
npm install --save-dev angular-cli@latest
ng init                                         <-- failure here

推荐答案

将项目的 @angular 从 2.0.1 降级到 2.0.0> 通过编辑 package.json，然后:

Downgrade the project's @angular from 2.0.1 to 2.0.0 by editing package.json, then:

rm -rf node_modules
npm install

然后 ng init 再次起作用；然后，您可以升级到@angular 2.0.1.

Then ng init works, again; and then, you can upgrade to @angular 2.0.1.
