无法安装AngularJs2

Question

自从我使用npm或节点以来已经有一段时间了。我试图安装angularjs2，学习它，当我尝试安装时，我得到了以下错误。我也尝试再次更新npm或安装nodejs，清理缓存（强制清理）不行。这个问题的任何修复？

我想通了这个问题。 我激活了节点版本0.9，并且由于在我的MAC OSX上使用packager node-v4.6.0.pkg进行安装时，即使是最新版本的节点也未激活最新版本。如果你有HomeBrew，会发生这种情况。即使我做了干净的卸载并安装节点，也没有发生更新到最新节点版本的问题。 所以，我想下面的步骤，这修复了这个问题

nvm -v nvm ls nvm uninstall 0.9.6 nvm install 6.7.0 sudo npm install -g angular-cli@latest

安装Angular2。我通过创建应用程序并运行'ng serve'进行测试，结果很有效！
