無法安裝AngularJs2

Question

自從我使用npm或節點以來已經有一段時間了。我試圖安裝angularjs2，學習它，當我嘗試安裝時，我得到了以下錯誤。我也嘗試再次更新npm或安裝nodejs，清理緩存（強制清理）不行。這個問題的任何修復？

我想通了這個問題。 我激活了節點版本0.9，並且由於在我的MAC OSX上使用packager node-v4.6.0.pkg進行安裝時，即使是最新版本的節點也未激活最新版本。如果你有HomeBrew，會發生這種情況。即使我做了乾淨的卸載並安裝節點，也沒有發生更新到最新節點版本的問題。 所以，我想下面的步驟，這修復了這個問題

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

安裝Angular2。我通過創建應用程序並運行'ng serve'進行測試，結果很有效！
