快遞找不到命令

Question

出於某種原因與npm install -g express我的機器上全局安裝快車後，如果我cd到一個目錄，並嘗試運行表現，我得到以下錯誤：

express: command not found. 

即使我sudo運行我仍然得到相同的輸出。我已經嘗試了多種不同的解決方案來解決這個問題，並沒有任何工作。我已經通過homebrew安裝了節點，Stack Overflow上的一些線程可能是一個問題，所以我完全卸載節點並通過nodejs.org上的安裝程序重新安裝（我現在正在運行v0.10.26），問題仍然存在。

如果我進入我的/usr/local/lib/node_modules Express在那裏，但在/ usr/local/bin中，Express沒有任何內容。我不確定這是否有問題，但考慮到該目錄中有其他全局安裝的節點軟件包的二進制文件，我認爲可能存在某些問題。

這是當我安裝了精確的輸出我得到：

Answer 1

隨着快速的發佈4.0.0，它看起來像你需要做的sudo npm install -g express-generator。

Answer 2

你需要運行：

npm install -gd express-generator 

原來的快遞與CLI，現在CLI拆分成獨立的快遞發電機包。本來由項目生成的是運行express節點app.js，因爲httpserver在app.js中的相關代碼，現在這部分代碼到工程目錄bin/www下面，app.js只保留實現app邏輯代碼，需要運行bin/www。只是一個非常簡單的應用程序和優化包依賴版本更改。
