由于某些原因，在我的机器上使用npm install -g express全局安装Express后，如果我cd到一个目录并尝试运行express，我会得到以下错误：

express: command not found.

即使我用sudo运行它，我仍然得到相同的输出。我已经尝试了多种不同的解决方案来解决这个问题，但都没有奏效。我已经通过homebrew安装了node，Stack Overflow上的一些线程指出这可能是一个问题，所以我完全卸载了node，并通过nodejs.org上的安装程序重新安装(我现在运行的是v0.10.26)，问题仍然存在。

如果我进入我的本地速成版，它就在那里，但是在/ /usr/local/lib/node_modules /local/bin中没有任何关于速成版的内容。我不确定这是不是一个问题，但考虑到该目录中有其他全局安装的节点包的二进制文件，我认为那里可能有问题。

这是我在安装时得到的确切输出：

随着Express4.0.0的发布，看起来你需要做sudo npm install -g express-generator。

您需要运行以下命令：

npm install -gd express-generator

原来的express带有cli，现在cli拆分成单独的express-generator包。原来由项目生成的是运行快捷节点app.js，因为httpserver中的相关代码在app.js中，而现在这部分代码放到了项目目录bin/www下面，app.js只保留了实现app逻辑的代码，需要运行bin/www。只是一个非常简单的应用程序和精细化包依赖版本的变化。
