没有findExpress命令
由于某种原因，在我的机器上使用npm install -g express在全局安装Express之后，如果我进入一个目录并尝试运行Express，出现以下错误：
express: command not found.
即使我用sudo运行，我仍然得到相同的输出。 我已经尝试了多个不同的解决scheme来解决这个问题，没有什么工 我已经通过homebrew安装了堆栈溢出的一些线程可能是一个问题，所以我完全卸载节点，并通过nodejs.org（我现在运行v0.10.26）安装程序重新安装节点，问题仍然存在。
如果我进入我的/usr/local/lib/node_modules Express中，但在/ usr / local / bin中，Express没有任何内容。 我不知道这是否是一个问题，但考虑到在该目录中有其他全局安装的节点包的二进制文件，我认为可能有错误的地方。
这是我安装时得到的确切输出：

随着Express 4.0.0的发布，它看起来像你需要做sudo npm install -g express-generator 。
你需要运行：
npm install -gd express-generator
原来用cli表示，现在cli分成独立的express-generator包。 本来生成的项目运行的是express节点app.js，因为httpserver在app.js中有相关的代码，现在这部分代码到工程目录bin/www下面，app.js只保留实现app逻辑代码，你需要运行bin/www 。 只是一个非常简单的应用程序和优化包依赖版本的变化。
