1.这是官方的运行指南： https://github.com/expressjs/generator

2.我在windows下的操作过程：

E:>npm install -g express-generator npm http GET https://registry.npmjs.org/express-generator npm http 200 https://registry.npmjs.org/express-generator npm http GET https://registry.npmjs.org/express-generator/-/express-generator-4.9.0.tgz npm http 200 https://registry.npmjs.org/express-generator/-/express-generator-4.9.0.tgz npm http GET https://registry.npmjs.org/commander/1.3.2 npm http GET https://registry.npmjs.org/mkdirp/0.5.0 npm http 304 https://registry.npmjs.org/commander/1.3.2 npm http 304 https://registry.npmjs.org/mkdirp/0.5.0 npm http GET https://registry.npmjs.org/keypress npm http GET https://registry.npmjs.org/minimist/0.0.8 npm http 304 https://registry.npmjs.org/keypress npm http 304 https://registry.npmjs.org/minimist/0.0.8 C:\Users\Lenovo\AppData\Roaming\npm\express -> C:\Users\Lenovo\AppData\Roaming\npm\node_modules\express-generator\bin\express express-generator@4.9.0 C:\Users\Lenovo\AppData\Roaming\npm\node_modules\express-generator ├── commander@1.3.2 (keypress@0.1.0) └── mkdirp@0.5.0 (minimist@0.0.8)

E:>express /tmp/foo && cd /tmp/foo ’express’ 不是内部或外部命令，也不是可运行的程序 或批处理文件。

E:>express -h ’express’ 不是内部或外部命令，也不是可运行的程序 或批处理文件。

E:>

2.发现当输入express命令则出错，如何绑定或者让命令行发现这个express命令，请赐教！
