在尝试使用和不使用 sudo 安装 Express-Generator 时，我遇到了一个非常奇怪的错误。
我需要运行:npm installexpress-generator -g，然后运行express --ejs name_here，但是在执行第一个命令时，出现以下错误:
npm ERR! Darwin 15.2.0
npm ERR! argv "node" "/usr/local/bin/npm" "install" "express-generator" "-g"

尝试sudo npm installexpress-generator -g后我得到了这个:
/Users/[name]/.npm/bin/express -> /Users/[name]/.npm/lib/node_modules/express-generator/bin/express
express-generator@4.13.1 /Users/[name]/.npm/lib/node_modules/express-generator
├── sorted-object@1.0.0
├── commander@2.7.1 (graceful-readlink@1.0.1)
└── mkdirp@0.5.1 (minimist@0.0.8)
然后运行 express --ejs name_here 返回 -bash:express: command not find
有什么办法可以解决这个问题吗？关于 SO 的其他问题似乎通过尝试 sudo 解决了这个问题，但不适合我。
最佳答案
尝试使用带有完整路径的 express 命令:/Users/[name]/.npm/bin/express 或 sudo/Users/[名称]/.npm/bin/express.
看起来安装后未设置PATH变量。 (https://en.wikipedia.org/wiki/PATH_(variable))
