Question

尝试使用和不使用sudo安装快速生成器时出现了一个非常奇怪的错误。

我需要运行：npm install express-generator -g然后express --ejs name_here但是在执行第一个命令时，我收到以下错误：

npm ERR! Darwin 15.2.0
npm ERR! argv "node" "/usr/local/bin/npm" "install" "express-generator" "-g"

尝试sudo npm install express-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会返回-bash: express: command not found

有没有办法可以解决这个问题？关于SO的其他问题似乎通过尝试sudo而不是为我来解决问题。

尝试使用带有完整路径的/Users/[name]/.npm/bin/express命令：sudo /Users/[name]/.npm/bin/express或PATH。

在安装后看起来{{1}}变量未设置。（https://en.wikipedia.org/wiki/PATH_(variable)）

-bash express：找不到命令
