Express模块​​不可用

Question

我使用npm和-g选项安装了express模块​​。该命令显示在bash浏览器中但在节点终端中显示此错误。

require.resolve('express')
Error: Cannot find module 'express'
    at Function.Module._resolveFilename (module.js:339:15)
    at Function.require.resolve (internal/module.js:23:19)
    at repl:1:9
    at REPLServer.defaultEval (repl.js:252:27)
    at bound (domain.js:287:14)
    at REPLServer.runBound [as eval] (domain.js:300:12)
    at REPLServer.<anonymous> (repl.js:417:12)
    at emitOne (events.js:95:20)
    at REPLServer.emit (events.js:182:7)
    at REPLServer.Interface._onLine (readline.js:211:10)

我做错了什么？ 我也安装了快速发电机，但仍然不会

我的.bashrc文件包含以下条目：

export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"

在放置package.json
