NPM全局安装“无法找到模块”

我写了一个模块，不久前发布到npm (https://npmjs.org/package/wisp)

所以它可以从命令行安装:

I -g wisp

然而，当我从命令行运行它时，我一直得到一个错误，乐观主义者没有安装:

$ wisp 
Error: Cannot find module 'optimist'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:362:17)
    at require (module.js:378:17)
    at Object.<anonymous> (/usr/local/lib/node_modules/wisp/wisp:12:10)
    at Object.<anonymous> (/usr/local/lib/node_modules/wisp/wisp:96:4)
    at Module._compile (module.js:449:26)
    at Object.exports.run (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/coffee-script.js:68:25)
    at compileScript (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:135:29)
    at fs.stat.notSources.(anonymous function) (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:110:18)

但是，我已经在包中指定了。Json作为依赖项:

{
  "name": "wisp",
  "author": "Brendan Scarvell <bscarvell@gmail.com>",
  "version": "0.1.0",
  "description": "Global nodejs file server",
  "dependencies": {
    "optimist": "~0.3.4"
  },
  "repository": "git://github.com/tehlulz/wisp",
  "bin": {
    "wisp" : "./wisp"
  }
}

有人知道怎么才能让它运行起来吗?我知道这与bin部分添加可执行文件到bin和该目录中的node_modules为空有关。不知道怎么解决。

当前回答

对于Windows，从Nodejs无法找到安装在Windows上的模块?对我有用的是运行NPM link

npm link wisp

其他回答

对于其他遇到这个问题的人，我有这个问题，因为我的npm安装到一个不在我的NODE_PATH上的位置。

[root@uberneek ~]# which npm
/opt/bin/npm
[root@uberneek ~]# which node
/opt/bin/node
[root@uberneek ~]# echo $NODE_PATH

我的NODE_PATH是空的，运行npm install——global——verbose promises -io显示它正在安装到/opt/lib/node_modules/ promises -io:

[root@uberneek ~]# npm install --global --verbose promised-io
npm info it worked if it ends with ok
npm verb cli [ '/opt/bin/node',
npm verb cli   '/opt/bin/npm',
npm verb cli   'install',
npm verb cli   '--global',
npm verb cli   '--verbose',
npm verb cli   'promised-io' ]
npm info using npm@1.1.45
npm info using node@v0.8.4
[cut]
npm info build /opt/lib/node_modules/promised-io
npm verb from cache /opt/lib/node_modules/promised-io/package.json
npm verb linkStuff [ true, '/opt/lib/node_modules', true, '/opt/lib/node_modules' ]
[cut]

我的脚本在require(' promises -io/promise')上失败:

[neek@uberneek project]$ node buildscripts/stringsmerge.js 

module.js:340
    throw err;
          ^
Error: Cannot find module 'promised-io/promise'
    at Function.Module._resolveFilename (module.js:338:15)

我可能使用configure——prefix=/opt从源代码安装了node和npm。我不知道为什么这使得他们无法找到已安装的模块。现在的修复是将NODE_PATH指向正确的目录:
