NPM全局安装“找不到模块”
我写了一个模块,我刚才将其发布到npm(https://npmjs.org/package/wisp)
因此,可以从命令行进行安装:
$ npm i -g wisp
但是,当我从命令行运行它时,我不断收到未安装乐观主义者的错误消息:
$ 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 fs.stat.notSources.(anonymous function) (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:110:18)
但是,我在package.json中指定了依赖性:
{ "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"
}
}
有谁知道该怎么做才能使它运行?我知道它与bin部分有关,将可执行文件添加到bin中,该目录中的node_modules为空。不知道如何解决这个问题。
回答:
对于遇到此问题的其他任何人,由于我npm
将其安装到不在我的位置上而遇到了这个问题NODE_PATH
。
[root@uberneek ~]# which npm/opt/bin/npm
[root@uberneek ~]# which node
/opt/bin/node
[root@uberneek ~]# echo $NODE_PATH
我的NODE_PATH为空,运行npm install --global --verbose promised-
io显示它正在安装到中/opt/lib/node_modules/promised-io
:
[root@uberneek ~]# npm install --global --verbose promised-ionpm info it worked if it ends with ok
npm verb cli [ '/opt/bin/node',
npm verb cli '/opt/bin/npm',
npm verb cli 'install',
npm verb cli '--global',
npm verb cli '--verbose',
npm verb cli 'promised-io' ]
npm info using npm@1.1.45
npm info using node@v0.8.4
[cut]
npm info build /opt/lib/node_modules/promised-io
npm verb from cache /opt/lib/node_modules/promised-io/package.json
npm verb linkStuff [ true, '/opt/lib/node_modules', true, '/opt/lib/node_modules' ]
[cut]
我的脚本失败require('promised-io/promise')
:
[neek@uberneek project]$ node buildscripts/stringsmerge.jsmodule.js:340
throw err;
^
Error: Cannot find module 'promised-io/promise'
at Function.Module._resolveFilename (module.js:338:15)
我可能使用的源安装了node和npm configure
--prefix=/opt。我不知道为什么这使他们无法找到已安装的模块。现在的解决方法是将NODE_PATH指向正确的目录:
export NODE_PATH=/opt/lib/node_modules
我require('promised-io/promise')
现在成功了。
