全局安装NPM软件包时的行为不一致

我试图在Ubuntu（12.04）上安装NPM软件包。我已经通过Chris Lea's PPA repository安装了Node.js和NPM。全局安装NPM软件包时的行为不一致

我试图将Uptime project部署到我的服务器。我已经克隆了GitHub上的应用程序，然后试图安装该应用程序依赖作为根用户：

所有好看的包似乎成功安装。然而，当我检查，如果NPM软件包的依赖关系得到满足，我收到了一堆满足的依赖关系的上市，就像我没有哪怕只是一秒钟前安装：

据我所知（但是纠正我，如果我错了）在全局安装包时，NPM尊重NODE_PATH环境变量。有趣的是，如果你看看上面的软件包安装输出，你可以看到NPM在全局安装了依赖软件包/usr/lib/node_modules。如果我仔细检查了NODE_PATH环境变量，但事实证明，NODE_PATH变量设置不同：

[email protected]:/web/my-application# echo $NODE_PATH 
/usr/lib/nodejs:/usr/share/javascript

一件事澄清：我不知道该怎么NODE_PATH变量已定，我没有把它设置我自己，我有一种感觉，当我安装Node和NPM时，它带有Ubuntu软件包。

然后，我决定明确设置NODE_PATH变量，并仔细检查相关性：

[email protected]:/web/my-application# export NODE_PATH=/usr/lib/node_modules 
[email protected]:/web/my-application# npm list 
npm WARN mongoose 2.5.11 Unmet dependency in /web/my-application

    └── UNMET DEPENDENCY xmlhttprequest 1.2.2

仍然没有成功，但是当我试图运行与节点的应用程序，它成功地初始化并运行：

[email protected]:/web/my-application# node app.js 
Monitor origin started 
    info - socket.io started 
Express server listening on port 8082 in development mode 
Mongoose: pings.ensureIndex({ timestamp: -1 }) {}

Mongoose: checkdailystats.ensureIndex({ timestamp: -1, check: 1 }) { unique: true } 
Mongoose: checkmonthlystats.ensureIndex({ timestamp: -1, check: 1 }) { unique: true } 
Mongoose: checks.find({ '$where': 'function() {\n if (this.isPaused) return false;\n if (!this.firstTested) return true;\n var delay = (this.lastTested.getTime() - this.firstTested.getTime()) % this.interval;\n return (Date.now() - this.lastTested.getTime() + delay) >= (this.interval || 60000);\n}' }) { fields: { qos: 0 }, safe: true } 
Mongoose: taghourlystats.ensureIndex({ timestamp: -1, name: 1 }) { unique: true } 
Mongoose: tagdailystats.ensureIndex({ timestamp: -1, name: 1 }) { unique: true } 
Mongoose: tagmonthlystats.ensureIndex({ timestamp: -1, name: 1 }) { unique: true } 
Mongoose: tags.ensureIndex({ name: 1 }) { unique: true }

这看起来将是确定从现在开始，但是我绝对不会去运行应用程序的根，所以我需要在全球NPM包被认可的时候，我会运行的应用程序作为专用用户。

我有一种感觉，NPM在安装软件包时有某种不一致的行为。全局安装时，它会成功运行，但之后无法检索。

我该怎么办，还有，NODE_PATH环境变量如何看起来像？

你必须安装它只有npm install -d，没有-g。软件包的要求对于每个软件包都是本地的（因此，当您依赖于a和node_modules\a\node_modules\b，当a依赖于b时，您拥有node_modules\a）。

查看http://npmjs.org/doc/faq.html#I-installed-something-globally-but-I-can-t-require-it了解更多详情。

我想这应该是公认的答案，因为它解决了我的问题。只要进入你的模块的文件夹，并在那里安装依赖。 – Carlton

对不起，我花了一段时间才回到了stackoverflow。确认并接受了答案。感谢pentaur。 –

对我来说这是通过使用下面的命令来解决 -

NPM安装-d [email protected]。4 --registry http://registry.npmjs.org/

这肯定是'npm'中的一个错误，肯定传入默认的注册表不应该影响安装的方式。我很抱歉，但我不打算为这个答案投票，因为它不能解释为什么我上面的尝试不起作用。 –

清除缓存为我工作

npm cache clean
