全局安裝NPM軟件包時的行爲不一致

我試圖在Ubuntu（12.04）上安裝NPM軟件包。我已經通過Chris Lea's PPA repository安裝了Node.js和NPM。全局安裝NPM軟件包時的行爲不一致

我試圖將Uptime project部署到我的服務器。我已經克隆了GitHub上的應用程序，然後試圖安裝該應用程序依賴作爲根用戶：

所有好看的包似乎成功安裝。然而，當我檢查，如果NPM軟件包的依賴關係得到滿足，我收到了一堆滿足的依賴關係的上市，就像我沒有哪怕只是一秒鐘前安裝：

據我所知（但是糾正我，如果我錯了）在全局安裝包時，NPM尊重NODE_PATH環境變量。有趣的是，如果你看看上面的軟件包安裝輸出，你可以看到NPM在全局安裝了依賴軟件包/usr/lib/node_modules。如果我仔細檢查了NODE_PATH環境變量，但事實證明，NODE_PATH變量設置不同：

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

一件事澄清：我不知道該怎麼NODE_PATH變量已定，我沒有把它設置我自己，我有一種感覺，當我安裝Node和NPM時，它帶有Ubuntu軟件包。

然後，我決定明確設置NODE_PATH變量，並仔細檢查相關性：

[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

仍然沒有成功，但是當我試圖運行與節點的應用程序，它成功地初始化並運行：

[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: checkevents.ensureIndex({ timestamp: -1, check: 1 }) {} 
Mongoose: checkhourlystats.ensureIndex({ timestamp: -1, check: 1 }) { unique: true } 
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 }

這看起來將是確定從現在開始，但是我絕對不會去運行應用程序的根，所以我需要在全球NPM包被認可的時候，我會運行的應用程序作爲專用用戶。

我有一種感覺，NPM在安裝軟件包時有某種不一致的行爲。全局安裝時，它會成功運行，但之後無法檢索。

我該怎麼辦，還有，NODE_PATH環境變量如何看起來像？

你必須安裝它只有npm install -d，沒有-g。軟件包的要求對於每個軟件包都是本地的（因此，當您依賴於a和node_modules\a\node_modules\b，當a依賴於b時，您擁有node_modules\a）。

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

我想這應該是公認的答案，因爲它解決了我的問題。只要進入你的模塊的文件夾，並在那裏安裝依賴。 – Carlton

對不起，我花了一段時間纔回到了stackoverflow。確認並接受了答案。感謝pentaur。 –

對我來說這是通過使用下面的命令來解決 -

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

這肯定是'npm'中的一個錯誤，肯定傳入默認的註冊表不應該影響安裝的方式。我很抱歉，但我不打算爲這個答案投票，因爲它不能解釋爲什麼我上面的嘗試不起作用。 –

清除緩存爲我工作

npm cache clean
