我现在正在Windows上学习nodejs。有几个模块是通过npm全局安装的。nodejs无法找到已安装的模块。以玉为例,

npm install jade -g

Jade安装在“C:\Program Files (x86)\nodejs\node_modules”目录下,但下面的代码将失败,并提示“无法找到模块' Jade '”错误。

var jade = require('jade');

然而,当jade在本地安装时(npm中没有-g选项),代码将成功运行。我不想使用本地安装的模块,这对我来说是浪费磁盘空间。如何使全局安装的模块在Windows上工作?


当前回答

我在Windows 7上运行时遇到了这个问题

npm install -g gulp

以管理员身份登录,同时以普通用户身份登录。

解决方案:当以普通用户执行相同的安装时(而不是“以admin身份运行”cmd),一切正常。我猜这与默认的安装和搜索路径有关。

简而言之,在你的应用目录中使用npm link jade。

对于Windows 10,我必须在本地安装gulp文件夹:

C:\Users\myaccount\AppData\Roaming\npm\ node_modules

npm install gulp

这修复了我的“吞咽不被识别”的问题

我将引用这个节点的博客文章…

In general, the rule of thumb is: If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project. If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable. ... Of course, there are some cases where you want to do both. Coffee-script and Express both are good examples of apps that have a command line interface, as well as a library. In those cases, you can do one of the following: Install it in both places. Seriously, are you that short on disk space? It’s fine, really. They’re tiny JavaScript programs. Install it globally, and then npm link coffee-script or npm link express (if you’re on a platform that supports symbolic links.) Then you only need to update the global copy to update all the symlinks as well.

我知道我可以唤醒一个僵尸,但我认为这仍然是一个问题,如果你需要全局访问Windows 7上的节点模块,你需要将这个添加到你的全局变量路径:

C:\Users\{USER}\AppData\Roaming\npm

重要的是:只有这个没有node_modules部分,我花了半个小时才看到这个。

从我使用win8.1的经验来看,npm在上面安装模块 C:\Users\【用户名】\ AppData \ \ npm \ node_modules徘徊 但他却继续搜索 C:\Users\【用户名】\ node_modules。

一个简单的解决方案参考模块在应用程序的全路径:

var jsonminify = require("C:/Users/Saulius/AppData/Roaming/npm/node_modules/jsonminify");
