npm安装不在/ usr/bin安装东西

Question

我正在尝试安装SailsJS:

$ sudo npm install -g sails

它可以使用以下日志在/ home/brunoluiz/npm/lib/node_modules/sails中安装所有内容:

问题是当你尝试使用风帆时:sails new project例如,你运行并且它没有找到风帆.稍微调查一下,我发现npm没有在/ usr/bin安装模块.这有什么理由吗？一些配置？

Karma模块也是如此.

我使用了ppa中的nodejs,创建了node的符号链接,并从官方install.sh脚本(https://www.npmjs.org/install.sh)安装了npm .

听起来您的npm安装配置为使用/home/brunoluiz/npmas prefix,这意味着它会将符号链接放置到全局安装的软件包附带的CLI中{prefix}/bin.

在默认安装,prefix或者是/usr或/usr/localUnix平台(%APPDATA%/npm在Windows上).

如果{prefix}/bin不在您的$PATH身上,您将无法仅通过名称执行此类CLI.

要查看当前有效的prefix值,请运行:

npm get prefix

你的选择是:

• 加入/home/brunoluiz/npm/bin你的$PATH

• 将prefix配置项的值更改为其bin子文件夹已在您的文件夹中$PATH; 例如:

    npm set prefix /usr       # Ubuntu; CLI symlinks are placed in /usr/bin
    npm set prefix /usr/local # OSX; CLIs symlinks are placed in /usr/local/bin

但请注意,您必须重新安装要在新{prefix}\bin位置创建的符号链接的全局包.
