npm package.json全局安装？

Question

Is there any way to set an NPM dependency to be installed globally in the package.json file?

Whenever I run npm update all the dependencies are installed locally.

Thanks.

Answer 1

我相信-g选项会导致全局安装。

Answer 2

Is your reason for installing globally in order to make new scripts available on the command line? If so, I might have a workaround for you.

Just install your packages as usual (without the -g ):

npm install -S my_module_name

Including the -S flag or --save will help keep your package.json file up to date.

As usual, your project's npm install step will install locally (as you have described). However, it will also produces a local folder containing symlinks to each of the project's npm-supplied command-line executables (located inside the node_modules/.bin/ folder).

Add that folder to your system path to enable command-line access to npm modules without requiring installation via -g , or root access to a machine:

export PATH=/path/to/your/project/source/node_modules/.bin/:$PATH
