是否有可能在项目之间共享node_modules目录 [英] Is it possible to have a node_modules directory shared between projects

问题描述

我有一个项目设置如下：

I have a project setup that is as follows:

workspace
└cache
  └node_modules
    └gulp (and gulp-plugins, express etc.)
└nodejs
  └node.exe
└project1
  └gulpfile.js
└project2
  └gulpfile.js

现在我想在项目目录中执行gulpfile：

Now I want to execute the gulpfile in the project directories:

set NODE_PATH='C:\workspace\cache\node_modules\'
cd C:\workspace\project1\
C:\workspace\nodejs\node.exe C:\workspace\cache\node_modules\gulp\bin\gulp.js watch

我得到以下输出：

[12:06:04] Local gulp not found in C:\workspace\project1
[12:06:04] Try running: npm install gulp

在两个项目文件夹中，gulp文件都是相似的，并使用一组类似的插件。我真的很想只有一次依赖（因为可能有多达25个项目共享相同的node_modules）。
这种设置是可能的，还是单独的项目目录需要有自己的node_modules文件夹？

In both project folders the gulpfile is similar and uses a similar set of plugins. I'd really like to have the dependencies only once (because potentially I have up to 25 projects sharing the same node_modules). Is this setup possible, or does the seperate project directories need to have their own node_modules folders?

推荐答案

Gulp要求您同时拥有全局安装和本地安装。所以你需要让你的Gulp相对于你的Gulp文件。如果您的 package.json 位于工作区和您的 node_modules 会在 workspace / node_modules 中，因为Node的搜索树，一切都会正常工作，但是如果你不能移动它们，唯一的方法就是假的 node_modules 文件夹。

Gulp requires you to have both a global installation as well as a local one. So you need to have your Gulp relatively to your Gulpfile. If your package.json would be located in workspace and your node_modules would be in workspace/node_modules everything would work fine because of Node's search tree, but if you can't move them, the only way to make it work is to "fake" the node_modules folder.

您可以通过创建符号链接来完成此操作。

You can do this by creating a symbolic link.

在Unix / Linux / Mac上：

Here's on Unix/Linux/Mac:

ln -s ../cache/node_modules node_modules

这是在Windows上的

Here's on Windows

mklink /D node_modules ../cache/node_modules

（后一个可能工作不同，我不在Win机器上）

(the latter one might work different, I'm not on a Win machine)
