要在当前目录中安装 package.json 的软件包，您需要运行 npm install 命令。
是否可以在特定文件夹中安装 package.json 的软件包，而无需转到该文件夹？`
已经找到了 Bower 和 gulp 任务的解决方案:
bower install --config.cwd=<directory>
gulp build --cwd <directory>
但缺少 npm 的类似功能
当我运行命令时:npm install --prefix C:\Users\ng\Projects\Lottery\src\SPA
我看到一个错误:
npm ERR! addLocal Could not install C:\Users\ng\Projects

来自 documentation :
The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On windows, this is the exact location of the node.exe binary
最佳答案
这应该是解决方案:How to npm install to a specified directory?
基本上，您将前缀选项与全局选项一起使用:npm install --prefix <path/to/prefix_folder> -g
您还可以查看 documentation .
