全局安装 npm [英] Installing npm globally

问题描述

是否可以全局安装 npm，这是个好主意吗?

Is it possible to install npm globally and is this a good idea?

我使用 npm install 命令安装了 npm，并且能够运行 npm start.然后在将我的项目发布到 github 后，我想确保如果有人克隆它它会运行，所以我将它克隆到我机器上的不同目录.然后我不得不再次运行 npm install 来安装依赖项.是否有必要为您在本地构建的每个项目都执行此操作，或者在您的机器上全局安装它是否更好且可能?

I installed npm with the npm install command and was able to run npm start. Then after publishing my project to github I wanted to make sure it would run if someone cloned it, so I cloned it to a different directory on my machine. I then had to run npm install again to install the dependencies. Is it necessary to do this for each project you build locally or is it better and possible to install it globally on your machine?

谢谢

一般来说，经验法则是:

In general, the rule of thumb is:

如果您要安装要在程序中使用的东西，使用 require('whatever')，然后在本地安装它，在根目录下您的项目.

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.

如果你正在安装你想在你的 shell 中使用的东西，在命令行什么的，全局安装，这样它二进制文件最终会出现在您的 PATH 环境变量中.

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.
