通过运行npm install create-react-app创建的node_modules文件夹有什么用？

Question

When I run npm install create-react-app in any folder, it creates a node_modules folder. What is the node_modules folder for? How is it related to create-react-app ?

Answer 1

create-react-app should be installed using npm install -g create-react-app that will make the create-react-app command available in any directory.

See the npm documentation for a complete description of the various folders that npm creates or writes to.

Whe you run npm install create-react-app (without the global ( -g ) modifier) npm executes a local dependency install and puts the results in ./node_modules of the current directory.

Answer 2

如果要避免创建node_modules目录，可以通过npm install -g create-react-app全局npm install -g create-react-app 。

Answer 3

Short answer: yes.

Long answer: create-react-app should be installed globally, then run inside the folder in which you wish to put your app.

Answer 4

基本上是包含您的应用程序所需的所有节点程序包的文件夹，nmp install create-react-app依赖于将安装在node_modules文件夹中的其他节点程序包。
