反应安装后找不到create-react-app

Question

尝试启动React App并获取此功能。

ZeroCalm$ create-react-app hello-world
-bash: create-react-app: command not found

我尝试安装并获取：

ZeroCalms-MacBook-Pro:reactProjects ZeroCalm$ sudo npm install create-
react-app
Password:
npm WARN saveError ENOENT: no such file or directory, open 
'/Users/ZeroCalm/package.json'
npm notice created a lockfile as package-lock.json. You should commit 
this file.
npm WARN enoent ENOENT: no such file or directory, open 
'/Users/ZeroCalm/package.json'

+ create-react-app@1.5.2
added 97 packages in 6.312s

尝试创建反应应用：

ZeroCalms-MacBook-Pro:reactProjects ZeroCalm$ create-react-app hello-
world
-bash: create-react-app: command not found

尝试将global标记添加到npm install命令。

sudo npm install -g create-react-app

这会将create-react-app保存为您可以在任何地方使用的全局包（see docs for more info about npm install here）。
