Answer 1

您是否尝试过在命令前添加 sudo ？

sudo npm install -g create-react-app

Answer 2

运行此命令首先纠正 /usr/local 下的文件所有权：

sudo chown -R $(id -un):$(id -gn) /usr/local/*

然后重新运行 npm install...

Answer 3

你为什么要安装这个？

如果您安装了 npm 和节点，您只需运行在您希望创建项目的文件夹中执行以下命令。

注意开头是 NPX 而不是 NPM，这不是错误

npx create-react-app <your app name here>
