'npm start' 启动循环以安装 expo-cli

Question

问题：我怎样才能让$ echo $PATH返回export PATH=~/.npm-global/bin:$PATH

背景故事：

1. 我在终端 (macOS Catalina) 上执行了npm install 并开始 在尝试npm start 时进入有关安装 expo cli 的循环。从那以后，我一直按照这里的说明进行操作： https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
   • 必须以source ~/.bash_profile 执行步骤 5（来自上面的链接） 尝试了npm start，但仍然陷入循环
2. 已经安装了 npm 6.13.4。但是，运行 npm start 会导致以下结果。请注意它是怎么说的 Expo CLI 已安装，但要求再次全局安装，所以我第二次说 n：

(base) MacBook-Pro:rn-starter user$ npm start

> @ start /Users/user/Desktop/REACT NATIVE/rn-starter
> expo start

This command requires Expo CLI.
Do you want to install it globally [Y/n]? Y
Installing the package 'expo-cli'...
Expo CLI installed. You can run `expo --help` for instructions.
This command requires Expo CLI.
Do you want to install it globally [Y/n]? n

1. 这是日志文件第 8 行的内容：

8 verbose lifecycle @~start: PATH: /usr/local/lib/node_modules/npm/node_modules/npm-lifecycle/node-gyp-bin:/Users/user/Desktop/REACT NATIVE/rn-starter/node_modules/.bin:/opt/anaconda3/bin:/opt/anaconda3/condabin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/usr/local/git/bin

4. 我以前安装过 Anaconda（几个月前）并使用 https://docs.anaconda.com/anaconda/install/uninstall/ 将其卸载但是，运行 $ echo $PATH 会导致 /opt/anaconda3/bin:/opt/anaconda3/condabin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/usr/local/git/bin

感谢任何可以提供帮助的建议！

您的package.json 文件怎么样？ 你的 npm start 必须是调用 expo
