react-native - npm install -g expo-cli ，安装错误

Question

我使用以下命令安装 npm 以创建我的 react-native 项目

npm install -g expo-cli 

但不幸的是我无法安装它。它给出了以下错误。

我如何解决这个错误？

Answer 1

尝试npm install -g expo-cli从终端运行

Answer 2

我尝试使用安装 npm，npm install但它给出了以下警告。

npm WARN saveError ENOENT: no such file or directory, open 'F:\ucsc\3rd year\Mobile Application Development\lec. notes\abc\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 'F:\ucsc\3rd year\Mobile Application Development\lec. notes\abc\package.json'

因此我使用npm install -g npm. 它安装成功

在我安装 expo-cli 后使用npm install -g expo-cli 它成功安装
