无法启动世博项目

Question

当我尝试使用 expo start 时，我的 expo 项目没有启动。

节点版本 - v12.18.1 世博版-3.21.10

当我运行expo start:

Error: react-native is not installed. Please run `npm install` or `yarn` in your project directory.
Couldn't start project. Please fix the errors and restart the project.
Error: Couldn't start project. Please fix the errors and restart the project.
    at startExpoServerAsync (C:\@expo\xdl@57.9.18\src\Project.ts:2070:11)
    at Object.startAsync (C:\@expo\xdl@57.9.18\src\Project.ts:2384:5)
    at action (C:\Users\Admin\AppData\Roaming\npm\node_modules\expo-cli\src\commands\start.ts:181:3)
    at C:\Users\Admin\AppData\Roaming\npm\node_modules\expo-cli\src\commands\start.ts:354:16
    at Command.<anonymous> (C:\Users\Admin\AppData\Roaming\npm\node_modules\expo-cli\src\exp.ts:80:7)

然后我跑了上面错误中提到的npm install，然后得到了这个错误

    npm ERR! code ERR_OSSL_PEM_NO_START_LINE
    npm ERR! error:0909006C:PEM routines:get_name:no start line
