你能帮我解决这个问题吗######################################### ############################################### #############
最佳答案
今天我尝试更新我的 expo-cli 并遇到了同样的错误。所以我又安装了一个旧版本。你可以试试这个，它对我有用。
npm i -g expo-cli@3.5.0
编辑:
现在有一个 bug report在 Expo-CLI Github 页面上，有人建议运行
npm install --global --production windows-build-tools然后安装最新版本的Expo。这个 npm 包安装了 Visual C++ 构建工具和 Python 2.7。如果你想要最新版本的 Expo，你可以试试这个。
关于react-native - 使用 npm install -g expo-cli 安装 react native expo 的问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58877392/
