您能帮我这个######################################## ################################################ ###############
答案 0 :(得分：5)
今天，我尝试更新expo-cli并收到相同的错误。因此，我再次安装了旧版本。您可以尝试一下，它对我有用。
npm i -g expo-cli@3.5.0
编辑：
现在，Expo-CLI Github页面上有一个bug report，有人建议运行npm install --global --production windows-build-tools，然后安装最新版本的Expo。此npm软件包将安装Visual C ++ Build Tools和Python 2.7。如果您想要最新版本的Expo，可以尝试一下。
答案 1 :(得分：1)
似乎这里可能有很多问题，我认为没有简单的答案就足够了。
将需要知道您在哪个环境中运行命令
话虽如此，您可以使用来自GitHub问题线程的建议，并简单尝试并使用npx
npx expo init {my-project}
答案 2 :(得分：1)
改为运行以下命令。
yarn global add expo-cli
答案 3 :(得分：0)
对我来说，发生了同样的事情，除了通过命令行卸载expo-cli外，我还必须手动卸载c / users下的.expo文件夹以及C下的任何expo和expo-cli相关文件： \ Users \ MyUser \ AppData \ Roaming \ npm。只有这样，当安装旧版本的expo（3.5.0）时，它才能再次开始工作。
