尝试使用官网给出的命令安装CLI，这是响应：

npm install -g @aws-amplify/cli

我已经安装了最新版本的 node 和 npm。解决这个问题真的很有帮助。 TIA

【解决方案1】：

阅读有关此类似错误的博文，作者建议安装 typescript，这将解决问题。遵循该建议，安装了 typescript 并安装了 aws cli，瞧！有效！。不知道如何，但它解决了我的问题。很想知道如何，如果有人知道这一点，请在您的回答中告诉我。 TIA

就我而言，我只需要在我的 Mac 命令行上的命令行请求前添加 sudo：

【解决方案3】：

我遇到了同样的问题。对我有用的是：

npm uninstall -g @aws-amplify/cli

npm install -g @aws-amplify/cli

在所有这些过程中，确保您的 PC 已连接到互联网。如果可能，不要最小化窗口，等到一切都正确安装。
