Node.js 安装AWS Amplify CLI时出错

尝试使用官方网站上给出的命令安装CLI，以下是响应：

npm install -g @aws-amplify/cli

我已经安装了node和npm的最新版本。解决这个问题会非常有帮助。TIA阅读了一篇关于类似错误的博客文章，作者建议安装typescript，这将解决问题。按照这个建议，安装了typescript和aws cli，瞧！成功了！。不知道怎么做，但它解决了我的问题。好奇地想知道如何，如果有人知道这一点，请让我知道你的答案。TIA

在我的例子中，我只需在Mac命令行的命令行请求前面添加

sudo

：

sudo npm安装-g@aws-amplify/cli

可能重复的
