如何修复 amplify CLI 错误：“-bash: amplify: 找不到命令”

Question

我在我的笔记本电脑上安装了 amplify cli，尽管它抛出了错误，但我还是使用了该amplify configure命令并且它有效。但现在，当我尝试在另一台笔记本电脑上执行相同的操作时，它会抛出错误“-bash：amplify：找不到命令”。以下是整个错误块：

放大命令在另一台笔记本电脑上运行完全正常，该笔记本电脑出现与上述相同的错误。npm install -g @aws-amplify/cli --unsafe-perm=true我什至尝试按照 GitHub 上用户的建议安装 cli 。如果有人能帮我解决这个问题那就太好了。TIA

Answer 1

在花费了大量时间尝试分析错误之后，以下内容终于对我有用：

1. 安装的打字稿

2. 添加/usr/local/bin/node和/usr/local/bin/npm到路径中

3. 确保管理员有权使用以下命令访问该文件：

   sudo chown -R ownername: /usr/local/lib/node_modules

4. 最后使用以下命令安装了 amplify：

sudo npm install -g @aws-amplify/cli --unsafe-perm=true

通过遵循这些步骤，即使我遇到错误，放大命令仍然可以工作。
