getting an error "SyntaxError: Unexpected string" near the import statement working with ts-node-dev

Question

我尝试将打字稿库与节点一起使用，但我不断收到这些语法错误。我是运行使用 ts-node-dev 形成 package.json 的开发脚本。错误显示在导入语句附近，我不确定它是否是我的 tsconfig.json 的问题（它也附在下面）。但我正在使用 "module":"commonjs" .

Answer 1

您正在导入您的模块import "./detectPackage.js";，这不是正确的方法。

以这种方式导入您的模块：

import SomeModule from "./detectPackage.js";

Answer 2

对于遇到此问题的任何人，这是我使用的 node.js 版本的问题，我使用的是早于 10 的版本，当将版本更新到 14+ 时，问题已解决。
