typescript - 打字稿意外标记<

Question

我使用 mocha 从命令行测试 tsx 组件。我用于编译 ts-node 包。但它不能编译 jsx。我的 tsconfig.json 有 jsx 编译选项。

mocha --compilers ts:ts-node/register,tsx:ts-node/register,js:babel-core/register ./src/testing.tsx

SyntaxError：Exports.runInThisContext (vm.js:53:16) 处的意外令牌 <

tsconfig.json ：

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "module": "commonjs",
    "jsx": "preserve",
    "target": "es6",
    "removeComments": true,
    "preserveConstEnums": true,
    "sourceMap": false,
    "noEmitHelpers": false,
    "noEmitOnError": false,
    "noImplicitAny": false
  },
  "exclude": [
    "babel_cache",
    "build",

    "out",
    "test",
    "tools",
    "typings"
  ],
  "compileOnSave": false,
  "buildOnSave": false
}

/src/testing.tsx ：

import * as React from 'react';
class Foo extends React.Component<any, any> {
    render () {
        return <span>yep</span>;
    }
}
<Foo />
