处理SyntaxError -local-storage/contex.js

Question

我正在尝试使用Rollup生成一个树摇动的、精简的脚本，以部署到AWS Lambda。然而，由于某些原因，rollup似乎被choking local-storage库阻塞了。

错误：

    'changed in 2.7: no default context',
  watchFiles: [
    ...
  ]
}

违规代码(continuation local-storage/context.js第17行，位置0)是：

function Namespace(name) {

我不明白这里怎么会有语法错误：

我通过javascript api运行rollup，因为我需要以编程方式生成输入，这是我调用构建的地方：

try {
    const build = await rollup({
      external: ['aws-sdk', ...builtinModules],
      input,
      plugins: [
        commonjs(),
        nodeResolve({ extensions: ['.ts', '.js', '.json', '.node', '.mjs'] }),
        json(),
        babel({ extensions: ['.ts'], babelHelpers: 'bundled' })
      ]
    });
    await build.write({
      dir: outDir,
      format: 'cjs',
      entryFileNames: '[name].js',
      sourcemap: false
    });
  } catch (err) {
    console.log(err);
    throw err;
  }

如果其他人遇到这个问题，有一种解决方法：

https://github.com/rollup/plugins/issues/202

添加替换：

plugins: [
  replace({"if (!process.addAsyncListener) require('async-listener": "require('async-listener"})
]
