typescript - 严格模式不允许分配给未定义的变量

Question

使用tsdx构建 TypeScript 并使用NUglify进行缩小后，我开始收到错误消息。Strict-mode does not allow assignment to undefined variables: regeneratorRuntime

try {
  regeneratorRuntime = runtime;
} catch (accidentalStrictMode) {
  // This module should not be running in strict mode, so the above
  // assignment should always work unless something is misconfigured. Just
  // in case runtime.js accidentally runs in strict mode, we can escape
  // strict mode using a global Function call. This could conceivably fail
  // if a Content Security Policy forbids using Function, but in that case
  // the proper solution is to fix the accidental strict mode problem. If
  // you've misconfigured your bundler to force strict mode and applied a
  // CSP to forbid Function, and you're not willing to fix either of those
  // problems, please detail your unique predicament in a GitHub issue.
  Function("r", "regeneratorRuntime = r")(runtime);
}
});

如何修复此错误而不必忽略它？
