Question

我收到此错误＆amp;无法找到任何理由。

我已在 amazon aws 上部署了此代码。是由于代码的异步执行？ Stackoverflow说我要添加更多细节，但我没有更多。

以下是我的代码的快照。

     .then(res=>{

    .then(()=>{

    rclient.quit();

  })

  .catch(err=>{
   console.log(err.stack);
    console.log("error occured");

}

节点版本Undefined symbols for architecture x86_64: "FooBar::FooBar()", referenced from: _main in main-c0378e.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)因该错误而闻名，请下载最新版本。要么使用LTS v4.3.2，要么使用version(6.10.0)版本不再维护的最新版本。这些版本是稳定的，应该可以使用。
