我正在尝试使用以下命令在Red Hat Enterprise Linux Server 6.1上安装node.js:

sudo yum install nodejs npm

我收到以下错误:

Error: Package: nodejs-0.10.24-1.el6.x86_64 (epel)
           Requires: libssl.so.10(libssl.so.10)(64bit)
Error: Package: nodejs-devel-0.10.24-1.el6.x86_64 (epel)
           Requires: libcrypto.so.10(libcrypto.so.10)(64bit)

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我也尝试了以下命令:

sudo yum install -y nodejs

我收到以下错误:

Error: Package: nodejs-0.10.24-1.el6.x86_64 (epel)
           Requires: libssl.so.10(libssl.so.10)(64bit)
Error: Package: nodejs-0.10.24-1.el6.x86_64 (epel)
           Requires: libcrypto.so.10(libcrypto.so.10)(64bit)

我该如何安装？我想安装最新版本.

目前我查询ES的单个键值对,如下所示:

String query_key = "abc";
String query_val = "def";

searchRequestBuilder.setQuery(QueryBuilders.matchQuery(query_key, query_val)).execute().actionGet();

现在,我没有单个键值对,而是具有以下键值对映射: Map<String,String> query_list

我如何为此修改相同的内容？

我正在使用 nodemailer 在 nodejs 中发送电子邮件。我可以发送邮件，但脚本不会终止。我不知道如何关闭连接。

这是代码：

var nodemailer = require('nodemailer');
nodemailer.SMTP = {
  host: 'localhost'
}
nodemailer.send_mail(
{
    sender: 'me@example.com',
    to:'my_gmail_nickname@gmail.com',
    subject:'Hello!',
    html: 'test',
    body:'test'
},
function(error, success){
    console.log(error);
    console.log(success);
    console.log('Message ' + success ? 'sent' : 'failed');
});

我已将索引名称从“sample1”更改为“sample2”，但在完成此操作后，我在弹性搜索中索引记录时遇到异常：
