我只是尝试安装Netbeans，但JDK有更多问题 [英] I just try to install Netbeans but there are more probs with JDK

问题描述

我在ubuntu上是新的，我想使用netbeans.我从其网站下载了netbeans，然后将此命令写到了该行

im new at ubuntu and i want to use netbeans. I downloaded netbeans from its web site then I wrote this commands to the line

 hakki@hakki-K55VM:~/Downloads$ chmod +x netbeans-7.4-linux.sh

 hakki@hakki-K55VM:~/Downloads$ sudo bash netbeans-7.4-linux.sh

 [sudo] password for hakki:

Configuring the installer...
Searching for JVM on the system...
Java SE Development Kit (JDK) was not found on this computer
JDK 7 is required for installing the NetBeans IDE. Make sure that the JDK is properly installed and run installer again.
You can specify valid JDK location using --javahome installer argument.

To download the JDK, visit http://www.oracle.com/technetwork/java/javase/downloads

收到上述通知后，我尝试使用这些命令安装JDK

After I get above notification I tried to install JDK with these commands

 hakki@hakki-K55VM:~$ sudo apt-get install openjdk-7-jre-headless
 .... 

 done

然后我控制了jdk的正确安装，并在下面的行中返回了

then I controled jdk installed properly and it returned below lines

 hakki@hakki-K55VM:~$ java -version

java version "1.7.0_51"
OpenJDK Runtime Environment (IcedTea 2.4.4) (7u51-2.4.4-0ubuntu0.13.10.1)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

下载jdk之后，我尝试再次安装netbeans，但仍然返回错误，并且无法初始化UI.我该如何解决这个问题?

After I download jdk I tried to install netbeans again but still it returns error and it cant initialize UI. How can I solve this problem?

 hakki@hakki-K55VM:~/Downloads$ sudo bash netbeans-7.4-linux.sh

推荐答案

NetBeans表示它需要JDK(Java开发工具包)，但是您仅安装了JRE(Java运行时环境).

The NetBeans says it needs a JDK (Java Development Kit), but you only installed a JRE (Java Runtime Environment).

我尝试使用这些命令安装JDK

I tried to install JDK with these commands

   hakki@hakki-K55VM:~$ sudo apt-get install openjdk-7-jre-headless

您安装的是JRE，而不是JDK.

You installed a JRE, not JDK.

这应该足够了

sudo apt-get install openjdk-7-jdk
