Question

我正在运行Linux Mint 18.3肉桂64位

我刚刚下载了Apache NetBeans IDE 9.0

不需要运行任何脚本来安装它，我只需要运行以下命令来启动它：sudo /opt/netbeans/bin/netbeans 然后输入我的密码，netbeans打开。然后，我为该程序启动了一个启动器，因为我不想每次打开netbeans时都键入命令和密码。但是发射器没有工作。我意识到我没有在启动程序要执行的命令中放入“ sudo”，所以我将其放入。而且没有用。

我认为它不起作用，因为启动器执行了sudo /opt/netbeans/bin/netbeans，但是没有输入密码。经过一番研究，我最终在star_man ALL=(ALL) NOPASSWD: /opt/netbeans/bin/netbeans的末尾添加了/etc/sudoers，终于可以了。但是当我创建一个新项目时，Netbeans将root设置为它创建的每个文件的作者。

例如，当我在项目目录中键入ls -l时，将输出以下内容：

-rw-r--r-- 1 root root 3527 sep 15 20:01 build.xml
-rw-r--r-- 1 root root   82 sep 15 20:01 manifest.mf
drwxr-xr-x 3 root root 4096 sep 15 20:01 nbproject
drwxr-xr-x 3 root root 4096 sep 15 20:01 src

根是组，每个文件的所有者是目录。

这导致Netbeans生成文档文件时，将“ root”代替我的用户名。

更新：我只能以根用户身份启动neatbeans（sudo ./netbeans）。

当我在终端上没有sudo的情况下运行neatbean时，它看起来像是在开始：screen shot

但随后关闭。

这是输出：

我发现~/.netbeans下的每个文件和目录都具有root作为所有者和组。我以为可能是问题所在，所以我用~/.netbeans $ sudo chown -R myusername: .netbeans/更改了所有者和群组。而且我仍然只能以root身份运行netbeans。

Answer 1

这是一个基本的Unix权限问题。

出于逃避我的原因，您使用sudo启动了netbeans IDE。
-你不应该那样做的。
-您不必需要来做到这一点！

使用sudo运行某些程序时，通常以root用户身份运行。（sudo就是这样做的！）

因此，自然地，某些东西（在这种情况下，使用netbeans运行的sudo应用程序）将创建“ root”用户拥有的文件和目录。因此，当您尝试以普通用户身份对其进行更新时，操作系统会显示“不，您不拥有这些文件/目录，因此无法对其进行修改。”

解决方案：使用chown命令根据需要更改文件和目录的所有权。

如何？阅读man chown，或寻找有关如何更改文件所有权的教程。

提示：进行加...时，您将需要使用sudo
提示2：使用sudo时要非常小心，因为如果发生错误，sudo会破坏系统。

Netbeans将root设置为作者
