（1）下载tar包。打开终端，输入：wget https://download.sublimetext.com/sublime_text_3_build_3176_x64.tar.bz2

（2）解压：tar -xvf sublime_text_3_build_3176_x64.tar.bz2

（3）输入：sudo su，将sublime_text_3移动到/opt/这个目录下，这个目录是放软件的。输入：mv sublime_text_3 /opt/

（4）cd 进入sublime_text_3的文件夹，运行 ./sublime_text 即可打开sublime text 3

（5）创建快捷方式，继续输入：cp /opt/sublime_text_3/sublime_text.desktop /usr/share/applications

解决无法输入中文的问题

首先保证系统已经安装好了搜狗输入法,搜狗输入法在 linux下的安装教程：

（6）在home目录下新建sublime-imfix.c文件，在文件中输入以下代码：

/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang <jianzhong.huang at i-soft.com.cn>
gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so sublime_text
*/
#include <gtk/gtk.h>
#include <gdk/gdkx.h>
typedef GdkSegment GdkRegionBox;

struct _GdkRegion
{
  long size;
  long numRects;
  GdkRegionBox *rects;
  GdkRegionBox extents;
};

GtkIMContext *local_context;

void
gdk_region_get_clipbox (const GdkRegion *region,
            GdkRectangle    *rectangle)
{
  g_return_if_fail (region != NULL);
  g_return_if_fail (rectangle != NULL);

  rectangle->x = region->extents.x1;
  rectangle->y = region->extents.y1;
  rectangle->width = region->extents.x2 - region->extents.x1;
  rectangle->height = region->extents.y2 - region->extents.y1;
  GdkRectangle rect;
  rect.x = rectangle->x;
  rect.y = rectangle->y;
  rect.width = 0;
  rect.height = rectangle->height; 
  //The caret width is 2; 
  //Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
  if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
        gtk_im_context_set_cursor_location(local_context, rectangle);
  }
}

//this is needed, for example, if you input something in file dialog and return back the edit area
//context will lost, so here we set it again.

static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)
{
    XEvent *xev = (XEvent *)xevent;
    if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {
       GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window");
       if(GDK_IS_WINDOW(win))
         gtk_im_context_set_client_window(im_context, win);
    }
    return GDK_FILTER_CONTINUE;
}

void gtk_im_context_set_client_window (GtkIMContext *context,
          GdkWindow    *window)
{
  GtkIMContextClass *klass;
  g_return_if_fail (GTK_IS_IM_CONTEXT (context));
  klass = GTK_IM_CONTEXT_GET_CLASS (context);
  if (klass->set_client_window)
    klass->set_client_window (context, window);

  if(!GDK_IS_WINDOW (window))
    return;
  g_object_set_data(G_OBJECT(context),"window",window);
  int width = gdk_window_get_width(window);
  int height = gdk_window_get_height(window);
  if(width != 0 && height !=0) {
    gtk_im_context_focus_in(context);
    local_context = context;
  }
  gdk_window_add_filter (window, event_filter, context); 
}

（7）通过以下命令安装C\C++编译环境和gtk libgtk2.0-dev：

sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev

（8）执行以下命令编译共享库。执行该命令时需要在sublime-imfix.c文件所在的目录。

cd /home/y430/

gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

（9）将libsublime-imfix.so拷贝到sublime_text所在文件夹(我的是sublime_text_3，你需要在下列代码中做相应修改)

sudo mv libsublime-imfix.so /opt/sublime_text_3/

（10）修改文件/usr/bin/subl的内容，如果subl文件不存在，则自行创建，创建完成后将上述要修改成的代码复制粘贴进去即可。

sudo gedit /usr/bin/subl

将

#!/bin/sh
exec /opt/sublime_text_3/sublime_text "$@"

修改为

#!/bin/sh
LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so exec /opt/sublime_text_3/sublime_text "$@"

然后进入/usr/bin 目录下赋予 subl 文件可执行的权限：

cd /usr/bin
sudo chmod +x subl

最后执行命令：subl， 命令执行完成后，sublime text 3 会自动弹出并且已经支持中文的输入了！

（11）为了使用鼠标右键打开文件时能够使用中文输入，还需要修改文件sublime_text.desktop的内容。

sudo gedit /usr/share/applications/sublime_text.desktop

将[Desktop Entry]中的字符串

Exec=/opt/sublime_text/sublime_text %F

修改为

Exec=bash -c "LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so exec /opt/sublime_text_3/sublime_text %F"

将[Desktop Action Window]中的字符串

Exec=/opt/sublime_text/sublime_text -n

修改为

Exec=bash -c "LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so exec /opt/sublime_text_3/sublime_text -n"

将[Desktop Action Document]中的字符串

Exec=/opt/sublime_text/sublime_text --command new_file

修改为

Exec=bash -c "LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so exec /opt/sublime_text_3/sublime_text --command new_file"

注意：

修改时请注意双引号"",否则会导致不能打开带有空格文件名的文件。

（12）重启系统，输入：

subl

即可在Sublime中使用中文。
