安装飞跃运动猎户座的问题

Question

所以我在安装 Leap Motion Orion 时遇到了一些问题。我正在尝试按如下方式安装它：

cd Downloads/
cd Leap_Motion_Installer_Packages_release_public_linux/
sudo dpkg --install Leap-2.3.1+31549-x64.deb 

错误信息：

dpkg --install Leap-2.3.1+31549-x64.deb

Leap 仍然是为 upstart 设置的，最近从 upstart 迁移到 systemd 使得一些像 Leap 这样的软件包安装失败。

请按照以下步骤操作：

sudo nano /lib/systemd/system/leapd.service
sudo ln -s /lib/systemd/system/leapd.service /etc/systemd/system/leapd.service
sudo systemctl daemon-reload
sudo dpkg --install Leap-2.3.1+31549-x64.deb

跳跃.服务文件：

[Unit]
Description=LeapMotion Daemon
After=syslog.target

[Service]
Type=simple
ExecStart=/usr/sbin/leapd

[Install]
WantedBy=multi-user.target

安装后可以看到：

Check Leap Motion daemon with: service leapd status 
Open the Leap Motion GUI with: LeapControlPanel 
See /usr/share/Leap/README.linux for more information
