Question

我按照本页上的说明操作：
http://python.dronekit.io/guide/quick_start.html

我做了什么：

pip install dronekit

pip install dronekit-sitl

然后我用它创建了一个python文件：

print ("Start simulator (SITL)")
import dronekit_sitl

sitl = dronekit_sitl.start_default()
#connection_string = sitl.connection_string()

# Import DroneKit-Python
from dronekit import connect, VehicleMode

# Connect to the Vehicle.
print("Connecting to vehicle on: %s" % ('tcp:127.0.0.1:5760',))
vehicle = connect('tcp:127.0.0.1:5760', wait_ready=True)

# Get some vehicle attributes (state)
print ("Get some vehicle attribute values:")
print (" GPS: %s" % vehicle.gps_0)
print (" Battery: %s" % vehicle.battery)
print (" Last Heartbeat: %s" % vehicle.last_heartbeat)
print (" Is Armable?: %s" % vehicle.is_armable)
print (" System status: %s" % vehicle.system_status.state)
print (" Mode: %s" % vehicle.mode.name)    # settable

# Close vehicle object before exiting script
vehicle.close()

# Shut down simulator
sitl.stop()
print("Completed")

然后我跑了，这是我在终端上得到的错误：

olin30259168:Desktop physics$ python hello.py

我应该得到的是：

它似乎连接，但它超时尝试校准气压计，当我运行从此目录克隆的示例时，我遇到了同样的问题：

Answer 1

这是我在Windows 10上安装的，如果它给出同样的问题，只需重新启动计算机并重新运行它最多4次然后让我知道。

1）安装Python 2.7

2）转到https://pip.pypa.io/en/stable/installing/ 一个。点击get-pip.py 湾将其保存在桌面上 C。下载后双击它

3）转到命令提示符一个。如果它说C：\ Users \ oscar4423＆gt; 一世。键入cd C：\ Python27 \ Scripts 湾一旦完成步骤，就像这样输入pip：C：\ Python27 \ Scripts＆gt; pip C。现在输入pip安装请求：C：\ Python27 \ Scripts＆gt; pip install requests

4）关闭命令提示符

5）转到https://git-scm.com/downloads，然后点击“下载适用于Windows”

6）安装git 7）打开命令提示符并键入cd C：\ Python27 \ Scripts

8）输入pip install git + https://github.com/3drobotics/solo-cli C：\ Python27 \ Scripts＆gt; pip install git + https://github.com/3drobotics/solo-cli

9）现在安装以下pip install virtualenv 10）在命令提示符下键入pip install dronekit，如下所示： C：\ Python27 \脚本＆GT; pip install dronekit

11）在命令提示符下键入pip install dronekit-sitl，如下所示： C：\ Python27 \脚本＆GT; pip install dronekit-sitl

12）pip install numpy pyparsing

13）pip install MAVProxy

除了dronekit和dronekit stil之外还需要安装什么来运行快速启动页面上的hello.py程序吗？
