最近在玩seeed的一个板子，其中教程中有一个命令：pip install ./snowboy*.whl，但是我输入后就报错了，给大家看看错误提示，希望大佬可以解答一下；（在python的虚拟环境下运行）

打算用树莓派开发，板做一个小项目。买到的开发板除了芯片资料就没有其他了，网上的资源也相对比较少。我想提问的是，当拿到一个开发板，该如何从头开发一个项目？（其实也算不上开发，只是把其他板上原有的项目搬过来新板子罢了。）能大概说一下项目开发具体流程还有过程中要注意的点吗？
参考这个设置的，但是反向的，把“SwapAxes”和“InvertY”的两个参数改为0也不行？什么原因？Section "InputClass" Identifier "captouch" MatchProduct "ft6x06_ts" Option "SwapAxes" "1" Option "InvertY" "1" Option "Calibration" "0 320 0 240"EndSection
编译vscode源码时提示好几个node的库不存在，全部down下来之后还是无法正常编译，有谁编译成功过吗？
这一类Linux开发板的GPIO引脚驱动能力强吗？电流能达到多少？够驱动步进电动机吗？
请问树莓派3在安装Arch时。到了解压包的那一个步骤了，用的是bsdtar ，出现[root@localhost ARCH]# bsdtar -xpf ArchLinuxARM-rpi-3-latest.tar.gz -C rootbsdtar: could not chdir to 'root'请问各位如何解决这个问题，另外我是过直接用tar解压，但是好像没什么用。我真的很想安装Arch Linux阿!
新人求教，在树莓派中用python编程，如何连接树莓派外部的数据库，求详细的操作流程，谢谢各位大神。
