OSX High-Sierra：已成功为python 2.7安装HIDAPI。今天已安装Python3：
Users-MacBook-Air:~ user$ python3 --version
Python 3.7.5
在安装python3之后重新安装了HIDAPI：
brew reinstall hidapi
这恢复了使用python2的python脚本，并恢复了条形码扫描器脚本的使用：
sudo python2 test5.py
但是，尝试使用python3运行脚本会返回错误：
sudo python3 test5.py
ModuleNotFoundError: No module named 'hid'
通过pip3尝试python3 install HIDAPI失败：
pip3 install hidapi
使用PIP3 for python3 install HIDAPI是否必要且可能？
建议克服pip3错误：谢谢
错误讯息：
sudo -H pip3 install hidapi返回：Collecting hidapi

更新
模块：
pip3 install hidapi==0.7.99.post14
指出了几个构建错误，但最终指出：
Installing collected packages: Cython, hidapi
Running setup.py install for hidapi ... done
Successfully installed Cython-0.29.14 hidapi-0.7.99.post14
经过测试和验证的python3处理HID流量。
最佳答案
https://github.com/trezor/cython-hidapi/issues/65这似乎是软件中的错误。
同时，Hacky解决方案是获取与Xcode 10捆绑在一起的MacOSX10.14 SDK。
纠正措施
安装Xcode 10.1 (High-Sierra Compatible) from the Apple website确保将Xcode安装到/ Applications目录。如果未安装到/ Applications，请将其从/ Downloads移至/ Applications。
路径xcode-select -p应使用
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/
命令：
/usr/bin/xcodebuild -version
应该返回：
Xcode 10.1
Build version 10B61
正确使用Xcode以支持pip3：
$ pip3 install hidapi
