适用于Python3的OSX HIDAPI安装(pip3故障排除):High-Sierra

本文介绍了适用于Python3的OSX HIDAPI安装(pip3故障排除):High-Sierra的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

OSX High-Sierra:已成功为python 2.7安装HIDAPI.今天已安装Python3:

OSX High-Sierra: HIDAPI was successfully installed for python 2.7. Python3 was installed today:

Users-MacBook-Air:~ user$ python3 --version
Python 3.7.5

在 python3安装后重新安装了HIDAPI:

HIDAPI was reinstalled after the python3 installation:

brew reinstall hidapi

此操作恢复了与python2一起使用的python脚本，并恢复了与条形码扫描仪脚本一起使用的

This restored the python script that was working with python2 and restored the barcode scanner script is working with:

sudo python2 test5.py

但是尝试使用python3运行脚本会返回错误:

However attempts to run the script with python3 returns an error:

sudo python3 test5.py

ModuleNotFoundError: No module named 'hid'

尝试通过pip3为python3 安装HIDAPI 失败:

An attempt install HIDAPI for python3 via pip3 failed:

pip3 install hidapi

是否有必要并且有可能使用PIP3为python3 安装HIDAPI ?

Is it necessary and possible to install HIDAPI with PIP3 for python3?

感谢您克服pip3错误的建议:谢谢

Suggestions to overcome pip3 errors are appeciated: thank you

sudo -H pip3 install hidapi返回:

推荐答案

https://github.com/trezor/cython-hidapi/issues/65 这似乎是软件中的错误.

https://github.com/trezor/cython-hidapi/issues/65 This seems to be bug in the software.

纠正措施

从以下位置安装 Xcode 10.1(与Sierra兼容) Apple网站确保将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应该使用

CORRECTIVE ACTION

Install Xcode 10.1 (High-Sierra Compatible) from the Apple website Be sure to install Xcode to /Applications directory. If it is not installed to /Applications move it from /Downloads to /Applications. The path xcode-select -p should be corrected using

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/

命令:

/usr/bin/xcodebuild -version

应返回:

Xcode 10.1
Build version 10B61
