错误:无法为使用 PEP 517 且无法直接安装的 bcrypt 构建轮子 [英] ERROR: Could not build wheels for bcrypt which use PEP 517 and cannot be installed directly

问题描述

pycharm 中的解释器配置由于某种原因变得无效，所以我为我正在处理的项目创建了一个新的虚拟环境，并再次安装了依赖项.但是我在再次安装 bcrypt 时遇到了麻烦.这是完整的错误.该项目在以前的解释器上运行良好，所以我怀疑 python 版本与它有什么关系.我尝试安装轮子以及错误说 could not buildwheels 但这也没有完成这项工作.

The interpreter configuration in pycharm became invalid for some reason so I created a new virtual environment for the project that I was working on, and installed the dependencies again. But I am having trouble in installing bcrypt again. Here's the complete error. The project was working fine with the previous interpreter so I doubt that the python version has anything to do with it. I tried installing wheel as well as the error said could not build wheels but that didn't do the job as well.

推荐答案

尝试使用这些命令:

python -m pip install --upgrade pip
python -m pip install --no-use-pep517 bcrypt
