pipreqs ./ --encoding=utf-8 --force 报错问题解决_Python

报的编码问题，其实不是：

解决方法:

pipreqs --ignore .venv --force

--ignore: 忽略执行

--force : 强制覆盖requirements.txt的内容

解决过程

1.执行命令：

pipreqs ./ --encoding=utf-8 --force

2.报错如下：

3.再次执行命令：

 pipreqs ./ --encoding=iso-8859-1 --force

4.再次报错如下：

5.解决方法：

虚拟环境依赖问题忽略.venv：执行成功

pipreqs --ignore .venv --force
