在使用pyzbar模块进行二维码识别时，遇到1.1版本安装问题。解决步骤如下：
1. 确认已正确安装pyzbar模块。
2.尝试重新安装pyzbar，使用以下命令：
pip install pyzbar==1.13.安装完成后，启动项目，若出现`FileNotFoundError: Could not find module '你的路径\Python\Python38\site-packages'`错误，请检查以下原因：
- Python环境路径设置不正确。 - 项目运行时未正确引用pyzbar模块。解决方法：
1.确保Python环境路径正确。
2.检查项目代码中pyzbar模块的引用路径是否正确。
一、二维码识别模块 pyzbar报错
1.1 模块安装报错
项目识别二维码需要安装pyzbar,安装完，启动项目出现如下报错！
FileNotFoundError: Could not find module '你的路径\Python\Python38\site-packages\pyzbar\libzbar-64.dll' (or one of its dependencies). Try using the full path with constructor syntax
解决方法：
- 没事，这个坑我已经踩过。这个报错的原因是没有安装Visual C++的依赖库
- 下载地址：Visual C++ Redistributable Packages for Visual Studio 2013
- 进入之后，拉到下面可以看到下载的按钮，下载完之后安装即可！：
1.2 pyinstaller打包后Failed to load dynlib/dll 'libiconv.dll'
项目在没打包前运行没问题，识别正常，打包后就有以下报错，这是因为该模块的dll加载失败造成的
Traceback (most recent call last):File "pyzbar\zbar_library.py", line 58, in load

解决方法：
第一种方法：在自己的虚拟环境中找到该模块的dll,手动复制粘贴到打包后目录即可：
第二种方法：修改spec文件的时候设置好导入位置，打包时会自动识别
二、某些模块无法用pipenv安装，或者安装后可以使用，打包后出错
详见以下文章第五步：

三、打包后无法正常运行，闪退
我遇到这个情况，不打包运行的好好的，打包后一运行就闪退，
不要用双击模式运行，可以用cmd或者powershell运行exe，这样闪退后打印出报错信息
报错缺少模块，这种情况很可能是没有在虚拟环境内部进行打包，详见以下文章描述，严格执行打包流程再来一次可能就好了
