pyinstaller打包项目报错总结（很重要:pyinstaller 打包总结）

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 File "pyzbar\zbar_library.py", line 50, in load_objects File "pyzbar\zbar_library.py", line 51, in File "ctypes\__init__.py", line 447, in LoadLibrary File "PyInstaller\loader\pyimod04_ctypes.py", line 56, in __init__pyimod04_ctypes.PyInstallerImportError: Failed to load dynlib/dll 'libiconv.dll'.

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

四 pipenv graph 执行报错 IndexError: list index out of range pipenv安装模块出错
