一、二維碼識別模塊 pyzbar報錯
1.1 模塊安裝報錯
參考：https://blog.csdn.net/pythonlaodi/article/details/112783132
項目識別二維碼需要安裝pyzbar,安裝完，啟動項目出現如下報錯！FileNotFoundError: Could not find module '你的路徑\Python\Python38\site-packages\pyzbar\libzbar-64.dll' (or one of its dependencies). Try using the full path with constructor syntax
解決方法：
-
沒事，這個坑我已經踩過。這個報錯的原因是沒有安裝
Visual C++的依賴庫 -

進入之后，拉到下面可以看到下載的按鈕，下載完之后安裝即可！：
1.2 pyinstaller打包后 Failed to load dynlib/dll 'libiconv.dll'
項目在沒打包前運行沒問題，識別正常，打包后就有以下報錯，這是因為該模塊的dll加載失敗造成的
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 <listcomp> 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'.

解決方法：
第一種方法：在自己的虛擬環境中找到該模塊的dll,手動復制粘貼到打包后目錄即可：
第二種方法：修改spec文件的時候設置好導入位置，打包時會自動識別
二、某些模塊無法用pipenv安裝，或者安裝后可以使用，打包后出錯
詳見以下文章第五步：
pyinstaller打包完整python項目 pyinstaller如何給打包后的文件添加文件版本信息
三、打包后無法正常運行，閃退
我遇到這個情況，不打包運行的好好的，打包后一運行就閃退，
不要用雙擊模式運行，可以用cmd或者powershell運行exe，這樣閃退后打印出報錯信息
報錯缺少模塊，這種情況很可能是沒有在虛擬環境內部進行打包，詳見以下文章描述，嚴格執行打包流程再來一次可能就好了

四 pipenv graph 執行報錯 IndexError: list index out of range pipenv安裝模塊出錯
