1、正常情況下，我們是通過pip3來安裝PyInstaller，但是在樹莓派的ubuntu20.04上安裝時，會報錯如下：

2、通過錯誤提示，我們可以分析出來，這裏報的錯誤爲Werror，即在用gcc編譯時，將警告信息當作錯誤來處理，並不是真的時運行不下去，所以，我們要做的就是修改makefile，讓使用gcc編譯的時候，不進行Werror處理；
3、我們從pip官網下載pyinstaller源碼
https://pypi.org/project/PyInstaller/
4、將源碼解壓，打開，嘗試直接運行python3 setup.py install ，依舊會報上面的錯誤，現在重點來了，修改make文件，這裏這個make文件也找到了好半天才找到
//進入pyinstaller源碼下面的bootloader文件夾
cd bootloader
//編輯make文件，這裏是wscript
vim wscript
//通過/Werror查找，我們可以找到在第461，gcc的參數裏面有Werror這個參數，直接刪除這一行參數就行，注意只刪除‘-Werror’這一句
//保存退出，返回pyinstaller的根目錄
//安裝就可以了
python3 setup.py install
OK，至此pyinstaller就安裝完成了，可以使用他來發布你的QT程序了
