【PyQt】使用 pyinstaller 构建 exe

首先可能需要安装一下 PyInstaller：

pip install pyinstaller

PyInstaller 的官方文档：PyInstaller Manual
构建命令：

pyinstaller [opt] [要打包的程序.py]

可选的 opt 有：

-D, -–onedir 创建一个目录，包含exe文件，但会依赖很多文件（默认选项）。
-F, -–onefile 打包成一个exe文件。
-c, –console, –nowindowed 使用控制台，无界面(默认)
-w, -–windowed, –noconsole 使用窗口，无控制台

构建过程中得到的 WARNING 及解决方法：

ctypes imports are only supported using bare filenames
去掉引用 DLL 前面的路径或是 ./
lib not found: mfc90.dll dependency of 路径\ControlCAN.dll
lib not found: MSVCR90.dll dependency of 路径\ControlCAN.dll

One binary added with two internal names.

有人说是编码的问题，改成 GBK 试试……然而依旧不行

换自己的笔记本上打包，更不得了了……可能公司电脑什么乱七八糟的都装上了，所以对于依赖项感受不到，这换到新环境，问题一下子就暴露出来了

打包完，到 dist 文件夹里找 main.exe 打开运行，果然显示 Failed to execute script main

然后就发现 ControlCAN.dll 依赖于 Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package MFC 安全更新（至于可能遇到缺失其他的依赖库的情况，可以到这里去找：https://support.microsoft.com/zh-cn/help/2977003/the-latest-supported-visual-c-downloads）

然后至于上面那些 lib not found: api-ms-win-crt-啥啥啥 的警告，原来缺失的相关库文件路径在这里：C:\Windows\System32\downlevel
解决这个问题的方法：

pyinstaller -p C:\Windows\System32\downlevel xxx（xxx：你要打包的项目）
或者是直接跑到这个目录下，把里面所有的 dll 文件全复制过来

至于 Hidden import "sip" not found! 的警告，貌似这个包没啥用，可以用以下方法屏蔽掉：
pyinstaller -p C:\Windows\System32\downlevel -Fw main.py --hidden-import=PyQt5.sip

【PyQt】使用 pyinstaller 构建 exe
