Python packs into an EXE file First, you need to install the Pyinstaller library, then enter the target file directory, enter the command line package PY file, but an error occurred:TypeError: an integer is required (got type bytes) . My python3.9, the following is the process of problem-solving problems:

1. Install the Pyinstaller library

Open WIN + R, enter the CMD to enter the terminal Terminal. Terminal input commandpip install pyinstaller Install the library, after installationpip list Displays the Pyinstallers version 3.3.1.

pip install pyinstaller

2. Pack PY file

2.1 Pyinstaller command parameters

First, you need to know the parameters of the pyinstaller command, such as:

pyinstaller -F -w -i demo.ico test.py

Pyinstaller parameters (common parts)

parameter	meaning	Detailed description
-i	Icon path	Need pictures for ICO format, you can convert pictures such as PNG to ICO images with online format conversion tools.
-F	Pack a single exe file	There is only one PY file through the code. If there are multiple PY files, don't choose this parameter.
-D	Package multiple files	Create a directory, DIST contains EXE and many dependencies, code to be written in the framework
-w	Prohibition of command line windows	When you start an Exe program, you will not pop up the command line window (which is only valid for Windows)
-c	Use console	Run using the console subsystem (only valid for Windows)
-h	View help

It means packing the Test.py file into a single exe file, and generates an EXE icon with the root directory image Demo.ico, and the command line pop-up window is prohibited when runs the exe file.

2.2 Pack PY into an EXE file

Then enter the target file directory (I am E: \ Test \ Tree.py), execute the package commandpyinstaller -F xx.py

E: # Switch the catalog to the E disk
 CD Test # Enter the target folder
 Pyinstaller -f tree.py # Treume file Tree.py single exe file package

But an error occurred:TypeError: an integer is required (got type bytes), Packages fail. Successful sign is a tail line display completed successfully At the same time, some files are generated in the Tree.py root directory, where there is an Exe file under the Dist folder, you can run separately in any place (such as other computers).

3. Find the reason for the error

3.1 Replace the installation of Pyinstaller

Although installationpyinstaller Successful, but the installation process still has some bursts, use other methods to replace the installation of Pyinstaller, execute the command:

 pip install https://github.com/pyinstaller/pyinstaller/archive/develop.tar.gz

But I didn't expect to report any error:SyntaxError：Command errored out with exit status 1：

3.2 View error content

Carefully check the middle of an error message:

SyntaxError：（unicode error）'utf-8' codec can't decode byte 0xbe in position 0: invalid start byte
Error：Building wheels requires the 'wheel' package. Please 'pip install wheel' then try again

The first line of SyntaxError said that the encoding error is unable to decode the UTF-8 format. The net checks some information indicates that the default is GBK encoding. You need to download the original file to modify the source code, increase Encoding = 'UTF-8', trouble;

The second line error said that the WHEEL module is missing, you can install the Wheel and try. Decide to select this method:

pip install wheel

When you install the WHEEL module, you can see that the system automatically unresses the installed Pyinstaller version 3.3.1, throughpip listView replacement with a 5.0.dev0 version.

3.3 Note that the EXE icon should be .ico format

Now I can try the PY file, because I want to customize the icon logo, I downloaded an icon's PNG format file from the Alibaba Vector Icon library, directly refix the suffix .ico file, execute the command:

pyinstaller -F -i tree.ico tree.py

But once again report:struct.error: unpack requires a buffer of 16 bytes

The query learned that the icon in the PNG format must be converted to .ICO format, cannot be forced to change the suffix, so the online conversion tool converts the icon into a .ico format. Run the command again:pyinstaller -F -w -i tree.ico tree.py Success!

pyinstaller -F -w -i tree.ico tree.py 

4. Final effect

Tree.Py Starting Directory:

The directory after packaging the exe file automatically generates a lot of files:

EXE file is in the Dist folder:

Double click to run Tree.exe to see the effect:

Try running Tree.exe with other computers, everything is normal. awesome!
