||
| ## Package app | ||
|
|
||
| This is an example of using [PyInstaller](http://www.pyinstaller.org/) | ||
| packager to build executable from one of CEF Python's examples | ||
| (wxpython.py). Only Windows platform is currently supported. | ||
|
|
||
| To install required packages type: | ||
| ``` | ||
| pip install --upgrade pyinstaller pycrypto | ||
| ``` | ||
|
|
||
| To package example type: | ||
| ``` | ||
| python pyinstaller.py | ||
| ``` | ||
|
|
||
|
|
||
| ## When it succeeds | ||
|
|
||
| If packaging succeeds you should see "dist/cefapp/" directory open | ||
| in explorer on Windows. In there you will find "cefapp.exe" executable | ||
| that you can launch. | ||
|
|
||
|  | ||
|
|
||
|
|
||
| ## Fatal error | ||
|
|
||
| If there is a "Fatal Error!" message box appearing when running app | ||
| then see the next section for how to debug app. | ||
|
|
||
|  | ||
|
|
||
|
|
||
| ## Debug app | ||
|
|
||
| In case of a fatal error to debug app pass "--debug" flag when | ||
| packaging app: | ||
|
|
||
| ``` | ||
| python pyinstaller.py --debug | ||
| ``` | ||
|
|
||
| After packaging completes on Windows it will open a new CMD window | ||
| and run the cefapp.exe inside it. You should see detailed logs | ||
| in console like these: | ||
|
|
||
| ``` | ||

I tried many times and found that using pyinstaller 3.4 may cause problem and failed to build exe, while using pyinstaller 3.3 will be OK.
