A simple PDF viewer based on mozilla/pdf.js. The gadget powered by Python Flask and bundled its applications and dependencies into a single executable package for Windows.

The pdfviewer is in order to work with the talentranslate (a browser extension) for local PDF files translation.

I recommend that you create a virtual environments:

D:\pdfviewer> python -m venv venv

Enter the virtual environments:

D:\pdfviewer> venv\Scripts\activate

These commands above run in the Microsoft Windows command prompt windows (cmd.exe).

(venv) D:\pdfviewer> pip install flask pyinstaller

If you have a terrible download speed, you can use the option -i <mirror for pip>, for instance, in China:

(venv) D:\pdfviewer> pip install flask pyinstaller -i https://pypi.tuna.tsinghua.edu.cn/simple

You have two choices, one is onefile version and one is onedir version.

Onefile version:

(venv) D:\pdfviewer> pyinstaller pdfviewer_onefile.spec

Onedir version:

(venv) D:\pdfviewer> pyinstaller pdfviewer_onedir.spec
