powerpoint Error in knit_print.flextable(x, ...) : pandoc version >= 2.4 required for printing flextable in pptx code example

Example 1: edje js not pre compile for node 12 version

Hopefully the error description is clear.
So here what I did when I got this error :
Go to https://github.com/tjanczuk/edge
Download the repository and extract it
Open a terminal and go to the tools folder
run build.bat release 8.9.3
copy the generated files in the edge npm folder
%AppData%\npm\node_modules\vs-tac\node_modules\edge\lib\native\win32\x64
in my case :
concrt140.dll
msvcp140.dll
vccorlib140.dll
the 8.9.3 folder
edit the %AppData%\npm\node_modules\vs-tac\node_modules\edge\lib\edge.js file
Add an entry for your version in the versionMap variable.
var versionMap = [
[ /^0\.8\./, '0.8.22' ],
[ /^0\.10\./, '0.10.0' ],
[ /^0\.12\./, '0.12.0' ],
[ /^4\./, '4.1.1' ],
[ /^5\./, '5.1.0' ],
[ /^6\./, '6.11.3' ],
[ /^8\./, '8.9.3' ] ];
Enjoy !
