I recently downloaded the xlsxwriter version 0.6.4 and installed it on my computer. It correctly added it to my C:\\Python27\\Lib\\site-packages\\xlsxwri
xlsxwriter version 0.6.4
C:\\Python27\\Lib\\site-packages\\xlsxwri
I am not sure what caused this but it went all well once I changed the path name from Lib into lib and I was finally able to make it work.
Lib
lib
