i've tried to work koolreport on linux enviroment but it didn't work at all what should i do???

thx, i got it working on linux, no problem except export it says "Could not execute phantomjs in /var/www/html/koolreport/koolreport/export/Handler.php:68" i've downloaded the phantomjs linux and put it in folder /var/www/html/koolreport/koolreport/export/bin, made permission 777 for all Koolreport folder and my report folder N.B i'm working on raspberry pi as web server

the permission is set to 777 or 755 no difference, here is the typical error if can make any sense to you " Fatal error: Uncaught Exception: Could not execute phantomjs in /var/www/html/koolreport/koolreport/export/Handler.php:68 Stack trace: #0 /var/www/html/koolreport/koolreport/export/Handler.php(275): koolreport\export\Handler->runPhantom('/var/www/html/k...', '/tmp/5fe61c440b...', '/tmp/5fe61c440b...', 'eyJmb3JtYXQiOiJ...') #1 /var/www/html/koolreport/sale report/index.php(50): koolreport\export\Handler->pdf(Array) #2 {main} thrown in /var/www/html/koolreport/koolreport/export/Handler.php on line 68"

i've tried working with cloudexport it didn't work too, gave me lot of this error messages: "Warning: file_get_contents(http://192.168.1.59/koolreport/sale%20report/7fbbf5c44b32b33abe39f384f0594337.js): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /var/www/html/koolreport/koolreport/cloudexport/vendor/chromeheadlessio/php-client/src/Exporter.php on line 187 "

i've reviewed forum post #135 same situation but it is not clear what was the solution

dear I've installed phantomjs via apt-get and changed the path to in setting but still can't execute even i run it from terminal,

Dear All i've lost days trying to make this thing works, as it is essential for me and have dead lines so please try to help me in more efficient way ... NOW i have two problems: first of all export to pdf didn't work at all because it can't execute phantomjs, work around i tried to use export to cloud it didn't work too, as it saves tmp files in a folder inside tmp folder and in zip inside the tmp, when it tries to get contents of theses file it fetches the working folder not the tmp folder which only has the zip file please help me to get out of this ASAP

Dear All I'm still having problems with PDF export, both google charts and chartjs export missing charts in pdf though the rest of report is showing well this is the case even with your example as shown in previous posts David regarding cloudexport the js files doesn't exist in this folder it is located inside folders inside tmp folders and inside zip files- please see attached picture, i don't know what makes the program fetching the file in a wrong place kindly try to help me to find a solution or the package will be useless for me
