CYB3RMX commented 3 years ago

I installed dexcalibur on ParrotOS via npm command. After the installation I tried to execute the program with dexcalibur command and program threws errors. Error message:

internal/fs/utils.js:269
    throw err;
    ^

}

How can I fix this error?

Hey, with some distribution this error happens because /home/user/.dexcalibur folder has not good permissions (some distribution require 'execute' attr even for a simple write) => NPM does not set right permissions at install

Can you try chmod 777 /home/user/.dexcaliburand dexcalibur --reinstall ?

I created .dexcalibur folder manually then I executed commands. But now program hangs here:

Server started on : 8000
[Object: null prototype] { _t: '1616022167300' }
Execute command request : java -jar /usr/local/lib/node_modules/dexcalibur/bin/baksmali.jar d /home/user/dexcaliburWS/.dxc/tmp/sdk_androidapi_29_google.dex -o /home/user/dexcaliburWS/.dxc/api/sdk_androidapi_29_google

What should I do now?

FrenchYeti commented 3 years ago

For 'Execute command request', red text is not an error. It just lets you know Dexcalibur executes a command on your computer.

did you open http://127.0.0.1:8000/ ?

CYB3RMX commented 3 years ago

Yes. The installation page says success.

FrenchYeti commented 3 years ago

ok, you can exit (Control+C) process, and rerun dexcalibur
