I want to install package on webOS running time.
But I can't find package manager command like apt-get, dpkg, rpm, npm, pip...
And I saw many official document. They said you must include the package you want before building the webOS.
I used an already builded image. Because my host computer was too slow to 'build images'.
Can I install package after build image? (opencv, gcc ...)
Thanks to read.
