electron-rebuild problems with MagicMirror 2.22.0

 @wishmaster270 said in electron-rebuild problems with MagicMirror 2.22.0: and the postinstall script will work as excepted. yes, will work, but all the changes in the node_modulesfolder of mm are gone with the next restart of the container …

 @karsten13 
 In case of electron-rebuild this is no problem as it is only required during compile but not at runtime.
- 
 o.k., but where are the compile results stored? 
- 
 @karsten13 
 They are stored in thenode_modulesfolder of the module which should be persistentEdit: Do not misunderstand me. In my opinion the best way to solve the electron-rebuild problems of a lot of modules would be to put “@electron/rebuild” as a dependency to “package.json” of MagicMirror.

 They are stored in thenode_modulesfolder of the module which should be persistentthats good, so the construction with installing electron-rebuildin mm folder has no side effects and works also in a docker setup.

I don’t have a final opinion on that yet, but if so, we should put it under optionalDependenciesaselectron

 You are right. I think optionalDependencieswould be a great solution. Module developers could then add a hint to runnpm ciin the MagicMirror directory to their installations instructions.As the container it self is untouched it should be no problem. It only causes @electron/rebuild to be installed the next time the script is called. 
- 
 @KristjanESPERANTO but if u look at electron/rebuild after install u call electron-rebuild still has to be installed in the base node_modules folder… older unmaintained modules are broken either way. why I had to fork MMM-Buttons. 
- 
 @wishmaster270 optional is there so that IF electron is NOT installed, the install does not fail (needed on pi0w at least) 
 have nothing to do w cimy script ONLY installs prod, no dev. as 99.5% of users are users not mm developers. has nothing to do w module developers 
- 
 @karsten13 and the postinstall checks for it being there, and if so skips the e-r install. doesn’t know/care HOW it got installed before
