thank you for your patience. As you said I do the following:
a.) I install nodejs on my PC
b.) I make a local WordPress-installation
c.) I download the Plugin from github (again), install and activate it
And now the following thinks happened:
1.) When I try your Example-Blocks on my local WordPress-installation, the only working Block is the “Static Block”. The other Blocks show following error “This block has encountered an error and cannot be previewed.”
2.) On Atom I open the Plugin-Folder (the folder with the package.json in it) and try “npm install”. Than I get the following code:
PS C:\Wordpress\apps\wordpress\htdocs\wp-content\plugins\jsforwp-example-blocks> npm install npm WARN email@example.com No description npm WARN firstname.lastname@example.org No repository field. up to date in 1.098s PS C:\Wordpress\apps\wordpress\htdocs\wp-content\plugins\jsforwp-example-blocks>
Because of the missing description and repository field in the package.json , I add these fields manually.
After this I try “npm run dev” and get the following errors:
email@example.com dev C:\Wordpress\apps\wordpress\htdocs\wp-content\plugins\jsforwp-example-blocks > cross-env BABEL_ENV=default webpack --watch Der Befehl "cross-env" ist entweder falsch geschrieben oder konnte nicht gefunden werden. (The command "cross-env" is not written correctly or couldn´t be found.) npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! firstname.lastname@example.org dev: <code>cross-env BABEL_ENV=default webpack --watch</code> npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the email@example.com dev script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above. npm WARN Local package.json exists, but node_modules missing, did you mean to install?
Thanks for your help.
