Hi there, I decided to start with a fresh installation of the angular frontend. I have following version installed: npm version: 9.6.6 yarn version: 1.22.19 node version: v16.20.0
execpt for a new config.prod.yml in the config directory, with the minimal configuration as stated in the install guide, nothing changed in the dspace-angular code checked out from git with tag dspace-7.5 If I do *yarn install* I get warnings: yarn install v1.22.19 [1/4] Resolving packages... [2/4] Fetching packages... [3/4] Linking dependencies... warning " > bootstrap@4.6.2" has unmet peer dependency "jquery@1.9.1 - 3". warning " > bootstrap@4.6.2" has unmet peer dependency "popper.js@^1.16.1". warning " > ngx-sortablejs@11.1.0" has incorrect peer dependency "@angular/common@^11.0.0". warning " > ngx-sortablejs@11.1.0" has incorrect peer dependency "@angular/core@^11.0.0". [4/4] Building fresh packages... Done in 124.82s. Might this be the reason, why it is not working for me. How can I fix this. I am new to angular, node,js, yarn & co Kind regards Christiane Christiane Baier schrieb am Donnerstag, 11.
