    @sdetweil I understand that some authors do not use the current libs. The “strange” referred to the fact that I have no problems with MMM-DWD-WarnWeather, but others have to install the module “request”.

    Open source is both a curse and a blessing. Now everything works again and MM’s layout changes to the clock module were also quickly undone. :slightly_smiling_face:

      did u npm install request in the mm folder, or in a module folder where there was no package.json, the latter ends up putting it in the mm/node_modules, the same as the former

        Maybe this can help some users.

        The following will search all *.js files in the modules folder for the reference of request. You can then just enter the module folders and install as per @sdetweil suggestion above. The same can be done for the other missing modules.

        grep -r -E '('request')' ~/MagicMirror/modules/*/*.js
        

        or search for multiple problem modules

        grep -r -E '('request') | ('valid-url')' ~/MagicMirror/modules/*/*.js
        

        Produces the following:

          @mumblebaj and then pull off the module name and scan it’s package.json to see if it’s referenced

            I installed it the way you suggested. In the two module folders with the addition of package.json (npm init -y) and then npm install request. The MMM-DWD-WarnWeather worked on my mirror from the beginning after updating to MM2.17.

              I enhanced my upgrade script to do all this for all installed modules…

                @sdetweil @mumblebaj Thank you two for helping me solve this problem after the last update - I spent a LOT of time looking for the solution that you two helped me (the grep made it easier to find the right modules), the two commands were what fixed it.

                Will I have to do this again with the next update?

                    @sdetweil Thanks … I will give this a try next time I’m updating. I thought I had tried it before, but perhaps not. I appreciate you sharing this.
