How to MANUALLY install MM on your Pi. For absolute beginners.

I’m going to walk you through this. Why? Well, someone always helped me when I was new.
What better way to repay them? By helping others, that’s how.

Raspbian is already installed?

This tutorial assumes that you’ve already set up your Pi correctly

Why a manual install?

The automatic installation script failed or did not complete
You upgraded from an earlier version of MM and now your mirror doesn’t work
Troubleshooting often takes longer than this
You want to learn a new or different way to install MM
You always listen to my suggestions

You won’t lose your current installation

You’ll be renaming your current MM folder so nothing will be lost

Let’s get to it

Rename your current MagicMirror folder. (e.g MagicMirror-OLD)
Go to https://github.com/MichMich/MagicMirror in your browser
Click on the green Clone or Download button on the right side of the window
Click on Download ZIP. Now you have a MagicMirror-master.zip file
Double Click the MagicMirror-master.zip file. Inside is the MagicMirror-master folder.
Move the MagicMirror-master folder to your /home/pi folder. (Where your MagicMirror-OLD is)
Rename the MagicMirror-master folder to MagicMirror.
Then in your terminal, cd into the MagicMirror directory and run npm install.
When that finishes, run npm start, also in the MagicMirror directory.
At this point the mirror should run but you’ll likely get a “Create a config” message.

Don’t worry, you’re almost there

Create a working config. If you don’t know how you should go to the following link.

https://forum.magicmirror.builders/topic/4528/how-to-create-a-working-config-for-absolute-beginners

Once you’ve created a working config, open your terminal
cd into the MagicMirror directory and run npm start. That should get your mirror running.
Then you can copy your modules, 1 by 1, into the new MagicMirror/modules folder
Copy the entries from your old config.js file, 1 by 1 into your new config.js file.
Test run after each copy

Can’t I just copy everything over all at once?

You can, but if something fails in the process, you’ll be back to troubleshooting again. It’s
a whole lot safer doing it 1 by 1 and running the mirror after each addition as a test.

Backup your config.js file

Each time you add a module and its config.js entry, run the mirror. If it works, backup your
config.js file. If it doesn’t work, you know it’s the addition you just made. If you make
bulk additions and it fails, you’ll hear yourself say, “I should have listened to Mykle!”

Peace

edit:
with

sudo netstat -lnptu

i saw that electron.js is already using the port. But i have a blank screen and nothing is shown. Also rebooted a couple of times.

Hmm, make sure you only have 1 terminal open when you run npm start from the pi@user/MagicMirror directory. Also, make sure the address: "0.0.0.0", entry in your config is OUTSIDE the whitelist. If you’re running pm2 make sure that is not launching an instance of MM. Otherwise, is there anything else that you changed after the install?

How do you apply after each module you try out? Is there a way or do you have to reboot every time?

You don’t have to reboot the Pi to launch MM after adding a module. Assuming you quit MM before you added the module, you simply launch MM as you normally would

@Mykle1
The MM autostarts when booting up the Pi, what’s the command you use to apply/run the config.js right after you save it?

When the mirror is running, press your Alt key to drop down a menu bar. Choose Minimize from the Window menu. Assuming pm2 is autostarting for you, open a terminal and type pm2 stop mm to quit MM.

You can start MM after saving your config in the terminal by typing pm2 start mm, or if MM is still running, from the drop down menu, View, Reload

The problem was the module watchdog !
Also with fresh install it throws errors with the newest update.

Fixed for me. Thank you @Mykle1 !!!
