Hi, how do I run emulator on Ubuntu 21.10?

OMGlinuxIS · February 13, 2022, 11:13pm

how? I asked how to install and run the inventor app step by step ', several people wrote, but none of them has NO CONCEPT of how it is done, they just thoughtlessly copied the code to be pasted in the terminal. why do such people write to me? I don't know something, I don't say anything.

This is the third time you have been informed about using capitals. Did you read Tim's previous post?

OMGlinuxIS · February 13, 2022, 11:21pm

can you tell step by step where to put this file? I really asked one question:
Can anyone explain step by step how to install and run it? I write in capital letters to emphasize important information, but as I see everyone does not care. I asked for a step by step explanation of what to do, is there anyone who knows app inventor on Linux?

If you get cross with the world, it is likely that the world will just stop trying to help you

Stay calm, work through the steps, and all should become clear, and hopefully the installation process will work.

I am one of a several people on the community who uses linux, I have been using linux with AppInventor since 2013.

As I indicated in a previous post, the commands indicated worked for me (and subsequently other users) to get the AI2 emulator up and running on Linux

It is (although you could also try Stack Overflow, but they will likely point you back here...)
And you are in the MIT AppInventor community

Open a terminal (as described above)
Type cd and press Enter
You should now be in your home directory
Type sudo rm -rf /usr/google/appinventor and press Enter (you may be asked for your password)
Type sudo rm -rf ~/.appinventor and press Enter
Type sudo apt-get update and press Enter
Type sudo apt-get upgrade and press Enter
Type sudo apt-get install lib32z1 and press Enter
Type sudo apt-get install lib32stdc++6 and press Enter

Now locate the directory that contains the deb file: appinventor2-setup_2.3_all.deb
You will need to cd to that directory or copy the file to your home directory

Type sudo dpkg -i appinventor2-setup_2.3_all.deb and press Enter
Type cd and press Enter
Type /usr/google/appinventor/commands-for-Appinventor/aiStarter & and press Enter to start the AI2 Emulator Starter

Once this is running you can go to http://ai2.appinventor.mit.edu/ in your browser, open a project, then click on Connect then Emulator to commence connection

If you get any errors after running any of the commands, report these back here.

how? I can't paste anything into "home" directory, there is no option "paste" in this directory. It is impossible.

"wklej" in menu is "paste". I cant do it.

TIMAI2 · February 13, 2022, 11:47pm

Is pan your username ?

If so double click on that to open that folder (which is your home directory)

then you should be able to paste?

OMGlinuxIS · February 13, 2022, 11:49pm

so paste in computer/home directory or in my computer/home/username directory?
can you be precise and explain where should i paste this file exactly?

TIMAI2 · February 13, 2022, 11:49pm

in your computer/home/username directory

and, not working.

TIMAI2 · February 13, 2022, 11:58pm

Did you run CTRL-C ?

OMGlinuxIS · February 14, 2022, 12:00am

no, i only wrote command:

/usr/google/appinventor/commands-for-Appinventor/aiStarter &

thats is last thing i've made.

TIMAI2 · February 14, 2022, 12:05am

OK, it looks like there is a leftover process running on that port. Try closing the terminal, then open the terminal again, and try running the last command /usr/google/appinventor/commands-for-Appinventor/aiStarter & again.

not working.

TIMAI2 · February 14, 2022, 12:16am

Hmmm, the program appears to be starting up OK, but not sure why it is then shutting itself down?

Might require input from the AI2 devs, unlikely to get a response tonight, with the SuperBowl on right now

Will assign, you will just have to be patient.

You could try restarting your computer, and running the command again....

OMGlinuxIS · February 14, 2022, 12:19am

thanks for help, but I think nobody will help with it. Rather, I'm going to waste more time and nerves on this before I trigger it. And I thought that I would program myself from blocks. But without the emulator, there is no point in compiling the program every now and then and installing it on the phone to check how it works.

and in web when i try to connect with emulator:

The aiStarter helper does not appear to be running
Need Help?

TIMAI2 · February 14, 2022, 12:43am

OK, well done, getting closer

The installation appears to now be working OK, and starting up, but now not connecting....
(Did you have a project open ?)

The Need Help link doesn't really help because it just takes you to the AI2 home page.

This page:
http://appinventor.mit.edu/explore/ai2/connect-help-emulator
though Windows-centric may offer some things you can try...

OMGlinuxIS · February 14, 2022, 1:13am

Yes, project was open when i tried to connect. I'll tried with closed project too- nothing.
