I followed instructions of how to install Node and npm with No Administrator's permission and now this happens:
C:\Users\*censored due to name reveal*\scratch-gui> npm install
'npm' is not recognized as an internal command or external command, operable program or batch file.
Please Answer

npm is a nodejs package installer. It needs to be downloaded.

Holy cow, the cloning is taking a while!

Well I mean, it could be worse.
It could be a Raspbian update!

MrMeowington

If you're using Linux, you might want to run the install command with root privileges…

sudo npm install

Sudo doesn't work in Batch. Bash can use sudo, though.

Yeah, I just realized that I wasn't very clear on that and was just coming back to fix it.
Only Linux users can enter ‘sudo’ at the terminal.

Actually, Mac users (and I think Unix too) can also use sudo at their terminals

Yes, but not Windows.

please use su instead.

Hi JGames101 and everyone, I tried

git clone git@github.com:LLK/scratch-gui.git

but I get the following error message:

git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

Am I doing something wrong?

Trying the GUI version of Git I get a similar error message:

Warning: Permanently added the RSA host key for IP address ‘192.30.253.113’ to the list of known hosts.
git clone git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

I solved the clone problem by using the “Clone existing repository” in the GUI version of github and using

https://github.com/LLK/scratch-gui.git

as Source Location, as suggested at https://github.com/LLK/scratch-gui. Then, after installing and starting it, I got Scratch 3 correctly working at localhost:8601. Thanks JGames101!

I've modified Scratch blocks and made the blocks less fat. I also added back the square string inputs and flipped the colours of the events and control blocks.

I like a lot the thinner blocks! How did you get that? I just downloaded the source code and made it run in node.js, so I really don't know where to start

I don't recall exactly what I did, but you can see my changes here. Most of my changes were made in core/block_render_svg_vertical.js

I believe I had some trouble building it to gh-pages because I didn't have Python, so I just manually moved my files over to the other branch and that worked.

When I run

npm link

I get an error complaining that I have no Python installed. Why do I need Python in order to change Scratch 3 source code? Isn't it just Javascript?

After having installed python (version 2.x; version 3.x apparently DOESN'T work with the Scratch 3 source code) I get the following error when I run “npm link”:

Is there anyone following this thread that knows how to work on Scratch 3 source code? It seems that JGames101 is not monitoring it

I used Glitch, but Scratch 3 kept having updates so the code got messed up for me. The only solution now is to wait until Scratch 3 actually releases and then use Glitch to edit the Scratch 3 source code.

I'm in the process of rewriting the post now. I've been away from Scratch for a while but I am now much more familiar with npm than I was at the time I originally wrote it.

The new instructions addresses this issue with a workaround. I'm looking into a proper fix. Is it possible for you to run the code in an environment without Java installed? If so, try running the command without java, in which case it uses the web version to compile, which should work successfully. I'm looking into how to make it work without this workaround.
