first problem: if you're running in wsl then install python2 as python if windows then install python 2
second problem: you can press CTRL+Z or CTRL+C to continue doing commands

I tried installing scratch-blocks with WSL and it still didn't work.

SUCCESS: blockly_uncompressed_horizontal.js
SUCCESS: blockly_uncompressed_vertical.js
FATAL ERROR
Required namespace "goog.events.EventWrapper" never defined.
??? at line 57:
goog.requireType('goog.events.EventWrapper');
^

I successfully built scratch-blocks with WSL after adding

goog.require('goog.debug.ErrorHandler');
goog.require('goog.events.EventLike');
goog.require('goog.events.EventWrapper');

to /core/blockly.js.

I had the EXACT SAME ERROR. Delete scratch-blocks and reclone from https://github.com/LLK/scratch-blocks.git (Keep the .git at the end)

What I meant was that npm install was successful after I modified blockly.js, but the editor was crashing, so I cloned scratch-blocks again with .git at the end (I'm cloning TurboWarp's repos, not LLK's) and got the same error I posted above. After re-adding the blockly.js changes and running npm start, the code editor crashes with the same error I got yesterday, which is

lazy scratch-blocks: TypeError: goog.isString is not a function

Edit: I fixed that one, but now I'm getting another similar error:

lazy scratch-blocks: TypeError: goog.isFunction is not a function

The errors never end!

Oops! Something went wrong.

We are so sorry, but it looks like TurboWarp has crashed. Please refresh your page to try again.

lazy scratch-blocks: Error: Field "function(a,b){this.size_=new goog.math.Size(0,0);this.class_=b;this.setValue(a)}" must have a fromJson function

Uhh…. Delete the whole thing, try again, using these links for git cloning:

git clone --depth=1 https://github.com/TurboWarp/scratch-gui.git

git clone https://github.com/TurboWarp/scratch-blocks.git

git clone https://github.com/TurboWarp/scratch-vm.git

Guess what guys! I got a version of scratch running with this tutorial: https://medium.com/@hiroyuki.osaki/how-to-develop-your-own-block-for-scratch-3-0-1b5892026421
Windows Linux subsystem is amazing (though you will have to install yarn for windows linux subsystem: see here: https://yarnpkg.com/getting-started/install)

My name says it all. I'm just a mirror, that's it lol.

I have a question: modding scratch-blocks and scratch-vm is enough to get a fully functional mod of Scratch that will save and load the new blocks?

yes, but you will also need to clone the scratch-gui itself:

git clone --depth=1 https://github.com/LLK/scratch-gui.git

Excellent, thanks. I really hoped that.

Can I edit the source code like a wiki?

If your new blog appears red and without text in the GUI, and you have added it in the scratch-blocks folder and built scratch-blocks, try following the Build steps below. That has always fixed this issue for me, although the cause is unknown. When I find the actual cause and the solution, this post will be updated.

I did everything until the final build step (I'm using macOS BigSur). The new block is now red for me, with no name. It works (when I click it, the cat does 100 steps) but it is red, with no name on it. The build step didn't solve the problem.

So I redid everything from scratch, by checking the block look at every step. The new block stays blue -and its text is “move 100 steps”- until I run

npm link scratch-vm

After running this line, the blocks suddenly gets red.

Is there someone that can take advantage of this precise debug and understand where the problem is?
