Sorry, when I said Git for Windows, I meant a terminal emulator: https://gitforwindows.org/

Do you mean GIT Bash? Because I already have it.

That's annoying! I'm not sure, but you could try an unofficial port of NVM, a version manager of Node and NPM, for Windows, here: https://github.com/coreybutler/nvm-windows – and use that to install Node.js.

Do you know how to use it? I installed it but then I couldn't figure out what to do with it.

If I try to link scratch-blocks, it fails.
In the building step for scratch-blocks, it requires a Python library that I think is broken on Windows. On MacOS and Linux, it compiles properly. Is it possible for you to use a Bash terminal, such as the one that comes with GitHub, or using Windows Subsystem for Linux? Either way *should* work, but I'm now using Mac, so I can't confirm. Otherwise, using the online compiler, which is used when Java isn't available, definitely works on Windows. To do that, you can remove Java from your path while you compile Scratch Blocks.
I used Git Bash. I also tried the normal CMD, but it didn't work either.
Is it possible for you to temporarily remove Java from your path to compile? That's not the ideal solution but I know it works

I don't know how to remove Java and I still need it for other things outside of Scratch.

You can follow these instructions to temporarily remove Java from your path. Once the compiler has started running online, you could then re-add java to the path. This doesn't install or uninstall Java at all, but when you remove an item from your path, you lose access to it in a command line. So, by removing Java from your path, Scratch Blocks will compile with the online compiler. Then you can put it back in so that other applications can use it. It's difficult for me to try to find other solutions for this issue, because I'm now using MacOS. However, if I find anything, I'll be sure to tell you and update the post.

Or, if you're using Windows 10 Pro, you can Use Windows Subsystem for Linux to get a proper bash terminal (it's a feature in only the pro versions of Windows 10).

Ok, I'm trying to mod Scratch 3 again, using this sticky, but this time I downloaded Node as a zip file. But when I put “npm install”, this happens in the Command Prompt:
C:\Users\...\Scratch_Mod\scratch-gui> npm install
'npm' is not recognized as an internal or external command, operable program or batch file.
And Node is in that folder. I even set the location of my environment variables to the Node folder that is in the scratch-gui folder.

Just to be clear, you have the path to the node-vversion-win-x64 or 32 in your Path environment variable? And the Node and NPM commands still don't work?

I installed Node as a zip file(and then unzipped it) because in the real installation program, the progress bar doesn't go up at all. When I unzipped the Node(zip) file, I set the environment variables to the folder where all of the files of Node are, which is:

C:\Users\...\Scratch_Mod\scratch-gui\Node

Then, in the command prompt, I used:

cd scratch-gui
node -v
npm install

And then it said that Node and NPM did not exist.

Is there a `node.exe` file in your Node folder? If not, could you run `tree` when inside the folder and show us the output?

As the error from C:\Users\…\Scratch_Mod\scratch-gui\Node -v (check node version)
I think your installation of node was not successfully. OR your Path point to wrong directory(Edit the system environment variables)
I suggest these steps:
1) uninstall all node program from your Windows
1.1) use windows Add remove Programs
1.2) manual delete node unzipped files
2) reinstall node-v10.15.0-x64.msi from https://nodejs.org/en/download
3) try node -v

If you do clean installation from nodejs website
1) node.exe is located in C:\Program files\nodejs\node.exe
2) npm.cmd is located in both C:\Program files\nodejs\npm.cmd
3) and in C:\Users\%your-login-name%\AppData\Roaming\npm.cmd

AmazingMech2418

Could you possibly mod from Scratch 3.0 Desktop?

Never mind about my problem, I had a ZIP file that did have the node.exe file in it, so then I unzipped it. Now, the “node -v” command works. In the command prompt, now this happens:

C:\Users\...\Scratch_Mod\scratch-gui> node -v
v10.15.0

Now I have a new problem…

Nice work!

`npm start` won't work until `npm install` finishes correctly. In your case, `git` isn't running. Use “Git Bash” to run those commands so that `git` will work correctly.

You should be able to ignore all of the warnings. Were there any actual errors?

Perhaps you haven't installed webpack properly. Try running `npm install` again on Git Bash, then try `npm start` again

When I install NPM, all GIT Bash does is give 4 warnings and then it does nothing else(it doesn't end the command and does do nothing).

Scratch GUI has a lot of dependencies, so installing it takes quite some time. NPM outputs warnings as it goes (but doesn't output anything if there's nothing wrong), then it becomes silent as it loads a big dependency.

Try again and wait a bit longer maybe
