Build Blockly problem

Describe the bug

I downloaded the source code from: https://github.com/google/blockly/releases/tag/6.20210701.0 I am going to modify the source code to add some features and before doing so, I tried to build the downloaded and unmodified source code using: npm run build:core

The following is from the log:

To Reproduce

1. Installed Git (2.32.0.2)
2. Install Node.js (14.17.3 )
3. Download the source code from: https://github.com/google/blockly/releases/tag/6.20210701.0. Unzip it.
4. Inside the folder run: npm ci
5. Inside the folder run: npm run build:core

I have followed the document: https://developers.google.com/blockly/guides/modify/web/building. However, it does not mention Git, do I need to install it in order to rebuild the source? Any help is much appreciated. Thanks a lot!
