1.1 Download and install
(1) Tsinghua mirror image download : download link .
- Choose the latest dated x64 version.

- Manually add environment variables: Open the computer search (shortcut key: win key + q), search for environment variables, then click in turn according to the picture, add the four paths as shown in the picture (the installation path of your own computer)
