installation error

[toshima1051]

I am getting an installation error.
Any guidance on how to resolve this issue would be appreciated.
Details of the error are in the attached text file.

I am not familiar with github, so sorry if I am asking the wrong thing.
Also I am Japanese so I am using machine translation
Best regards.

Hey. Looks like download of assets is failing for some reason. I would suggest you try executing the same install command again few times, as this usually solves random failures. If that does not work, the download servers might be blocked where you try to download things, and for that I have no solution unfortunately :(
