youxiaojie,
That error can be triggered by a missing dynamic linker or one of the libraries that bask needs. From an arm64 system.
| Code: | ~ # lddtree /bin/bash
/bin/bash (interpreter => /lib/ld-linux-aarch64.so.1)
libreadline.so.8 => /usr/lib64/libreadline.so.8
libtinfow.so.6 => /lib64/libtinfow.so.6
libtinfo.so.6 => /lib64/libtinfo.so.6
libc.so.6 => /lib64/libc.so.6
ld-linux-aarch64.so.1 => /lib/ld-linux-aarch64.so.1

| Ensure that the mounted device does not have the options noexec, user, or users attached to it. (Check with mount command) |

youxiaojie,
OCR errors fixed
| Code: | /dev/sdb2 on /mnt type ext4 (rw, relatime)
/dev/sdb1 on /mnt/boot type ext4 (rw,relatime) |
If that is you gentoo, that can be made to work.
The handbook uses /mnt/gentoo, not /mnt, so you will need to adjust the other instructions to suit..
You are also missing /prog, /sys and /dev mounted again inside your Gentoo.
The chroot requires those. That's in the handbook too.
