Failed to run demo.sh due to a compilation error in the miniscript package.

What went wrong

Running bash demo.sh results in an error, failing to compile bdk-cli.
The root cause is the miniscript package, on which bdk-cli indirectly depends.

rgb-sandbox version: v0.10 or the commit d2707b9.

To work around this issue, set BDK_CLI_VER="0.26.0" in demo.sh. This will complete the script, but it is uncertain whether the demo will work correctly.

Details

The exact error is as follows:

ERROR: error installing bdk-cli

This is a known issue already reported in the miniscript repo.
rust-bitcoin/rust-miniscript#549

Miniscript v9.0.2 fixes this issue.
However, bdk-cli v0.27.1, which is used by rgb-sandbox, depends on bdk v0.27.1, which in turn relies on miniscript v9.0.

RGB-Tools/rgb-lib#27 is related issue.

Unfortunately bdk-cli's latest version is still 0.27.1, so I worked around this by installing bdk-cli in debug mode.

This is available in the updated master branch (commit 2f4e2ba) so closing this, feel free to re-open if needed.
