!!! The PACKAGE 'pangoro-runtime' does not match the crate name at 'runtime/pangoro'. Did you mean ''?

Looks like the reason is our crate name does not match "xxx-runtime"? How can I fix this case?

Hello @AsceticBear,

srtoolactually hints what the issue is:

!!! The PACKAGE 'pangoro-runtime' does not match the crate name at 'runtime/pangoro'

As you see, srtool makes the assumption that your runtime lives in runtime/pangoro but that's not the case.

You need to:

• remove the --profile release, it does not hurt but this is deprecated
• provide --runtime-dir set to the proper location of your runtime

You may also check srtool build --help for more details:

srtool-build 0.7.1

Start a new srtool container to build your runtime

USAGE:
    srtool build [FLAGS] [OPTIONS] --package <package> [path]

ARGS:
    <path>    By default, srtool will work in the current folder. If your project is located in
              another location, you can pass it here [default: .]

...
    -r, --runtime-dir <runtime-dir>
            If your runtime is not in the standard location runtime/<chain_name> you can pass this
            args to help srtool find it [env: RUNTIME_DIR=]   

The following will work for you:

srtool build --package pangoro-runtime --runtime-dir node/runtime/pangoro

I am closing this issue since I tested the solution, feel free to re-open if you still run into troubles.
