无法运行我的 Snap 包（由 Rust 应用程序构建）

Question

This is how my snapcraft.yaml looks like (at the root of my Rust project):

name: keval-snap 
base: core20 
version: '0.1'
summary: Single-line elevator pitch for your amazing snap # 79 char long summary
description: |
  This is my-snap's description. You have a paragraph or two to tell the
  most important story about your snap. Keep it under 100 words though,
  we live in tweetspace and your description wants to look good in the snap
  store.

grade: stable
confinement: strict

apps:
  keval-snap:
    command: bin/keval-snap
    daemon: simple

parts:
  my-part:
    plugin: rust
    source: .
    build-packages:
      - pkg-config
      - libssl-dev

And my Cargo.toml :

[package]
name = "my-package"
version = "0.1.0"
edition = "2021"
default-run = "keval-snap"

[[bin]] # Bin to run the http client
name = "keval-snap"
path = "src/main.rs"
doc = false
.............

After creating the YAML I did

snapcraft

snapcraft upload --release=stable keval-snap_0.1_amd64.snap

I can see my package on my Snapcraft account

Then, I Installed with snap install keval-snap

The only thing is when I run keval-snap --help it says command not found !

I expect to see the possible commands and options here.

Is there anything wrong with snapcraft.yaml OR cargo.toml ?

Answer 1

The issue was mismatching names. I used snapcraft --debug and saw all the files inside VM.

Turns out, application command name should match with part name. I had my code built inside bin/my-part , and I was calling the command bin/keval-snap

Changed my part name to keval-snap & Issue was resolved !
