运行snapcraft register hello-pward123

返回以下 python 错误堆栈：

我的 snapfile.yaml 看起来像：

name: hello-pward123
version: '2.10'
summary: GNU Hello, the hello world snap
description: |
  GNU hello prints a friendly greeting.
grade: devel
confinement: strict

apps:
  hello:
    command: bin/hello

  bash:
    command: bash

parts:
  gnu-hello:

    plugin: autotools

  gnu-bash:
    source: http://ftp.gnu.org/gnu/bash/bash-4.3.tar.gz
    plugin: autotools
    configflags: ["--infodir=/var/bash/info"]

我在 Ubuntu 16.04.3 上运行 snapcraft 2.33

我们使用click 来解析cli，它需要UTF-8 作为documented here

也就是说，这个错误很不幸，应该修复。
