Snapcraft 失败：[Errno 21] 是一个目录：'/path/to/snap/prime/'。

我正在尝试拍摄这个项目，事实证明这是一个相当大的挑战。我不得不编写不少于 3 个自定义插件，但此时所有部分都已完成暂存。然而，在暂存所有内容后，Snapcraft 失败并出现主题中的错误。

这是我的 snapcraft.yaml：

name: stakeweightedvoting-app
version: "0.1"
summary: A blockchain-based secure voting and polling application
description: Stake Weighted Voting is Follow My Vote's application for stake-weighted voting on a blockchain. The app allows users to create and vote on polls on a blockchain, and securely tallying and displaying the results to ensure that no fraud can occur undetected.
confinement: devmode

apps:
  VotingApp:
    # If this actually works, I'll eat my hat. Can't fix it until I can build a snap, though...
    command: . $SNAP/opt/qt57/bin/qt57-env.sh && VotingApp

我可以为这三个自定义插件提供源代码，但是在构建步骤之后它们都不会覆盖任何内容，所以我暂时省略它们。

我发现这个错误这可能就是我所看到的，但是这种解决方法对我来说不起作用。

答案1

command: . $SNAP/opt/qt57/bin/qt57-env.sh && VotingApp不起作用，因为您需要提供snap目录内的实际文件，并且.这是您收到的错误的结果。

但是您可以编写自己的包装脚本：

#!/bin/sh

source $SNAP/opt/qt57/bin/qt57-env.sh

exec VotingApp $*

并将其作为command条目。

做一些类似的事情tomcat 演示使用wrapper（但你不需要Makefile，只需使用dump插件即可，如蚊子演示）
