Swift Package 使用过程遇到的问题

1.error: manifest parse error(s): Invalid version string: 2.0

• 问题：tag标签版本号不规范，不足三位数
• 解决：
  • 设置三位数的版本号，如：1.9.0
  • 具体设置依赖关系如下：.package(url: "https://github.com/kawoou/FlexibleImage", .upToNextMajor(from: "1.8.0"))

2.error: dependency graph is unresolvable; found these conflicting requirements

• Dependencies: https://github.com/kawoou/FlexibleImage @ 1.8.0..<2.0.0

• 问题：git参数的tag不存在三位数的标签
• 解决：
  • 在git中新建tag v1.8.0 并推到远程到仓库中,不是自己的仓库需要fork至自己个人仓库在推送。
  • 具体设置依赖关系如下： .package(url: "https://github.com/tomlee130/FlexibleImage", .upToNextMajor(from: "1.8.0"))
  • 然后重试swfit package udpate

3.warning: target 'FlexibleImage' in package 'FlexibleImage' contains no valid source files

• error: target 'FlexibleImage' referenced in product 'FlexibleImage' could not be found

• error: product dependency 'FlexibleImage' not found

• 问题：依赖库工程FlexibleImage不是一个规范的swift library结构，少了一级FlexibleImage目录
  • |____Sources
    | |____Abstract
    | | |____ImageDevice.swift
    | | |____ImageFilter.swift
    | |____Device
    | | |____ImageMetalDevice.swift
    | | |____ImageNoneDevice.swift
    | |____Filter
    | | |____AddFilter.metal
    | | |____AddFilter.swift
    | |____FlexibleImage.swift
    
• 解决：调整工程目录
  
  • $> mkdir -p FlexibleImage && cd FlexibleImage
    
  • $> swift package init --type library # 初始化为一个库
    
  • $> cp Package.swift tomlee130/FlexibleImage
    
  • $> mkdir -p Sources/FlexibleImage
    
  • $> cp tomlee130/FlexibleImage/Sources/* tomlee130/FlexibleImage/Sources/FlexibleImage/
    
  • so，目录结构如下，
    
  • |____Sources
    | |____FlexibleImage
    | | |____Abstract
    | | | |____ImageDevice.swift
    | | | |____ImageFilter.swift
    | | |____Device
    | | | |____ImageMetalDevice.swift
    | | | |____ImageNoneDevice.swift
    | | |____Filter
    | | | |____AddFilter.metal
    | | | |____AddFilter.swift
    | | |____FlexibleImage.swift
    | | |____Type
