Homebrew 无法下载安装文件的解决方法_error: failed to download resource "docker.rb

Homebrew 无法下载安装文件的解决方法

借鉴自How to install a local file in Homebrew,十分优秀的文章.

---

相信很多小伙伴都或遇到用Homebrew下载、更新一些软件的时候会发生一些让人感慨中国安全的时候。希望这个贴能帮助到你。

打个比方我要更新Dart：

brew upgrade dart  
1

终端会显示：

DownloadError: Failed to download resource "dart"
1

但同时终端回显示下载失败文件的下载网址：

Download failed: https://storage.googleapis.com/dart-archive/channels/stable/release/2.7.2/sdk/dartsdk-macos-x64-release.zip  
1

之后我们就可以用自己浏览器或者下载器下载需要的文件。

之后使用终端查看Homebrew的缓存地址：

brew --cache  
1

打印出以下地址：

/Users/<UserName>/Library/Caches/Homebrew  
1

最后将下载下来的文件拷贝到缓存地址：

cp ~/Downloads/dartsdk-macos-x64-release.zip /Users/<UserName>/Library/Caches/Homebrew    
1

最后使用Homebrew安装，这个时候就可以成功了。

Hint：其实只要科学上网这些都不是事。

更新一波。
上网的时候看到了有大佬的博客已经“完整系统”地解决了这个问题。

如果上面的操作不能解决这个问题（再次upgrade的时候又报错了）。那么可以使用下面的办法：
先给命令加个 -v 打印命令的详细日志看看:

brew upgrade dart  -v

注意到这条信息:

/usr/bin/curl -q --show-error --user-agent Homebrew/2.1.9-21-g625a780\ \(Macintosh\;\ Intel\ Mac\ OS\ X\ 10.14.2\)\ curl/7.54.0 --fail --location --remote-time --continue-at 0 --output /Users/shockerli/Library/Caches/Homebrew/downloads/4d2412a5d84521393e0e1ecdce0662569e13c2c47762093a760939fa9dd4a917--dartsdk-macos-x64-release.zip.incomplete https://storage.googleapis.com/dart-archive/channels/stable/release/2.4.1/sdk/dartsdk-macos-x64-release.zip

我们看到 Homebrew 下载 dart 的缓存地址为:

/Users/shockerli/Library/Caches/Homebrew/downloads/4d2412a5d84521393e0e1ecdce0662569e13c2c47762093a760939fa9dd4a917--dartsdk-macos-x64-release.zip.incomplete
1

XXX.incomplete 表示下载未完成，但这是 Homebrew 期望的下载文件路径。

那我们就将下载的软件包拷贝到这个路径，并去除 .incomplete:

mv ~/Downloads/dartsdk-macos-x64-release.zip /Users/shockerli/Library/Caches/Homebrew/downloads/4d2412a5d84521393e0e1ecdce0662569e13c2c47762093a760939fa9dd4a917--dartsdk-macos-x64-release.zip

再次执行更新操作，成功收官。

另一个方法：修改软件包的下载地址

具体可见brew edit命令

比如修改 dart 包，brew edit dart：
class Dart < Formula
desc “The Dart SDK”
homepage “https://www.dartlang.org/”

  version "2.4.1"
  if Hardware::CPU.is_64_bit?
    url "https://storage.googleapis.com/dart-archive/channels/stable/release/2.4.1/sdk/dartsdk-macos-x64-release.zip"

    end
  end

  def install
    libexec.install Dir["*"]
    bin.install_symlink "#{libexec}/bin/dart"
    bin.write_exec_script Dir["#{libexec}/bin/{pub,dart?*}"]
  end

我们把 tap 里包对应的 url 给改成可用的地址即可。国内镜像的话，上网找找的话，还是比较简单的，一些大学的镜像做的都比较好。

感谢两位大佬的博客：方法一、方法二。
