我正在使用 High Sierra，无法通过 brew install 安装图形工具。下面给出的是 brew 安装后的输出。
> brew install graph-tool
graph-tool: macOS Mojave or newer is required.
Error: An unsatisfied requirement failed this build.
由于我使用的是一台有点锁定的机器，所以我无法更新到 Mojave。我以前能够brew install graph-tool在 High Sierra 上毫无问题。
graph-tool的自制公式链接似乎表明它现在仅适用于 Mojave。公式本身也是如此。
https://github.com/Homebrew/homebrew-core/blob/master/Formula/graph-tool.rb
depends_on :macos => :mojave # for C++17
有没有办法可以在我的机器上安装旧版本的图形工具？
更新
这可能不适用于大多数人。但由于安装 graph_tool 非常费力，我想我会在这里复制我的解决方案。
在尝试 bfontaine 的解决方案时，我不断收到以下错误：

我意识到我不会使用图形工具的（优秀）功能进行可视化，所以我下载了 bfontaine 在下面链接的 graph_tool.rb 文件，从中删除了 matplotlib 依赖项，然后运行brew install --build-from-source ~/Downloads/graph-tool.rb.
然后我将 numpy 降级到 1.16.1，graph_tool 按预期工作！
同样，仅当您不打算使用 graph_tool 的可视化功能时才这样做。
请参阅下面的修改后的 graph_tool.rb 文件。
