在尝试使用堆栈安装ThreadScope时出现依赖问题。这个问题似乎是围绕着cairo-0.13.8.1

Question

我正在尝试使用stack install threadscope安装ThreadScope。

Stack向我推荐了要添加到我的全局stack.yaml文件中的包。我听从了它所有的建议。这来自~/.stack/global-project/stack.yaml：

extra-deps:
- gtk2hs-buildtools-0.13.8.0
- cairo-0.13.8.1
- glib-0.13.8.1
- gtk-0.15.5
- pango-0.13.8.1
- gio-0.13.8.1

然后我运行：

stack install threadscope

cairo      > [1 of 2] Compiling Main             ( /tmp/stack-aa04726c2a449768/cairo-0.13.8.1/Setup.hs, /tmp/stack-aa04726c2a449768/cairo-0.13.8.1/.stack-work/dist/x86_64-linux-tinfo6/Cabal-3.0.1.0/setup/Main.o )

好的，开罗似乎是问题所在。

在这个错误中，我最感兴趣的是一行代码：setup: The pkg-config package 'cairo' version ==1.2.0 || >1.2.0 is required。嗯，这是否意味着我应该首先尝试安装较旧版本的Cairo？我试过了，但没有任何运气。

我已经尝试运行以下命令：

stack upgrade --git --source-only
stack build cairo

当我运行stack install cairo时，我得到了相同的错误。

如果我运行which stack，我会返回/home/nick/.local/bin/stack

最后，下面是如果我尝试stack install gtk2hs-buildtools会发生什么

Answer 1

pkg-config正在寻找一个名为cairo的包，这个包可能会让人感到困惑，因为它与Haskell cairo包具有相同的名称。这是构建日志中有用的部分：

cairo> setup: The pkg-config package 'cairo' version ==1.2.0 || >1.2.0 is required
cairo> but it could not be found.

pkg-config正在PKG_CONFIG_PATH中搜索名为cairo.pc的文件。在Debian上，这是由libcairo2-dev包提供的。
