我正在尝试直接按照此处的说明在jupyter 中安装 IHaskell 。
我跑了以下。
sudo apt-get install -y python3-pip git libtinfo-dev libzmq3-dev libcairo2-dev libpango1.0-dev libmagic-dev libblas-dev liblapack-dev
git clone https://github.com/gibiansky/IHaskell
cd IHaskell
pip3 install -r requirements.txt
stack install gtk2hs-buildtools
# stack install --fast
# ihaskell install --stack
# jupyter labextension install ihaskell_jupyterlab
我在上面的第 5 个命令中遇到了这个错误，即gtk2hs-buildtools：
(envname) me@machine:~/plc/IHaskell$ stack install gtk2hs-buildtools

Process exited with code: ExitFailure 1
一些搜索告诉我cannot find -lgmp是通过以下方式解决的：
$ sudo apt-get install libgmp3-dev
我这样做了。这安装成功，但是
(envname) me@machine:~/plc/IHaskell$ stack install gtk2hs-buildtools
仍然产生相同的错误。出了什么问题，我该如何解决？
从 scinart 的建议更新
$ conda install gmp

该死，和以前一样的错误。
所以，从这里，你可以看到我已经安装了 gmp 包，实际上已经有一个更高的版本。问题似乎是链接器由于某种原因无法找到 gmp（即使它存在），因此重新安装 gmp 将无济于事。
更新 2
我尝试的另一件事是：
$ conda install gxx_linux-64
推荐这里，也没有用。
更新 3
这看起来也像同样的问题，以这种方式解决，但对我不起作用。
