通过堆栈安装IHaskell出现问题，进程已退出，代码为: ExitFailure 1

Question

我在为Jupyter notebook安装IHaskell时遇到了一个问题，我对MacOS这个过程的说明是

https://github.com/gibiansky/IHaskell

特别是

brew install python3 zeromq libmagic cairo pkg-config haskell-stack pango
git clone https://github.com/gibiansky/IHaskell
cd IHaskell
pip3 install -r requirements.txt 
stack install --fast
ihaskell install --stack

一切都很顺利，直到我遇到退出失败的堆栈安装

stack install --fast

Answer 1

问题是在zeromq找不到PKG_CONFIG_PATH，在not之前

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:`brew --prefix`/lib/pkgconfig

一切正常
