我正在尝试在我的服务器上安装一个运行在Cabal中的Haskell服务器。当我正常配置服务器来运行它时，我遵循这些我们已经改进的说明 - 它们每次都在空白的机架空间云服务器上100％工作。
yum update
yum install git
yum install vim
yum install ghc-zlib-devel.x86_64
wget http://www.haskell.org/ghc/dist/7.8.2/ghc-7.8.2-x86_64-unknown-linux-centos65.tar.xz
wget http://www.haskell.org/cabal/release/cabal-install-1.20.0.1/cabal-x86_64-unknown-linux.tar.gz
tar xvfJ ghc-7.8.2-x86_64-unknown-linux-centos65.tar.xz
tar -zxvf cabal-x86_64-unknown-linux.tar.gz
cd ghc-7.8.2
./configure
yum install gcc
./configure
make install
cd ../
git clone https://github.com/samheather/DSA-WAW.git
cd DSA-WAW/server
cp -r ../../cabal cabal
./cabal update
./cabal install cabal-install
./cabal sandbox init
cabal install
然后我可以直接导航到输出文件夹并运行服务器。
但是，在我的iWeb专用服务器上，这不起作用。大多数步骤都很好，直到它达到'./cabal install cabal-install'，它会引发以下错误：
./cabal install cabal-install

有没有人知道这有什么问题？
谢谢，

更新：我应该提一下，因为服务器已经有gcc我们跳过这两步：“yum install gcc; ./configure”
答案 0 :(得分：5)
之前安装zlib1g-dev软件包。
答案 1 :(得分：3)
/tmp删除粘性位）。相反，我从Github下载了cabal v1.20.2并执行了bootstrap.sh脚本，请参阅README。
答案 2 :(得分：2)
我刚想出来了 - 我的/ tmp没有exec权限。由于服务器运行WHM / cPanel，我刚刚运行/scripts/securetmp，同时回答n。
答案 3 :(得分：1)
我修复了与ghc-pkg recache类似的错误，这些错误实际上是在失败的构建过程中提到的，也许我重新安装了具有相同版本的Haskell平台。
