cabal install的默认行为是将可执行文件安装到cabal的软件包存储中，并在目标目录中创建符号链接（在Linux上默认为~/.cabal/bin）。如果您只想从路径中删除可执行文件，删除符号链接就足够了。
目前，cabal没有卸载命令。如果需要回收磁盘空间，最直接的方法是删除存储区。关于此事，用户指南中有以下内容：
全局软件包存储是
~/.cabal/store（可以通过全局的store-dir选项进行配置）；如果您需要出于任何原因清除存储区（例如为了回收磁盘空间或因为全局存储区损坏），删除此目录是安全的（v2-build将在下一次调用时重新构建它所需的一切）。
英文:
The default behaviour of cabal install is to install the executable to cabal's package store and create a symlink to it in the destination directory (which, in Linux, defaults to ~/.cabal/bin). If you just want to remove the executable from your path, deleting the symlink is enough.
cabal currently doesn't have a uninstall command. If there's a need to reclaim disk space, the most straightforward way to do so is deleting the store. Here is what the User's Guide has to say on the matter:
> The global package store is ~/.cabal/store (configurable via global store-dir option); if you need to clear your store for whatever reason (e.g., to reclaim disk space or because the global store is corrupted), deleting this directory is safe (v2-build will just rebuild everything it needs on its next invocation).
