Aus*_*n T 5 permissions curl haskell ghcup
我尝试在 Ubuntu 上安装 ghcup:
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
使用默认选项(添加到 .bashrc 之前,不安装 HLS,不安装 Stack)。
问题是,permission denied当脚本尝试将ghcup-0.0.6.yaml.tmp文件写入~/.ghcup/cache目录时,我收到错误,但我不确定原因。
该目录的权限为 1775 (drwxrwxr-x)。将它们升级到 1777 (drwxrwxrwt) 并重新运行curl 命令会产生相同的错误。目录所有者是我(不是 root),并且我正在运行 curl 命令,而没有sudo按照 ghcup 安装说明的指示。
完整命令输出:

希望能解释一下发生了什么以及如何解决它,以便我可以开始学习 Haskell!提前致谢。
解决了:
事实证明,snapcurl 的版本是半损坏的。ghcup运行后我安装成功:
sudo snap remove curl
sudo apt install curl
