如何在 Ubuntu 上安装“colorls”？

我想安装色彩. 看起来很方便：

我尝试跟随安装说明。然而，它们似乎不是为 Ubuntu 制作的。

首先，因为gem不存在，所以我必须逃跑sudo apt install ruby-rubygems。

现在，当我尝试安装它时遇到此错误：

$ gem install colorls
Fetching colorls-1.4.6.gem
...
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/3.0.0 directory.

所以我尝试使用--user-install标志：

$ gem install --user-install colorls
WARNING:  You don't have /home/flimm/.local/share/gem/ruby/3.0.0/bin in your PATH,
      gem executables will not run.

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

extconf failed, exit code 1

Gem files will remain installed in /home/flimm/.local/share/gem/ruby/3.0.0/gems/clocale-0.0.4 for inspection.

如何在 Ubuntu 上安装（和卸载）colorls？

答案1

  1. 安装带有开发标头的 Ruby Gem：

    sudo apt install ruby-rubygems ruby-dev

  2. 下载并安装 Nerd 字体（需要安装才能正确显示漂亮的图标）。打开下载的存档文件，打开每个字体文件，然后单击“安装”按钮：

  3. 设置你的终端以使用该字体。（此步骤可能不需要）

  4. 安装colorls：

     $ gem install --user-install colorls
 WARNING:  You don't have /home/flimm/.local/share/gem/ruby/3.0.0/bin in your PATH,
       gem executables will not run.
 ...

  5. 如果前面的命令警告您路径中没有正确的位置，请修改~/.bashrc（或在您最喜欢的 shell 中进行等效操作）以添加此行，以修改您的 PATH：

     PATH="$PATH:$HOME/.local/share/gem/ruby/3.0.0/bin"

  6. 要添加制表符补全，请将这一行添加到~/.bashrc（或在您最喜欢的 shell 中添加等效行）：

     source $(dirname $(gem which colorls))/tab_complete.sh

  7. 现在重启你的终端。你现在就可以运行了colorls，新字体也会生效。

要卸载 colorls，请运行gem uninstall colorls并删除 中添加的行~/.bashrc。您可能还想撤消依赖项的安装。
