在 macOS 和 zsh 上安装 Colorls

Question

我想安装 Colorls。我是 Ruby 的新手。要安装 Colorls，我执行了：

gem install colorls --user-install

经过一段时间（可能是在我安装了 Anaconda 之后）Colorls 不再工作了。 zsh：找不到命令：colorls

这里有一些信息：

Answer 1

您的 ruby 版本可能与 gem 版本不匹配吗？似乎是

中的次要版本

/usr/local/Cellar/ruby/2.6.1/lib/ruby/gems/2.6.0

确保您仍然安装了 gem：

which colorls

#should output something like:  /Users/yourusername/.rvm/gems/ruby-2.6.0/bin/colorls

查看是否确实安装了gem

gem list colorls

然后也许尝试重新安装 https://github.com/athityakumar/colorls#install

您可能想使用版本管理器，我推荐 RVM 参见 https://rvm.io/rvm/install

Answer 2

我在重新格式化 Mac 时总是忘记如何安装 colorls。我有：

macOS Catalina Version 10.15.7（不要错过预装的ruby）

我遵循以下步骤：

步骤-1-

使用自制程序安装ruby

brew install ruby

步骤-2-

进入目录

cd /usr/local/Celler/ruby/<x.x.x>/bin
# Or for ARM Mac I use here 3.1.1 that comes with brew install ruby
cd /opt/homebrew/Cellar/ruby/3.1.1/bin
# Then 
./gem install colorls

我的版本是 (3.0.1)

步骤-3-

现在您可以link将此库设置为您之前安装的默认库（按照 colorls 的 GitHub 回购步骤）

ln -s /usr/local/lib/ruby/gems/x.x.x/bin/colorls /usr/local/bin/colorls

# or for ARM Mac I use here gem 3.1.0
ln -s /opt/homebrew/lib/ruby/gems/3.1.0/bin/colorls /usr/local/bin/colorls

提示：如果您在执行 link 命令之前在目录中发现任何其他颜色，请将其删除。现在检查：
