在Mac上

你可以创建一个新的文本文件。

使用https://www.gitignore.io/添加内容

保存文件，文件格式为-富文本文档与附件。

将文件名更改为.gitingore 并选择使用“。”当弹出弹出如图所示的图像。

注意:由于它是一个隐藏文件，您将无法在目录中看到它。但它会被创造出来。

您可以直接创建一个空的.gitignore文件。在你需要添加该文件的位置打开cmd，并键入以下命令:

copy con .gitignore

按回车。我们现在处于新创建文件的编辑模式，但现在不需要添加任何东西。只需按F6，然后按Enter。

现在您有了一个空的.gitignore文件。在您拥有的任何编辑器中编辑您的文件。

在工作中，我们使用的是Windows XP系统，在文件名后面输入句号是行不通的。创建.gitignore文件而不会出现“你必须输入文件名”错误的快速简单的方法是:

打开CMD窗口，输入“edit .gitignore”。 键入“Alt(选择文件菜单)，F, s，你现在有一个空的.gitignore文件，无论你的cmd提示符指向哪里。

现在可以用您喜欢的文本编辑器填充它。
