无法创建.gitignore文件，提示必须输入文件名称

If you're using Windows it will not let you create a file without a filename in Windows Explorer. It will give you the error "You must type a file name" if you try to rename a text file as .gitignore



To get around this I used the following steps

Create the text file gitignore.txt

Open it in a text editor and add your rules, then save and close

Hold SHIFT, right click the folder you're in, then select Open command window here

Then rename the file in the command line, with

ren gitignore.txt .gitignore
