Eslint expected indentation of 1 tab but found 4 spaces error
提问by JohnSnow
I am using VScode with latest version of Eslint. It is my first time using a linter.
我正在使用 VScode 和最新版本的 Eslint。这是我第一次使用 linter。
I keep getting this linting error when using a tab as indentation:
使用制表符作为缩进时，我不断收到此 linting 错误：
severity: 'Error' message: 'Expected indentation of 1 tab but found 4 spaces. (indent)' at: '4,5' source: 'eslint'
严重性：“错误”消息：“需要缩进 1 个制表符，但发现 4 个空格。(indent)' at: '4,5' 来源：'eslint'
Here is my config file
这是我的配置文件
{
"env": {
"browser": true,
"commonjs": true,
"es6": true,
"node": true
},
"extends": "eslint:recommended",
"rules": {
"indent": [
"error",
"tab"
],
"linebreak-style": [
"error",
"unix"
],
"quotes": [
"error",
"single"
],
"semi": [
"error",
"always"
]
}
}
I don't understand why this error is being thrown as I indicated tabs for indentation. It is obviously calculating my 1 tab as 4 spaced but I don't understand why it is doing that when I am pressing tab for indentation.
我不明白为什么在我指示缩进的制表符时会抛出此错误。它显然是将我的 1 个制表符计算为 4 个间隔，但我不明白为什么当我按下制表符进行缩进时会这样做。
update:The reason is because in VScode using ctrl + shift + ito beautify code will actually use spaces and not tabs. That is the reason.
更新：原因是因为在 VScode 中使用ctrl + shift + i美化代码实际上会使用空格而不是制表符。这就是原因。

In VSCODE, go to menu:
在 VSCODE 中，转到菜单：
File / Preferences / Settingsthen Text Editor(or just search for 'tab' in the search settings box)
File / Preferences / Settings然后Text Editor（或只是在搜索设置框中搜索“标签”）
Then remove the tick from the following settings:
然后从以下设置中删除勾号：
Insert SpacesDetect Indentation
Insert SpacesDetect Indentation
Also to auto format the document with the default VSCode keyboard shortcut use:
还要使用默认的 VSCode 键盘快捷键自动格式化文档，请使用：
Shift+Alt+f
Shift+ Alt+f

Wee, that exactly what it says. You have in your config "indent": [ "error", "tab" ], So it expects tab as indent. But found in your file 4 spaces. Remove spaces and put tab in you file
Wee，这正是它所说的。您的配置中有“缩进”：[“错误”，“制表符”]，因此它期望制表符为缩进。但是在你的文件中发现了4个空格。删除空格并将制表符放入您的文件中

I used VScode to solve this problem. All you have to do is hold the mouse over the part where there is an error.
我用VScode来解决这个问题。您所要做的就是将鼠标悬停在出现错误的部分上。
and...
