quote_type = single

将此添加到.editorconfig中

# EditorConfig is awesome: https://EditorConfig.org

# top-most EditorConfig file
root = true

[*]
indent_style = space
indent_size = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = false
insert_final_newline = false
quote_type = single

After struggling with the issue I found a useful tool. If you click on the Prettier word in the right lower corner you will get the Output window opened. In that window once you run formatting (in my case it is Alt + Shift + F) you will see all the configurations which prettier will use to format the document. So, we can clearly see that specifying the prettier in the prettier.singleQuote is wrong. It should just be singleQuote. Hence, having the .prettierrc file in my user root folder with the following contents produced the desired result:

{
    "trailingComma": "none",
    "useEditorConfig": false,
    "singleQuote": true
}

此外，请确保已安装了Prettier扩展。

好吧，就像那个家伙(@user2982122)提到的，但不是文件，而是代码->首选项->设置，然后寻找引用，选择更漂亮，并勾选两个框

你可以在settings.json中使用它

"javascript.preferences.quoteStyle": "single"

我没有安装更漂亮的扩展，但在阅读可能重复的答案后，我从头开始添加在我的用户设置(用户设置。json, Ctrl+，快捷方式):

"prettier.singleQuote": true

部分有绿色警告(未知配置设置)，单引号不再被替换。

我怀疑更漂亮的扩展是不可见的，但嵌入在Vetur扩展。

看起来这个问题有一个漏洞:更漂亮的漏洞

以上方法对我都没用。 唯一有效的是，在package.json中添加这行代码:

"prettier": {
    "singleQuote": true
  },
