使用这个扩展。

cmd ' (ctrl '在win/Linux上)将在' ' '中循环

这对我来说很管用: 尝试右键单击当前文档 然后选择format document with， 并为文档选择自己的格式扩展。 ：）

对于JSX使用:

{"jsxSingleQuote": false}

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。

对于默认使用.editorconfig文件的项目。格式化程序将忽略设置中的规则并使用.editorconfig中的规则，然后您可以:

删除.editorconfig文件，并使用VSCode设置。 根据您的文件类型，在.editorconfig文件中添加quote_type = single。也可以将quote_type value设置为double或auto。

在.prettierrc中添加

{
  "arrowParens": "avoid",
  "semi": false,
  "singleQuote": true
}
