问题描述
我正在尝试使用 express-validator 的保释函数在先前的验证失败时返回验证链实例。但是，保释函数被标识为属于@jest/types 的保释函数。见下图：
"C:\Program Files\nodejs\node.exe" C:\dev\Home-Together-Canada\server\bin\www
C:\dev\Home-Together-Canada\server\controllers\validators\userControllerValidator.js:68
.exists().bail()
^
TypeError: body(...).exists(...).bail is not a function

我如何指示 express-validator 使用它自己的保释函数而不是 jest 的？
