Gradle DSL方法未找到：'implementation()'

我遇到了这个错误

Error:(45, 0) Gradle DSL method not found: 'implementation()'
Possible causes:
The project 'LaTaxi2' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 2.3.3 and sync project
The project 'LaTaxi2' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file
The build file may be missing a Gradle plugin.
Apply Gradle plugin
