【问题描述】：
我正在尝试在 Gatling 3.4.1 下使用 nothingFor 函数运行模拟。但是，编译失败并出现错误could not find implicit value for evidence parameter of type io.gatling.core.controller.inject.InjectionProfileFactory[Product with Serializable]
模拟
package abs
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._
class DefaultSimulation extends Simulation {
...
val httpProtocol = http
.baseUrl(Setting.baseUrl)
.userAgentHeader("Gatling/3.4.1")
setUp(
getScenario.inject(
nothingFor(20 seconds),
rampConcurrentUsers(0) to(20) during(10 seconds),
constantConcurrentUsers(20) during (600 seconds)
),
setScenario.inject(
rampConcurrentUsers(0) to(20) during(30 seconds),
constantConcurrentUsers(20) during (600 seconds)
)
).protocols(httpProtocol)
}
编译错误

我试图隐式指定导入，但编译失败并出现同样的异常
import io.gatling.core.Predef.{nothingFor, rampConcurrentUsers, constantConcurrentUsers, _}
此模拟在没有nothingFor(20 seconds) 的情况下编译和工作。
