I was facing the same issue. I fixed it by adding :
我面临着同样的问题。我通过添加来修复它：
compile 'com.squareup.retrofit2:converter-gson:<latest-version>'

Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();

In Retrofit 2.0, Converter is not included in the package and when you are using Retrofit 2.0 Make Sure follow new URL pattern
在 Retrofit 2.0 中，转换器不包含在包中，当您使用 Retrofit 2.0 时，请确保遵循新的 URL 模式
Base URL: always ends with /
基本 URL：总是以 / 结尾
@Url: DO NOT start with /
@Url：不要以 / 开头
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();

In the latest Retrofit 2.0,you should import the latest version :
在最新的 Retrofit 2.0 中，您应该导入最新版本：
compile 'com.squareup.retrofit2:retrofit:2.0.0'
compile 'com.squareup.retrofit2:converter-gson:2.0.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0'
Be careful call baseUrl()，at v2.0,it should be end of "/",and at the method ,you would't start thr url with"/"
小心调用baseUrl()，在v2.0，它应该以“/”结尾，并且在方法中，你不会以“/”开始thr url
@POST("classes/info")
Call<ContactBean> insertInfo(@Body ContactBean bean);
And you can see Retrofitto get more info! Hope help !
您可以查看Retrofit以获取更多信息！希望有帮助！

Then add
然后加

.baseUrl(Constants.API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();

In my case(Kotlin with coroutines) I received the exception:
在我的情况下（带有协程的 Kotlin），我收到了异常：
Unable to create converter for retrofit2.Call
for method Queries.exportPdf.
Caused by: java.lang.IllegalArgumentException: Could not locate ResponseBody converter for retrofit2.Call
无法为改造 2.Call 创建转换器
对于方法 Queries.exportPdf。
引起：java.lang.IllegalArgumentException：无法找到retrofit2.Call的ResponseBody转换器
A problem was in a request:
一个请求出现问题：
@FormUrlEncoded
@Streaming
@POST("export-pdf/")
suspend fun exportPdf(
@Field("token") token: String
): Call<ResponseBody>
Removed suspendfrom definition and exceptions disappeared.
suspend从定义中删除，异常消失。
