我知道这已经很老了，但如果其他人来这里寻找答案，问题可能是 kafka-console-consumer.bat 是空的，因为它对我来说是空的.我在做

I know this is very old but in case someone else comes in here looking for an answer, the issue could be that kafka-console-consumer.bat is empty as it was for me. I was doing

.\bin\windows\kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic myTopic

并且命令行中不会发生任何事情，就像问这个问题的人一样，直到我发现我尝试运行的脚本文件中没有任何内容.我找到了其他人，他们的内容完好无损，只是复制并粘贴了内容.

and nothing would happen in the command line, same as to the person who asked this question, until I figured out the script file I'm trying to run has nothing in it. I found someone else who had theirs intact and just copied and pasted the contents in.

我不明白这个文件是怎么变空的，但在某些时候，我删除了它并尝试了很多方法来解决这个问题后，我无法发布一个主题，也许这是在不知何故的时候脚本文件被清除.

I don't understand how this file got empty but at some point, I couldn't get a topic to be released after I had deleted it and had tried a lot of things to fix this and perhaps this is when somehow that script file got cleared out.
