running go mod tidy or make project1 gives me an error

[mdlfop]

go version go1.14.3 linux/amd64
I receive the following error when I run any of the above commands:

go: github.com/pingcap/tidb@v1.1.0-beta.0.20200309111804-d8264d47f760 requires

can't reproduce, are you sure it's the latest course branch?

[mdlfop]

Yes. I am on the latest commit on the course branch. I also tried on another computer and I still receive the same error message. Thanks. The error message when I run make project1:

GO111MODULE=on go test -v --count=1 --parallel=1 -p=1 ./kv/server -run 1

github.com/pingcap/tidb@v1.1.0-beta.0.20200309111804-d8264d47f760 seems an old version, not the same as the one in the latest commit.

Thanks @Connor1996 . I still believe I am using the latest commit of the branch. I have created a google colab notebook showing the things I have done. Please take a look at it. (I still get the same errors here as well) https://colab.research.google.com/drive/16dSBPQ4ekB2e0nCQn4xjhJSwQSl0uBdi?usp=sharing

[Connor1996]

You're right. It's due to the modcache. After running go clean -modcache, I can reproduce it. Let me take a look.

[Connor1996]

Fix it. Please try again.

It works! Thanks a lot :)
