“abort: No module named selectors!” when Pushing Mercurial repository to Git repository

Question

I am trying to convert Hg repository to Git repository. Both are private repository.

I have followed these steps (reference):

• Step 1: Set up your repositories

• Step 2: Install the Mercurial hggit plugin

• Step 3: Push your code into your Git repository

• Step 4: Switch your local repository to use Git

I have installed the prerequisites also viz. hg-git plugin and updated the .hgrc file of the repository that needs to convert.

Error coming while pushing the repository( hg push [Git repo path] ) is "abort: No module named selectors!"

I have used --traceback option, please find the log below:

E:\BK_Hg\testHg>hg push --traceback https://[email protected]/CJbipin/testgit2.git

Answer 1

Because even in released THG 5.0.2 bundled hg-git sill have the same problem:

THG 5 solutions in details, step-by-step

Lazy fast way

• Download patched full lib for THG 4.9.1 from comment in BB's issue
• Replace dulwich + urllib3 in your THG's library archive by patched version from the above library
• If after it clone attempt of git-repo raised "urllib3.exceptions.MaxRetryError" error then remove certifi or use certifi from patch

Longer more pure way

• unpack library.zip
• replace urllib3 with 1.24.1 (download, compile, replace old *.pyo)
• replace dulwich with same content from https://github.com/dulwich/dulwich/, latest 0.19.11, (download, compile, replace old *.pyo)
• We have don't replace hg-git, because bundled hggit contains latest compatibility fixes for Mercurial 5 (while dmitriyse's version don't have yet)
• remove certify
• re-pack library
