Cloning github repo with hggit

问题:

I am trying to clone some github repos locally with hggit. I am following tutorial instructions to do

$ hg clone git://github.com/schacon/hg-git.git
abort: repository git://github.com/schacon/hg-git.git not found!

$ hg clone git+ssh://[e-mail]/schacon/hg-git.git
abort: repository git+ssh://[e-mail]/schacon/hg-git.git not found!

I know I have hggit because the following works

$ python -c "import hggit"
$ head -n1 `which hg`
#!/opt/local/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python
$ /opt/local/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python -c "import hggit"

Also, I have another github repo that I regularly use with hg. I forgot how I initially got it to work, but I think it was a fresh repo that I pushed into github. In the folder where I do have a working repo, I have the following (paraphrased for privacy) in my .hg/hgrc:

github = git+ssh://[e-mail]:myname/repo.git

[ui]
username = Fname Lname <[e-mail]>

[extensions]
hgext.bookmarks =
hggit =

but of course there is no hgrc for the repo that I am just trying to clone.

Using additional features

    Mercurial has the ability to add new features through the use of extensions. Extensions may add new commands, add options to existing commands, change the default
    behavior of commands, or implement hooks.

    Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage only; they may provide
    potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime time; or they may alter some usual behaviors of
    stock Mercurial. It is thus up to the user to activate extensions as needed.

    To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your configuration file, like this:

      [extensions]
      foo =

    You may also specify the full path to an extension:

      [extensions]
      myfeature = ~/.hgext/myfeature.py

    To explicitly disable an extension enabled in a configuration file of broader scope, prepend its path with !:

      [extensions]
      # disabling extension bar residing in /path/to/extension/bar.py
      bar = !/path/to/extension/bar.py
      # ditto, but no path was supplied for extension baz
      baz = !

    disabled extensions:

     acl         hooks for controlling repository access
     bookmarks   track a line of development with movable markers
     bugzilla    hooks for integrating with the Bugzilla bug tracker
     children    command to display child changesets
     churn       command to display statistics about repository history
     color       colorize output from some commands
     convert     import revisions from foreign VCS repositories into Mercurial
     eol         automatically manage newlines in repository files
     extdiff     command to allow external programs to compare revisions
     fetch       pull, update and merge in one command
     gpg         commands to sign and verify changesets
     graphlog    command to view revision graphs from a shell
     hgcia       hooks for integrating with the CIA.vc notification service
     hgk         browse the repository in a graphical way
     highlight   syntax highlighting for hgweb (requires Pygments)
     interhg     expand expressions into changelog and summaries
     keyword     expand keywords in tracked files
     mq          manage a stack of patches
     notify      hooks for sending email notifications at commit/push time
     pager       browse command output with an external pager
     parentrevspec
                 interpret suffixes to refer to ancestor revisions
     patchbomb   command to send changesets as (a series of) patch emails
     progress    show progress bars for some actions
     purge       command to delete untracked files from the working directory
     rebase      command to move sets of revisions to a different ancestor
     record      commands to interactively select changes for commit/qrefresh
     relink      recreates hardlinks between repository clones
     schemes     extend schemes with shortcuts to repository swarms
     share       share a common history between several working directories
     transplant  command to transplant changesets from another branch
     win32mbcs   allow the use of MBCS paths with problematic encodings
     win32text   perform automatic newline conversion
     zeroconf    discover and advertise repositories on the local network

Update: Fix So the problem was that I did not have a '$HOME/.hgrc' file to use the extensions. Once I added this file and the extension information, everything worked fine!

回答1:

Here is a thought, maybe its not fully installed. I have had similar problems and found compiling it manually instead of using 'easy_install' to work better. I had problems where the version of 'dulwhich' wasn't installed properly, so things were broken (probably similarly to yours).

I outlined the installation process here on my blog -> http://andypeters.org/post/5607486048/hg-git-installation-woes-on-a-mac

Here is a quick summary for installation.

1. Download. I have been using 0.7.

2. Install dulwich. Notice the use of --pure. I'm not 100% sure what that means, but my understanding is that it is a python thing to make a different/clean install of it.

   > sudo python setup.py --pure install
   

3. Download hg-git. I have linked to bitbucket because i assume you have mercurial working.

4. Install hg-git

   > sudo python setup.py install
   

Hope that helps.

回答2:

On a Debian-based GNU/Linux distribution, in addition to

$ sudo apt-get install mercurial-git

I had to add the following lines to my ~/.hgrc file:

[extensions]
hggit = /usr/share/pyshared/hgext/git

回答3:

my config on ubuntu 14.04 (cf /usr/share/doc/mercurial-git/README.Debian from package mercurial-git):

[extensions]
hgext.bookmarks =
hgext.git = 

The file to add this is : ~/.hgrc

回答4:

To enable hg-git (note the '-') in mercurial, you need something like:

[extensions]
hg-git=e:\hg-extensions\hg-git\hggit
