windows上的subrepos出现Mercurial错误

Question

我对配置了传票的Mercurial有严重的问题。当我尝试提交或进行更新时，我得到以下错误：

hg commit -m "commit" --traceback
Traceback (most recent call last):
File "mercurial\dispatch.pyc", line 87, in _runcatch

我的.hgsub：

webdriver/vendor/webdriver = [svn]http://php-webdriver-bindings.googlecode.com/svn/trunk/trunk/phpwebdriver/
app/vendor/bundles/Knp/Bundle/ZendCacheBundle = [git]http://github.com/knplabs/KnpZendCacheBundle.git
app/vendor/Zend/Cache = [git]http://github.com/knplabs/zend-cache.git
app/vendor/Zend/Filter = [git]http://github.com/knplabs/zend-filter.git

我使用的是Windows XP和Mercurial 1.9.2。我在PATH中添加了svn和git，它工作得很好。当我尝试手动更新我的传票时，没有问题，svn up和git pull工作得很好。

Answer 1

如果path中的Git for Windows (mysysgit)目录为C:\Program Files (x86)\Git\cmd，请尝试将其更改为：

C:\Program Files (x86)\Git\bin

这将使git能够与Mercurial一起工作。

Answer 2

要调试路径问题，可以使用以下文件

# qnddebug.py
import os
import sys
import subprocess

print os.environ['PATH']
print subprocess.call(['git', '--version'])
sys.exit(23)

并用hg --config extensions.foo=qnddebug.py运行它。然后，您可以在第一行看到mercurial使用哪个路径来查找程序。最后一行是git调用的错误代码，必须为0。可能在退出状态之前的行中有git --version的输出，但这是特定于平台的详细信息。
