我正在尝试使用lxml提交POST方法表单,我得到一个TypeError.这是引发此错误的最小示例:

>>> import lxml.html
>>> page = lxml.html.parse("http://www.webcom.com/html/tutor/forms/start.shtml")
>>> form = page.getroot().forms[0]
>>> form.fields['your_name'] = 'Morphit'
>>> result = lxml.html.parse(lxml.html.submit_form(form))
    Traceback (most recent call last):
          File "<stdin>", line 1, in <module>
            File "/usr/lib/python3.3/site-packages/lxml/html/__init__.py", line 887, in submit_form
              return open_http(form.method, url, values)

建立

我写了一个小脚本来自动提取/提交/推送一些个人数据.这个脚本在我的笔记本电脑上很好用(版本1.8.3.2-1),但在我的服务器上,git pull命令失败了,信号13.我运行的是1.7.9.5-1版本(这些都是ubuntu,但是服务器是12.04.4 LTS vs 13.10在笔记本电脑上),我使用ppa:git-core repo将git更新为1.9.0-1~ppa0~precision1.这仍然会给我的脚本带​​来同样的问题.可能的复杂性是,笔记本电脑从服务器上的裸仓库通过ssh拉出,而服务器从同一个裸仓库(到其他地方的工作副本)拉出但不使用ssh,它只有本地路径.

问题

我可以使用以下命令在终端中重现该问题:

> git pull origin master | read msg; echo ${msg}
First, rewinding head to replay your work on top of it...
error: git-pull died of signal 13

这似乎是获取提交并检查它,但不更新主分支并使repo离开分支:

> git status
# Not currently on any branch.
nothing to commit (working directory clean)

切换回master会发出警告:

> git checkout master
Warning: you are leaving 1 commit behind, not connected to
any of your branches:
