openshift：无法为python应用程序安装lxml [英] openshift: can't install lxml for python app

问题描述

我正在尝试Openshift，但我无法使用 lxml 部署python应用程序。

以下是我的步骤，我只添加 lxml 要求。错误发生在我推送时。

我能够ssh，所以我不认为这是连接问题。

如果我不添加lxml要求，但添加了一些其他库，它可以工作。

问题仅在于lxml。我认为这是因为它具有一些系统依赖性（我必须在ubuntu机器上运行此命令： sudo apt-get install -y libxml2-dev libxslt-dev python-dev ）

然而我不认为我可以为openshift应用程序做这件事。有没有办法安装lxml呢？

命令

  rhc app创建testlxml python-3.3 
 echo'lxml'> testlxml / requirements.txt 
 cd testlxml 
 git add。 
 git commit -m添加lxml要求
 git push 
  

结果：

最新版本的 lxml （ 3.5.0 ）不起作用，但 lxml == 3.4.4 作品。
 
I am trying Openshift but I can't deploy a python app with lxml.

Below are my steps, I'm only adding a lxml requirement. The error happens when I push.

I am able to ssh so I don't think it's a problem of connectivity.

If I don't add the lxml requirement but add some other libraries, it works.

The problem is with lxml only. I think it's because it has some system dependencies (I have to run this on a ubuntu machine before: sudo apt-get install -y libxml2-dev libxslt-dev python-dev)

However I don't think I can do this for an openshift app. Is there no way to install lxml then?



Commands
rhc app create testlxml python-3.3
echo 'lxml' > testlxml/requirements.txt
cd testlxml
git add .
git commit -m "Add lxml requirement"
git push

warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.

In Git 2.0, Git will default to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)
