当我尝试安装时odoo-server,出现以下错误:

error: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

谁能帮我解决这个问题？

我在安装时遇到问题lxml.我已尝试过本网站和其他网站的相关问题的解决方案,但无法解决问题.需要一些建议/解决方案.

我在执行后提供完整的日志pip install lxml,

我在尝试将"pip install lxml"运行到Ubuntu 12.10 x64中的virtualenv时遇到以下错误.我有Python 2.7.

我在这里看到了有关同一问题的其他相关问题,并尝试安装python-dev,libxml2-dev和libxslt1-dev.

请看一下从命令提示到错误发生的那一刻的追溯.

我正在尝试安装libxml2,以便我可以设置python绑定并最终使用lxml.

但是,我无法在地球上工作,我应该解压缩文件.我没能成功谷歌.

我是否需要Cygwin/MinGW才能使安装成功？

目前,我将libxml2.tar.gz和libxslt.tar.gz中的文件放在Python文件夹中各自的目录中.因此,包含在包含的变量中的文件位于Python26\include\libxml2\libxml ...等等.

但是,当我运行easy_install lxml时,我收到以下输出:

已经尝试过以下帖子中的解决方案,但它没有用:

pip install lxml错误

当我sudo pip install pyquery,sudo pip install lxml和sudo pip install cython,我得到非常相似的输出与相同的错误说:

x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-fstack-protector-strong’

这是完整的点子输出sudo pip install pyquery:

我正在使用py测试诱惑适配器并尝试生成诱惑报告所需的输入数据.但我无法生成任何XML.当我使用py.test sample.py执行py文件时,它确实创建了pycache目录.然后我执行了"诱惑生成-v 1.3.9 C:\ allurereports"(这是我有sample.py的目录).它确实创建了一个诱人的HTML报告,但没有测试用例是0.没有详细信息.

sample.py(与示例中给出的相同)

import allure


@allure.feature('Feature1')
@allure.story('Story1')
def test_minor():
    assert False


@allure.feature('Feature2')
@allure.story('Story2', 'Story3')
@allure.story('Story4')
class TestBar:

    # will have 'Feature2 and Story2 and Story3 and Story4'
    def test_bar(self):
        pass

这是使用的py.test命令:py.test sample.py --allure_features = feature1,feature2

任何人都可以帮助我如何从文件中生成一个诱惑报告.有哪些命令要执行.

我有一个大约 30MB 的 XML 文件，里面有大约 300000 个元素。

我使用以下代码来处理这个文件。

xmldoc=xml.dom.minidom.parse("badges.xml")

csv_out=open("badge.csv","w")

for badge in xmldoc.getElementsByTagName("row"):
    some processing here
    csv_out.write(line)

该文件只有 30MB，但是当我在我的 MBP（10.7，8G RAM）上运行这个脚本时，它使用了将近 3GB 的内存。为什么这么简单的脚本和这么小的文件要占用这么多内存？

此致，
