任何想法？非常感谢

Answer 1

尝试此解决方案：https://pkimber.net/howto/python/pip/install-modules.html

激活你的python虚拟环境......

构建并安装：

$ wget ftp://xmlsoft.org/libxml2/libxml2-2.9.1.tar.gz
$ tar xf libxml2-2.9.1.tar.gz
$ cd libxml2-2.9.1
$ ./configure
$ make
$ cd python
(virtenv)$ python setup.py install

Answer 2

sudo apt-get install libxslt1-dev

Answer 3

这可能是由于libxml2-python与系统libxml2和libxslt1.1之间的版本不匹配。

最近，我在Ubuntu Trusty（14.04）上安装libxml2-python-2.6.21时遇到了同样的问题。我发现绑定取决于libxml2版本 2.7.8 和libxslt1.1版本 1.1.26 。但该版本分别在版本 2.9.1 和 1.1.28 上有libxml2和libxslt1.1。

我有两种方法可以解决这个问题：

从来源[0]构建libxml2和libxslt1.1。

# update system
apt-get -y -qq --force-yes update

# install needed system deps
apt-get -y -qq --force-yes install \
    python-setuptools \
    build-essential \
    wget \
    python-dev \
    zlib1g-dev

# download libxml2 and libxslt1.1
mkdir /opt/src \
    && cd /opt/src \
    && wget ftp://xmlsoft.org/libxml2/libxml2-2.7.8.tar.gz \
    && wget ftp://xmlsoft.org/libxslt/libxslt-1.1.26.tar.gz \
    && tar -xzf libxml2-2.7.8.tar.gz \
    && cd /opt/src/libxml2-2.7.8 \
        && ./configure && make && make install \
    && cd /opt/src \
    && tar -xzf libxslt-1.1.26.tar.gz \
    && cd /opt/src/libxslt-1.1.26 \
        && ./configure && make && make install \
    && ldconfig -v

# install pip
easy_install pip

# install offending package
wget ftp://xmlsoft.org/libxml2/python/libxml2-python-2.6.21.tar.gz
pip install libxml2-python-2.6.21.tar.gz

# install othe package that depends upon libxml2 and libxslt1.1
pip install lxml

使用来自Ubuntu Precise源[1]的libxml2和libxslt1.1。

# enable precise source
echo "deb http://archive.ubuntu.com/ubuntu precise main universe" \
    >> /etc/apt/sources.list

# update system
apt-get -y -qq --force-yes update \

# install needed deps
apt-get -y -qq --force-yes install \
    python-setuptools \
    build-essential \
    wget \
    python-dev \
    libxml2/precise \
    libxml2-dev/precise \
    libxslt1.1/precise \
    libxslt1-dev/precise \
    zlib1g-dev

# install package that depends upon libxml2 and libxslt1.1 to show that both
# will not be upgraded
apt-get -y -qq --force-yes install \
    libxmlsec1 \
    libxmlsec1-dev \
    libxmlsec1-openssl

# install pip
easy_install pip

# install offending package
wget ftp://xmlsoft.org/libxml2/python/libxml2-python-2.6.21.tar.gz
pip install libxml2-python-2.6.21.tar.gz

# install other binding that depends on libxml2 and libxslt1.1
pip install lxml

嗯，希望它可以帮到你。
