将lxml.etree导入python时出错-Java 学习之路

我在我的mac上安装了一个lxml，当我输入这样的python时

localhost:lxml-3.0.1 apple$ python

我有同样的问题 . 如果您使用pip安装它，如下所示： pip install lxml

相反，尝试使用
```
STATIC_DEPS=true pip install lxml
```
这解决了我的问题 .

如果您已经安装了 libxml2 ，那么's possible that it'只是没有选择正确的版本（'s a version installed with OS X by default). In particular, suppose you'已安装 libxml2 到 /usr/local . 您可以查看共享库 etree.so 引用的内容：

$> otool -L /Library/Python/2.7/site-packages/lxml-3.2.1-py2.7-macosx-10.7-intel.egg/lxml/etree.so 
/Library/Python/2.7/site-packages/lxml-3.2.1-py2.7-macosx-10.7-intel.egg/lxml/etree.so:
    /usr/lib/libxslt.1.dylib (compatibility version 3.0.0, current version 3.24.0)
    /usr/local/lib/libexslt.0.dylib (compatibility version 9.0.0, current version 9.17.0)
    /usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.3.0)
    /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

在系统安装的版本中检查该符号：

$> nm /usr/lib/libxml2.2.dylib | grep ___xmlStructuredErrorContext

对我来说，它不存在于系统安装的库中 . 但是，在我安装的版本中：

$> nm /usr/local/lib/libxml2.2.dylib | grep ___xmlStructuredErrorContext
000000000007dec0 T ___xmlStructuredErrorContext

要解决此问题，请确保您的安装路径首先出现在 DYLD_LIBRARY_PATH 中：

$> export DYLD_LIBRARY_PATH=/usr/local/lib
$> python
>>> from lxml import etree
# Success!

运行以下命令以安装lxml软件包 .
```
pip install lxml --user
```
应该解决这个问题 . 我在MAC OSX 10.7.5上测试过，它工作正常 .
