Question

我正在使用Jenkins构建一个python（Flask）解决方案来部署到Google App Engine。作为构建过程的一部分，我运行了一些集成测试。

其中一个失败，出现以下错误。

ERROR: Failure: ImportError (PyCapsule_Import could not import module "pyexpat")
----------------------------------------------------------------------
Traceback (most recent call last):

  File "/usr/lib/python2.7/xml/etree/cElementTree.py", line 3, in <module>

ImportError: PyCapsule_Import could not import module "pyexpat"

我已登录虚拟机并搜索此模块，这就是我得到的

xxx@jenkins-pre1:~$ sudo find / -name pyexpat*
/usr/lib/python2.7/lib-dynload/pyexpat.so
/var/lib/docker/aufs/diff/d0cfa9780fa540e496fd60e38f32c58708374a4a62bc8a6462834c7757a31cdf/usr/lib/python2.7/lib-dy
nload/pyexpat.x86_64-linux-gnu.so

我猜它的安装但无法导入模块。请帮忙。

模块位于python路径中。

>>> import sys
>>> print sys.path
['', '/usr/local/lib/python2.7/dist-packages/setuptools-15.2-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/no
se-1.3.6-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/pip-7.0.3-py2.7.egg', '/usr/lib/python2.7', '/usr/lib/

Answer 1

我找到了解决此问题的方法：

在你的jenkins脚本中，只需在开头清除LD_LIBRARY_PATH变量：

export LD_LIBRARY_PATH =＆＃34;＆＃34;

这就是诀窍!!

Answer 2

似乎/usr/lib/python2.7/lib-dynload/不在你的Python路径中。您可以使用以下Python命令进行检查：

import sys
print sys.path

如果没有出现，您可以设置PYTHONPATH环境变量：

$ export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/lib-dynload/

请务必检查PYTHONPATH环境变量是否为空，如果为空，请将sys.path的值分隔为“:”。

希望我帮助过。

Answer 3

使用gcc 5.4

在UBUNTU 16.04上安装caffe后出现此错误

这对我有用：

pip uninstall scikit-image

sudo apt-get install python-skimage

但是上面的另一台机器也无法解决这个问题：

这有效：

ldd /usr/lib/python2.7/lib-dynload/pyexpat.x86_64-linux-gnu.so 
    linux-vdso.so.1 =>  (0x00007fffa4570000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f3ff57dc000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f3ff5416000)
    libexpat.so.1 => /opt/oracle/product/11.2.0/dbhome_1/lib/libexpat.so.1 (0x00007f3ff52e5000)
    /lib64/ld-linux-x86-64.so.2 (0x00005645018a1000)
#and just rename that libexpat.so.1
cd /opt/oracle/product/11.2.0/dbhome_1/lib
sudo mv libexpat.so.1 libexpat.so.1.bak
