ImportError:PyCapsule_Import无法导入模块"pyexpat"

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")
----------------------------------------------------------------------

ImportError: PyCapsule_Import could not import module "pyexpat"

我已经登录到虚拟机并搜索了这个模块,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

我想它的安装,但模块无法导入.请帮忙.

该模块位于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

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 =""

这样做的伎俩!!

Answer 2

看来这/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，可以设置PYTHONPATH环境变量：

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

请务必检查环境变量是否为空，如果为空，请将“ ”分隔PYTHONPATH的值复制到其中。sys.path:

希望我有所帮助。
