我有一个Django应用程序，它已部署到Amazon Elastic Beanstalk(Python 3.7 running on 64bit Amazon Linux 2/3.0.3)。我通过在.ebextensions文件夹中创建10_anaconda.config文件安装了anaconda和pythonocc-core软件包。
10_anconda.config；
commands:
00_download_conda:
command: 'wget https://repo.anaconda.com/archive/Anaconda3-2020.02-Linux-x86_64.sh'
01_install_conda:
command: 'bash Anaconda3-2020.02-Linux-x86_64.sh -b -f -p /anaconda'
02_conda_install_pythonocc:
command: '/anaconda/bin/conda install -y -c dlr-sc pythonocc-core=7.4.0'
然后，我在我的一个应用程序中创建了一个文件夹，并在该文件夹中创建了__init__.py和cadLoader.py文件。我已经将anaconda路径添加到__init__.py，它位于cad文件夹中；
import sys
sys.path.append('/anaconda/lib/python3.7/site-packages')
我已经将导入行添加到cadLoader.py中进行尝试；
import os
from OCC.Extend.DataExchange import read_stl_file
from OCC.Display.SimpleGui import init_display
from OCC.Core.GProp import GProp_GProps
from OCC.Extend.DataExchange import read_step_file
from OCC.Extend.DataExchange import read_iges_file
from OCC.Core.Bnd import Bnd_Box
from OCC.Core.BRepMesh import BRepMesh_IncrementalMesh
from OCC.Core.BRepBndLib import brepbndlib_Add
from OCC.Core.BRepGProp import brepgprop_VolumeProperties
当我将它部署到Elastic Beanstalk时，我得到了下面的错误行。
from data.modellib.cad.cadLoader import CADLoader
File "/var/app/current/data/modellib/cad/cadLoader.py", line 2, in <module>
from OCC.Extend.DataExchange import read_stl_file

from . import _XCAFDoc
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
根据这个问题，我添加了一个用于安装libGL的.config文件，如下所示：
packages:
yum:
mesa-libGL : []
mesa-libGL-devel : []
为了解决version ZLIB_1.2.9 not found错误，我添加了一个如下所示的配置文件。
commands:
00_download_zlib:
command: 'wget https://github.com/madler/zlib/archive/v1.2.9.tar.gz'
01_open_zlib:
command: 'tar xzvf v1.2.9.tar.gz'
02_into_zlib:
command: 'cd zlib-1.2.9'
03_make_zlib:
command: 'make'
04_make_install_zlib:
command: 'make install'
05_libz_so:
command: 'ln -fs /usr/local/lib/libz.so.1.2.9 /lib64/libz.so'
06_libz_so_1:
command: 'ln -fs /usr/local/lib/libz.so.1.2.9 /lib64/libz.so.1'
但是由于make命令，我的部署失败了。这是我的错误信息：
Unhandled exception during build: Command 03_make_zlib failed
Traceback (most recent call last):
File "/opt/aws/bin/cfn-init", line 171, in <module>

如何解决此问题并在我的应用程序中使用OCC程序包？
/lib64/libz.so.1:ZLIB_1.2.9版本未找到
AmazonLinux2提供1.2.7:版本
Name : zlib
Arch : i686
Version : 1.2.7
Release : 18.amzn2
Size : 91 k
Repo : amzn2-core/2/x86_64
Summary : The compression and decompression library

Description : Zlib is a general-purpose, patent-free, lossless data compression
: library which is used by many different programs.
您可以尝试手动将zlib升级到1.2.9，例如以root身份执行以下步骤(如果它们有效，您可以通过.ebextentions自动执行(：
wget https://github.com/madler/zlib/archive/v1.2.9.tar.gz
tar xzvf v1.2.9.tar.gz
cd zlib-1.2.9
./configure
make
make install
ln -fs /usr/local/lib/libz.so.1.2.9 /lib64/libz.so
ln -fs /usr/local/lib/libz.so.1.2.9 /lib64/libz.so.1
这必须经过仔细测试，因为手动升级可能会破坏一切。这里还有其他一些升级选项。
