【中文标题】尝试使用弹性 beantalk 安装 libjpeg-devel 时出错

【英文标题】：Error trying to install libjpeg-devel with elastic beanstalk

【问题描述】：

我正在尝试在 AWS Elastic beanstalk 上运行的 Django 应用程序上调整图像大小，因此我正在尝试安装 Pillow 来完成这项工作。

正如之前的一些帖子所述，我正在添加

packages:
  yum:
    libjpeg-devel: '6b'

在我的 .ebextension/myapp.config 的顶部

我的 requirement.txt 包括：

Django==1.6.7
boto>=2.32.1
django-filter>=0.7
django-password-reset>=0.7
django-storages>=1.1.8
django-taggit==0.12
djangorestframework>=2.3.13
django-bootstrap3>=4.11.0
django-bootstrap3-datetimepicker>=2.2.3
python-dateutil>=2.2
pytz>=2014.2
six>=1.7.3
wsgiref==0.1.2
yolk==0.4.3
Pillow==2.5.3
googlemaps==1.0.2
mysql-python>=1.2.5

但是当我使用eb start 或git aws.push 时，我的弹性beantalk 日志中出现以下错误：

【参考方案1】：

我可以通过使用libjpeg-turbo-devel 软件包来安装它，而无需特定版本。 YAML 如下：

packages:
    yum:
        libjpeg-turbo-devel: []

如果您特别需要该版本，您可能需要研究 libjpeg-turbo 等效版本。

手动解决这些问题的一种方法是通过 SSH 连接到您环境中的实际实例或启动一个新实例。

在这种情况下，为了测试这一点，当我 SSH 进入并运行 yum 安装时，发生了这种情况：

[ec2-user@ip-xxx-xx-xx-xxx ~]$ sudo yum install libjpeg-devel
Loaded plugins: priorities, update-motd, upgrade-helper
Resolving Dependencies
--> Running transaction check
---> Package libjpeg-turbo-devel.x86_64 0:1.2.1-3.4.amzn1 will be installed
--> Finished Dependency Resolution

如您所见，它改为解析为 libjpeg-turbo-devel。

【讨论】：

我不得不终止并重新启动实例，但这运行良好。非常感谢！
