Postgresql 将具有psycopg2依赖项的Flask应用程序部署到Elastic Beanstalk。ec2实例赢了'；t安装yum软件包

我在将flask应用程序部署到EB时遇到问题

我正在使用eb-cli。我已在应用程序的根文件夹中创建了一个.ebextensions文件夹。该文件夹包含两个文件：

00dependencies.config

packages:
  yum:
    libffi-devel : []
    postgresql95-devel: []

container_commands:
  00_wsgi_pass_headers:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'
option_settings:
  "aws:elasticbeanstalk:container:python":
    WSGIPath: "api-siifra/manage.py"
  "aws:elasticbeanstalk:container:python:staticfiles":
    "/static/": "api-siifra/app/static/"

01 setup.config

packages:
  yum:
    libffi-devel : []
    postgresql95-devel: []

container_commands:
  00_wsgi_pass_headers:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'
option_settings:
  "aws:elasticbeanstalk:container:python":
    WSGIPath: "api-siifra/manage.py"
  "aws:elasticbeanstalk:container:python:staticfiles":
    "/static/": "api-siifra/app/static/"

但是当我运行eb deploy时，我得到一个错误：

ERROR: Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.

/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1

在“运行状况”下查看eb web界面，我看到错误：

ERROR: Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.

/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1

命令在以下位置失败：错误：未找到pg_config可执行文件。安装psycopg2时

如果我通过ssh连接到有问题的ec2实例并手动安装postgresql95-devel，eb-deploy命令返回时没有错误

我想包：百胜。。。。在pip命令之前运行的*.config文件中

任何帮助都将不胜感激。

多谢各位
