我正在尝试部署Flask应用。当我做eb deploy时，出现以下错误消息：

检查eb logs后，我发现问题出在尝试安装scipy时：

我对MemoryError进行了一些研究，似乎可以使用命令行参数--no-cache-dir来解决问题。我创建了一个名为.ebextensions的文件夹，并创建了一个名为.config的{{1}}文件，其中包含：
python.config我认为这可以某种方式配置部署，因此它使用no cache选项调用pip install。但是，这是一种忽略，因为根据日志，没有使用命令行，因此我假设我的配置文件被忽略了。
我正在使用AWS免费套餐，这是我的commands:
01_no_cache:
command: /opt/python/run/venv/bin/pip install -r --no-cache-dir /opt/python/ondeck/app/requirements.txt
