【问题描述】：
我在 AWS Elastic Beanstalk 上部署 matplotlib 非常开心。 I gather 我的问题来自某些依赖项以及 EB 部署使用 PIP 安装的软件包的方式，并已尝试按照 instructions here on SO 解决问题。
我首先尝试按照链接答案中的建议逐步部署，方法是将 matplotlib 包堆栈的各个部分分阶段添加到我的 requirements.txt 文件中。但这需要 forever（对于每个阶段）并且容易出现故障和超时（这似乎会使构建目录落后于后续的软件包安装）。
所以答案末尾随便提到的简单解决方案对我很有吸引力：只需eb ssh，使用
source /opt/python/run/venv/bin/activate
和pip install 手动打包。但我也不能让它工作。首先，我经常遇到左侧构建目录（如上所述）
pip can't proceed with requirement 'xxxx' due to a pre-existing build directory.
location: /opt/python/run/venv/build/xxxx
This is likely due to a previous installation that failed.
pip is being responsible and not assuming it can delete this.
Please delete it and try again.
但即使在删除这些之后，我也一直得到 p>

响应pip install xxxx（并且sudo pip 失败并返回sudo: pip: command not found）。
我可以做些什么来让它在 AWS-EB 上运行？特别是，我需要做什么才能使简单的 SSH+PIP 方法正常工作；还是有其他更好的——更简单的！ — 我应该尝试的方法。
FWIW，我有一个 .ebextensions/software.config 和
packages:
yum:
gcc-c++: []
gcc-gfortran: []
python-devel: []
atlas-sse3-devel: []
lapack-devel: []
libpng-devel: []
freetype-devel: []
zlib-devel: []
还有一个以
结尾的requirements.txt
pytz==2014.10
pyparsing==2.0.3
python-dateutil==2.4.0
nose==1.3.4
six>=1.8.0
mock==1.0.1
numpy==1.9.1
matplotlib==1.4.2
大约 4 小时后，我已经达到了 numpy 的程度（由 EB virtualenv 中的pip list 报告）。
并且（如果重要的话）进行 SSH 的用户属于具有策略的组
