python - chalice 包装问题

Question

我正在玩弄 Chalice这是我第一次尝试将其评估为可能的替代框架，以将我现有的 Python Flask API 从 EC2 迁移到 Lambda。

我从一个 Amazon Linux EC2 实例向我正在使用的 virtualenv 添加了一些依赖项。然后我创建了一个 requirements.txt:

botocore==1.7.11
chalice==1.0.2
click==6.6
docutils==0.14
jmespath==0.9.3
MySQL-python==1.2.5
PyMySQL==0.7.11
python-dateutil==2.6.1
six==1.10.0
SQLAlchemy==1.1.14
typing==3.5.3.0

然后我尝试使用 chalice deploy 进行部署并得到:

Creating deployment package.

Could not install dependencies:
MySQL-python==1.2.5
typing==3.5.3.0
You will have to build these yourself and vendor them in
the chalice vendor folder.

Your deployment will continue but may not work correctly
if missing dependencies are not present. For more information:
http://chalice.readthedocs.io/en/latest/topics/packaging.html
........

然后我尝试跟踪链接 docs对于第一个有问题的依赖项 MySQL-python==1.2.5 我做了以下操作:

cd vendor/
pip download MySQL-python==1.2.5
pip wheel MySQL-python-1.2.5.zip
rm rm MySQL-python-1.2.5.zip 
unzip MySQL_python-1.2.5-cp27-cp27mu-linux_x86_64.whl 
rm MySQL_python-1.2.5-cp27-cp27mu-linux_x86_64.whl

我的供应商文件夹如下所示:

ls vendor
MySQLdb  _mysql_exceptions.py  MySQL_python-1.2.5.dist-info  _mysql.so

现在，当我运行 chalice deploy 时，我得到:

(test)[ec2-user@ip-172-31-26-155 test]$ chalice deploy
Creating deployment package.

Could not install dependencies:
MySQL-python==1.2.5
You will have to build these yourself and vendor them in
the chalice vendor folder.

根据文档，我不清楚我做错了什么。有人可以帮忙吗？

查看您提供的目录列表中的内容，我注意到您没有 init.py 文件。此文件将文件夹标识为库文件。将其放入您的供应商目录中。
