圣杯包装问题

Question

我第一次尝试使用Chalice，因为我试图将它作为一个可能的替代框架来评估，以便将我现有的Python Flask api从EC2迁移到Lambda。在

从AmazonLinuxEC2实例中，我向正在使用的virtualenv添加了一些依赖项。然后我创建了一个要求.txt公司名称：

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，得到：

^{pr2}$

然后，我尝试遵循链接的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.

Your deployment will continue but may not work correctly
if missing dependencies are not present. For more information:

从文件上看，我不清楚我做错了什么。有人能帮忙吗？在

Answer 1

您可以从要求.txt（既然已经 存在于供应商目录中）

更多信息请参见圣杯回购中的issue。在

Answer 2

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。把它放到你的供应商目录里。在
