Question

我第一次使用Chalice，因为我正在尝试将其评估为将现有Python Flask API从EC2迁移到Lambda的可能替代框架。

在亚马逊Linux EC2实例中，我添加了一些依赖关系到我玩的virtualenv。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进行部署并获得：

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，我尝试关注docs的链接，并针对第一个有问题的依赖关系MySQL-python==1.2.5，我执行了以下操作：

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：

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

现在当我运行圣杯部署时，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

从文档中，我不清楚我做错了什么。有人可以帮忙吗？

Answer 1

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。把它放在您的供应商目录中。

Answer 2

您可以从requirements.txt中删除“ MySQL-python == 1.2.5”（因为它已经存在）出现在您的供应商目录中）
