[AWS] Problem avoidance memo when installing awscli and boto3 in Python 2.7 environment

Introduction

The Python version of AWS Lambda is Python 2.7. This is a workaround memo when installing awscli and boto3 in Windows Anaconda environment and Python 2.7 environment. There are two problems to avoid.

1. The awscli, boto3 package for win-64 cannot be found (occurs in Windows Anaconda environment)

   > conda install awscli
   PackageNotFoundError: Package not found: '' Package missing in current win-64 channels:
     - awscli
   
   > conda install boto3
   PackageNotFoundError: Package not found: '' Package missing in current win-64 channels:
     - boto3
   

2. Unicode Warning (occurs in Python 2.7 environment) Command example

   > aws s3 ls s3://<bucket_name>
   

Unicode Warning that occurs in Anaconda2 environment

```
Anaconda2\lib\site-packages\dateutil\parser.py:605: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
  elif res.tzname and res.tzname in time.tzname:
```

Unicode Warning that occurs in the environment where AWS CLI is installed by msi

```
C:\Program Files\Amazon\AWSCLI\.\dateutil\parser.py:601: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
```

Install awscli

For Windows environment, specify conda-forge.

> conda install -c conda-forge awscli

installation of boto3

For Windows environment, specify conda-forge.

> conda install -c conda-forge boto3

Check the installation status

• Anaconda3

  > aws --version
  aws-cli/1.10.44 Python/3.5.2 Windows/10 botocore/1.4.34
  

• Anaconda2

  > aws --version
  aws-cli/1.10.44 Python/2.7.12 Windows/10 botocore/1.4.34
  

• For the aws command, the path must be in the Scripts folder of Anaconda.

Interim measures for Unicode Warnings that occur in the Python 2.7 environment

This is a temporary measure, but it suppresses ʻUnicode Warning`.

• aws command Anaconda2 \ Scripts \ aws.cmd Specify -W ignore :: UnicodeWarning on line 19.

  %PythonExe% -x %PythonExeFlags% "%~f0" %*
  

  %PythonExe% -W ignore::UnicodeWarning -x %PythonExeFlags% "%~f0" %*
  

• If AWSCLI64.msi is installed, uninstall AWSCLI64.msi.

• python command Specify -W ignore :: UnicodeWarning. Example of running the Boto sample

  > python -W ignore::UnicodeWarning .\s3_sample.py
  

• IPython Run the Unicode Warning suppression script when IPython starts. ~/.ipython/profile_default_startup or <user_home>\.ipython\profile_default\startup

  import warnings
  warnings.filterwarnings('ignore', category=UnicodeWarning)
