# AWS CLI バージョンアップでエラー発生を解消

## AWS CLI バージョンアップでエラー発生を解消

```
$ pip install awscli --upgrade --user
:
OSError: [Errno 13] Permission denied: '/Users/hayshogo/Library/Python/2.7/lib'
```

pipのインストールでエラー

```
$ sudo easy_install pip
TEST FAILED: /lib/python2.7/site-packages/ does NOT support .pth files
error: bad install directory or PYTHONPATH
```

```
$ cat ~/.pydistutils.cfg 
[install]
prefix=
```

空のprefixを.pydistutils.cfgで定義したのでこれを除去

```
$ rm ~/.pydistutils.cfg                                       
$ sudo easy_install pip                                    
```

```
$ aws -v
:
ImportError: No module named colorama
```

HomeBrewでインストールしたPython削除

```
$ brew uninstall python
```

デフォルトでインストールされているPythonが使われていることを確認

```
$ python --version
Python 2.7.10
$ which python
/usr/bin/python
```

PyenvでPythonをインストール

```
$ brew install pyenv-virtualenv
$ vim ~/.zshrc
```

以下を追記

```
export PYENV_ROOT=${HOME}/.pyenv
if [ -d "${PYENV_ROOT}" ]; then
    export PATH=${PYENV_ROOT}/bin:$PATH
    eval "$(pyenv init -)"
    eval "$(pyenv virtualenv-init -)"
fi
```

```
$ source ~/.zshrc
```

Pythonのバージョンをインストール

```
$ pyenv install -l
Available versions:
  2.1.3
  2.2.3
  2.3.7
:
:
  stackless-3.4.7
  stackless-3.5.4
$ pyenv versions
$ pyenv install 2.7.14
$ pyenv install 3.6.4
$ pyenv versions
* system (set by /Users/hayshogo/.pyenv/version)
  2.7.14
  3.6.4
```

目的のPythonのバージョンに切り替え

```
$ pyenv global 2.7.14
$ python -V
Python 2.7.14
```

```
$ pip uninstall pip
$ easy_install pip
$ pip -V
pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)
$ pip uninstall awscli
$ aws --version
zsh: /usr/local/bin/aws: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory
$ pip install awscli --upgrade --user
OSError: [Errno 13] Permission denied: '/Users/hayshogo/Library/Python/2.7/lib'
$ pip install awscli
$ aws --version
aws-cli/1.14.53 Python/2.7.14 Darwin/16.7.0 botocore/1.9.6
```

## 通常は以下のようにアップグレード可能

```
$ sudo -H pip install -U pip
$ sudo -H pip install -U awscli
$ aws --version
aws-cli/1.16.67 Python/2.7.15 Darwin/16.7.0 botocore/1.12.57
```
