导入错误：没有名为 boto3 的模块

Question

安装了 boto3 并将其升级到最新版本。我尝试了简易安装 pip 进行安装。我安装了多个版本的 python，所以我什至尝试在 virtualenv venv 中安装。但我得到了同样的错误：“没有名为 boto3 的模块”。

pip install boto3

python
Python 2.7.11 (default, Mar 10 2016, 14:12:44)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import boto3
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named boto3
>>>

我尝试使用 / 不使用 sudo：

sudo pip install boto3

我正在尝试在 Raspberry Pi 上安装 AWS SDK。

pip freeze

显示“boto3==1.3.0”已安装。

sudo pip install boto3

sudo pip install boto3 将其安装到您的全局 pip。此处解释：无法安装 boto3

您可以激活您的 venv，在没有 sudo 的情况下安装 boto3 并启动 python：

$ source path/to/your/ENV/bin/activate
$ pip install boto3
$ python

或者，如果您更喜欢使用全局安装，请执行以下操作：

$ deactivate
$ pip install boto3
$ python
