raspberry-pi2 - 导入错误 : No module named boto3

Question

安装 boto3 并将其升级到最新版本。我尝试了easy install 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

显示已安装“boto3==1.3.0”。

sudo pip install boto3

Answer 1

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