AWS EB CLI安装失败，显示“ python setup.py egg_info”失败，错误代码为“ 1”

我试图像这样在virtualenv中安装awsebcli：

pip install awsebcli --upgrade --user

安装失败，并出现以下错误：

 Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-dpxu8m6m/awsebcli/setup.py", line 48, in <module>

注意：这个问题的答案都没有-PIP安装Numpy会引发错误“ ascii编解码器无法解码字节0xe2”。
