为什么在使用pip安装软件包时出现无效的语法错误

Question

在Debian服务器中，当我使用pip安装boto3时，出现以下错误：

$ python3.2 -m pip install boto3

Traceback (most recent call last):

return u"".join(u"\\x%x" % c for c in raw_bytes), err.end

             ^
SyntaxError: invalid syntax

注意：点子版本为18.1

我想到了。 语法-u“”。join在python3.2中不受支持。

pip3（与pip3.2相同）在运行安装boto3的脚本时遇到了语法并引发了异常。

我安装了python 3.6，并在运行“ pip3.6 install boto3”时成功了。

注意：我的python项目是一个新的小型项目，因此从python3.2更改为python3.6并没有太大影响，但是对于大型项目或现有项目，这可能不可行。 只希望任何可能遇到这种情况的人都知道导致此问题的原因。
