Question

我试图安装烧瓶问模块在我的树莓派这是运行raspberrian-noobs。我使用pip命令"pip3安装烧瓶-问"然后它正在经历下载过程，当它试图安装模块时，我得到

错误：异常信息：Traceback（最近的调用最后）：File"/usr/lib/python2.7/dist-包/pip/basecommand.py"，第122行，在

在运行pip安装之前，我尝试过运行pip安装加密，但发现错误：

Exception information:

    status = self.run(options, args)

我还试着下载tar。gz文件手动形成pypi网站，但这以相同的错误结束。

在Pi上，我升级了pip3后运气更好了。试试看

sudo -H pip3 install --upgrade pip

然后再次尝试安装。
