在Raspberry Pi上安装Flask-ask

我试图在正在运行raspberrian-noobs的Raspberry Pi上安装"flask-ask" module。我使用PIP命令"pip3 install flask-ask" 然后它会通过下载过程，当它试图安装模块我得到的在Raspberry Pi上安装Flask-ask

Error: Exception information: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in >main status = self.run(options, args) File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 290, >in run requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, >bundle=self.bundle) File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1230, in >prepare_files req_to_install.run_egg_info() File "/usr/lib/python2.7/dist-packages/pip/req.py", line 326, in >run_egg_info command_desc='python setup.py egg_info') File "/usr/lib/python2.7/dist-packages/pip/util.py", line 716, in >call_subprocess % (command_desc, proc.returncode, cwd)) InstallationError: Command python setup.py egg_info failed with error code 1 >in /tmp/pip-build-IHwQ27/cryptography

我试图运行PIP运行PIP安装之前安装加密烧瓶问它让我的错误：

我也试过手动下载tar.gz文件形成的PyPI的网站，但这种具有相同错误结束。

如果有人能告诉我一个解决方案，我会很高兴吗？

你可以用'--verbose'运行你的'pip install'命令，这样我们就可以看到输出了吗？ – AK47

在运行'pip install flask-ask'之前尝试运行'pip install cryptography'， – AK47

在Pi上，升级pip3后我的运气好多了。尝试

sudo -H pip3 install --upgrade pip

然后再次尝试安装。
