在从新编译RYU时候碰到的问题。

1，import setuptools ImportError: No module named setuptools

解决

2，distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('pbr')

解决： wget  https://bootstrap.pypa.io/get-pip.py

          python get-pip.py

          pip install pbr

3 又会这样

在response时，没法返回，报错Can’t connect to HTTPS URL because the SSL module is not available

解决办法:

sudo apt-get install libssl-dev
sudo apt-get install openssl
进入到安装的python的目录下
./configure --enable-shared --enable-loadable-sqlite-extensions

sudo make
sudo make install

 

4. You are using pip version 8.1.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

更新下pip

解决：pip文件在usr/bin目录下，cd进去，进行如下修改

把下面的三行

from pip import main
if __name__ == '__main__':
    sys.exit(main())
换成下面的三行

from pip import __main__
if __name__ == '__main__':

5  ryu启动没有tinpc的问题
