ubuntu16.04安装angr 升级python3.7

由于angr的某些库需要python版本>=3.6，索性升级到了python3.7

升级python到3.7

sudo add-apt-repository ppa:deadsnakes/ppa
# 添加自定义源
sudo apt-get update
# 更新软件包
sudo apt-get install python3.7
# 安装python3.7
sudo apt-get -y install python3.7 python3.7-dev python3-pip
# 安装python3.7-dev啥玩意和pip
python3.7 -m pip install pip --upgrade
pip install --upgrade pip
# 升级pip
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7 2
# 设置python的时候出来python3.7

# 设置python3时候出来python3.7
1. 打开.bashrc
 	vim ~/.bashrc
2. 在.bashrc中添加
 	alias python3=python3.7
 	or
 	alias python3='/usr/bin/python3.7'
3. 保存并退出文件编辑，使配置生效
 	source ~/.bashrc

# 更改软链接，设置默认唤起python3版本
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python3 /usr/bin/python

安装angr

1. 安装依赖

   sudo apt-get install python-dev libffi-dev build-essential virtualenvwrapper
   export WORKON_HOME=$HOME/Python-workhome
   source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
   

2. 安装angr

mkvirtualenv angr && pip install angr
(或)
mkvirtualenv --python=$(which python3) angr && pip install angr

• 若报错：“未找到命令”

  进行virtualenvwrapper初始化

  输入

  export WORKON_HOME=$HOME/Python-workhome
  

  source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
  

• 若报错：ERROR: pyvex 7.8.9.26 has requi rement future=-0.16.0, but you’ll have future 0.18.2 which is incompatible.
  将python2和python3的future均改为0.16.0版本
  命令：

  sudo pip uninstall future
  sudo pip install future==0.16.0
  sudo pip3 uninstall future
  sudo pip3 install future==0.16.0

pip install angr
