ubuntu16.04安裝angr 升級python3.7

由於angr的某些庫需要python版本>=3.6，索性升級到了python3.7

升級python到3.7

sudo add-apt-repository ppa:deadsnakes/ppa
# 添加自定義源
sudo apt-get update
# 更新軟件包
sudo apt-get install python3.7
# 安裝python3.7
sudo apt-get -y install python3.7 python3.7-dev python3-pip
# 安裝python3.7-dev啥玩意和pip
python3.7 -m pip install pip --upgrade
pip install --upgrade pip
# 升級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
# 設置python的時候出來python3.7

# 設置python3時候出來python3.7
1. 打開.bashrc
 	vim ~/.bashrc
2. 在.bashrc中添加
 	alias python3=python3.7
 	or
 	alias python3='/usr/bin/python3.7'
3. 保存並退出文件編輯，使配置生效
 	source ~/.bashrc

# 更改軟鏈接，設置默認喚起python3版本
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python3 /usr/bin/python

安裝angr

1. 安裝依賴

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

2. 安裝angr

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

• 若報錯：“未找到命令”

  進行virtualenvwrapper初始化

  輸入

  export WORKON_HOME=$HOME/Python-workhome
  

  source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
  

• 若報錯：ERROR: pyvex 7.8.9.26 has requi rement future=-0.16.0, but you’ll have future 0.18.2 which is incompatible.
  將python2和python3的future均改爲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

# 解決
sudo apt-get install python3-pip
sudo pip3 install virtualenv virtualenvwrapper
source .bashrc

mkvirtualenv --python=$(which python3) angr

# 離線安裝pip包cle-8.20.1.7
# (如果install angr可以安裝，則無需手動安裝)

pip install angr
