嘗試：

sudo apt-get remove build-essential libffi-dev python-dev 
sudo apt-get install build-essential libffi-dev python-dev 

也試過：

sudo apt-get remove python-pycparser 
sudo apt-get install python-pycparser 

Answer 1

我試圖

pip install --user --upgrade bcrypt 

，當我不得不安裝的Debian中的python-CFFI包，版本0.8.6遇到類似的問題。刪除它後，上面的命令成功。即使使用pip安裝了新版本的cffi，舊版本也會出現問題。

而且

pip uninstall bcrypt cffi pycparser 
pip install --user --upgrade cffi 
pip install --user --upgrade bcrypt 

似乎已安裝的python-CFFI包，即使工作。
