尝试过：

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

也尝试过：

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

Answer 1

我在尝试的时候遇到了类似的问题

pip install --user --upgrade bcrypt

我安装了 debian python-cffi 软件包，版本 0.8.6。删除它后，上面的命令成功了。即使使用 pip 安装了新版本 cffi，旧版本也会以某种方式引起问题。

还有

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

似乎即使安装了 python-cffi 软件包也能正常工作。

Answer 2

ensure that the required dependencies are installed 来自 bcrypt
