我试图安装一些软件包，并开始得到一个错误。然后在ubuntu中使用多个命令来更新一些东西，但错误是相似的

pip install -U pip setuptools
or
python3 -m pip install --upgrade pip
or
sudo -H pip3 install --upgrade pip

以下是错误示例

user@machine:~$ pip install cryptography

我已经按照这里的建议使用apt-get install libffi-dev python-dev python3-dev和apt-get install build-基本libssl-dev更新了系统
