我正在尝试在我的项目中添加社交身份验证，但是当我尝试安装时Django-allauth https://django-allauth.readthedocs.io/en/latest/installation.html它给了我错误我已经尝试过这个post https://stackoverflow.com/questions/22073516/failed-to-install-python-cryptography-package-with-pip-and-setup-py但运气不好，它给了我另一个与以下相关的错误安装工具_rust https://pypi.org/project/setuptools-rust/我给出了我尝试过的命令以及与每个命令相关的错误。

$ pip3 install django-allauth

Error :

/tmp/pip-build-7e3fgl32/密码学/ 然后我尝试安装安装工具_rust因为它会导致错误

$ pip3 install setuptools_rust

这个包没有给我任何安装成功的错误 然后我尝试从中安装一些命令post https://stackoverflow.com/questions/22073516/failed-to-install-python-cryptography-package-with-pip-and-setup-py

$ sudo apt-get install build-essential libssl-dev libffi-dev python-dev

它没有改变任何检查命令的响应

它似乎pip3 install --upgrade pip对我不起作用然后我尝试了这种方法并且它起作用了

python3 -m pip install --upgrade pip

多亏了这个post https://askubuntu.com/a/1032408/1163906
