无法在本地计算机上安装requirements.txt并运行项目

Question

Django版本是1.7.1 python版本是3.9.2

嗨，Python/Django开发人员！我真的需要你的帮助，因为我在这些类型的错误中困了一周。我现在面临的问题是，当我尝试通过键入以下命令来安装需求时

pip install -r main_requirements.txt

它安装了大多数需求，但没有安装这些包：

configobj
matplotlib
psycopg2
pysqlite
pyOpenSSL

unittest2
xgboost

当涉及到"configobj"时，它会给出Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.错误，它也会在安装matplotlib错误时给出错误：

Answer 1

看起来你的包在安装时依赖于其他包。Pip对您的需求进行了两次遍历:首先它下载所有包并运行每个包的setup.py以获取其元数据，然后在第二次遍历中安装所有包。

这也是为什么当你一个接一个地安装软件包时看不到这个错误的原因:如果你一次安装一个，在你pip安装“你的软件包”之前，你将在你的环境中完全安装。

唯一解决方案是在运行pip install -r requirements.txt之前安装pip install "“--您不能用一个requirements.txt文件在一个命令中完成这项工作。
