python pip麻烦从requirements.txt安装 [英] python pip trouble installing from requirements.txt

问题描述

过去，我对点子很幸运，但是在Venv上安装一些东西的工作让我有些头疼. 我不断收到类似的错误 在某个软件包中根本找不到任何分发包在/root/.pip/pip.log

I've had great luck with pip in the past, but working at installing some stuff in a venv on is giving me some headaches. I keep getting errors like No distributions at all found for somepackage Storing debug log for failure in /root/.pip/pip.log

Could not find any downloads that satisfy the requirement somepackage

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-RjqjFW/psycopg2

我知道这些软件包已安装在主系统上，但就像它们在venv上不起作用一样.大家如何解决这个问题?这已经是漫长的一天，我只是不了解问题是什么，特别是因为它们在我的本地系统上工作，它们在我的远程系统上的主python安装上工作，但出于某种疯狂的原因却不在venv中工作.有什么想法吗?

I know these packages are installed on the main system, but its like they won't work on the venv. How do you all get around this problem? It's been a long day and I just don't understand what the problem is, especially because they work on my local system, they work on the main python install on my remote system, but not in the venv for some crazy reason. Any ideas?

这里是需求，我认为这对django来说有点困难，但这就是pip Frozen> requirements.txt给我的

推荐答案

我看到了一些问题:

1. 您的requirements.txt用于基本系统Python，而不适用于任何虚拟环境. Django没有任何外部依赖关系.

1. Your requirements.txt is for the base system Python, not any virtual environment. Django does not have any external dependencies.

您正在使用root用户在虚拟环境中安装软件包(或者在不应该使用sudo的情况下使用).

You are using the root user to install packages in your virtual environment (or you are using sudo when you shouldn't).

最好的选择是从头开始:

The best option is to start from scratch:

$ virtualenv myvenv
...
$ source myvenv/bin/activate
(myvenv) $ pip install django
...
(myvenv) $ pip freeze > requirements.txt
