python - pip installrequirements.txt 无法正常工作

Question

我正在尝试在我的 Digital Ocean Django 服务器上安装所有 Python/Django 包。我的 requirements.txt 位于根目录中，因此我执行 pip install -rrequirements.txt - 但它不起作用。这是我的 requirements.txt:

这是日志:

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-9eo5rb8l/get/

我认为它正在工作，只有 get==0.0.0 包出现错误 - 但是当我执行 pip freeze 时，它显示:

Django==1.11.8
django-trumbowyg==1.0.3
gunicorn==19.7.1
psycopg2==2.7.3.2
pytz==2017.3

这表明它们都不起作用。我使用 pip install django-trumbowyg 手动安装了 django-trumbowyg 这就是为什么它在那里，但其他的只有在设置 Django 服务器时才在那里。那么为什么 pip install -rrequirements.txt 不起作用以及如何修复它？

Answer 1

1. 您应该修复 requirements.txt 中的软件包版本。
2. 从日志中，它显示 pip 正在使用来自某处的模块的缓存版本，您可能应该尝试 --no-cache-dir 选项。
