    ----------------------------------------
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，并且get==0.0.0包只有一个错误 - 但是当我执行pip freeze它显示：

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

这表明他们都没有工作。 我使用pip install django-trumbowyg django-trumbowyg手动pip install django-trumbowyg ，这就是为什么它在那里，但其他人只在那里设置了 Django 服务器。 那么为什么pip install -r requirements.txt不起作用，我该如何解决呢？

Answer 1

1. 您应该修复requirements.txt的包版本。
2. 从日志中，它显示 pip 正在使用某个地方的模块的缓存版本，您可能应该尝试--no-cache-dir选项。

Answer 2

您正在尝试安装get 的0.0.0版

您应该在requirements.txt 中指定正确的版本号。

Answer 3

有时图书馆可能会出现问题。

只需编辑requirements.txt. 并删除您遇到问题的任何软件包中的版本号。

django-widget-tweaks==1.4.1
get
imageio==2.1.2
