Question

我正在尝试将一个python项目推送到Heroku，并且每次运行git push heroku master时都会出现此错误

$ git push heroku master

我也曾尝试在笔记本电脑上查找丢失的文件，但我无法，请问如何解决此问题？

这是我的required.txt文件

Answer 1

我是初学者，所以请带一点盐。

我删除了需求文件中的所有“ @路径”后缀，只留下了软件包名称，这阻止了此错误的发生。

所以：

astroid 
certifi==2020.6.20
click==7.1.2
colorama==0.4.3
Flask==1.1.2
Flask-SQLAlchemy==2.4.3
gunicorn==20.0.4
isort==4.3.21
itsdangerous==1.1.0
Jinja2==2.11.2
lazy-object-proxy==1.4.3
MarkupSafe==1.1.1
mccabe==0.6.1
pylint 
six==1.15.0
SQLAlchemy==1.3.18
toml 
typed-ast==1.4.1
Werkzeug==1.0.1
wincertstore==0.2
wrapt==1.11.2

Answer 2

嗨，我刚遇到这个问题并能够解决。以防将来任何人遇到相同问题时发帖。

按照@extracheez的说明删除多余的@路径。然后确保您提交并在之后推送到Git。那为我解决了。

git add -A
git commit -m "removed surplus @ paths in requirements.txt file"
git push -u origin master

不过可能会弹出另一个错误，例如FileNotFoundError: [Errno 2] No such file or directory: '/tmp/build_51de3815/static'。

要解决此问题，请在您的静态文件夹中创建一个.temporary_file文件。与Git无法跟踪空目录有关，因此，它在Heroku中不存在。

touch static/.keep

错误：由于环境错误而无法安装软件包：[Errno 2]没有这样的文件或目录：'/ C：/ ci / astroid_1592481955828 / work'
