FileNotFoundError：将启动推送到heroku后[Errno 2]

Question

我正在尝试部署最新的scrapinghub / splash

我在win10上使用git-bash。我将回购分叉到https://github.com/kc1/splash/blob/master

并且我一直在尝试遵循Using docker, scrapy splash on Heroku来修改docker文件

在使用Linux行结尾克隆仓库后，使用以下命令：

git clone --config core.eol=lf <repository>

我能够使用heroku命令行推送整个仓库 与：

$ heroku container:push web --app MYAPP

这样做之后：

$ heroku container:release web --app MYAPP

我得到了屏幕截图。日志显示：

我该如何解决？

Answer 1

我还没有测试过如何自己部署它，但是当我阅读Docker文件时，我看到了导致您错误的可能原因。

在Dockerfile中，Volume映射器具有注释掉的代码行，该代码行将虚拟环境映射到包含splash/filters的物理文件空间。我不知道为什么图像的作者会这样做，但是它与您的错误代码一致。

因此，在Dockerfile中，将卷映射器取消注释到splash / filter目录

VOLUME [ \
    "/etc/splash/proxy-profiles", \
    "/etc/splash/js-profiles", \
    "/etc/splash/filters", \ ##UNCOMMENTED LINE
    "/etc/splash/lua_modules" \
]
