一个 Python 3.6 Django ==11 应用程序正在部署，并且代码会定期推送到昨天。现在我有错误:

另一个问题——如上所示，我知道的是默认构建 DIR 中不存在 OpenCv [cv2]。我正在为此部署 Python OpenCV buildpack - 但需要先解决此问题:
File "/tmp/build_989d7449dd0cd18694a87448cb09f19f/indexapp/image_processing.py", line 7, in <module>
remote: import cv2
remote: ModuleNotFoundError: No module named 'cv2'
最佳答案
我刚刚遇到了同样的错误:
AttributeError: module 'pip._vendor.requests' has no attribute 'Session'
清除 Heroku 构建缓存为我解决了这个问题。这是您需要执行的操作:
安装官方heroku-repo plugin for the Heroku CLI :
$ heroku plugins:install heroku-repo
清除应用的构建缓存:
$ heroku repo:purge_cache -a APPNAME
触发部署以重建您的应用
清除构建缓存会导致 pip 在下一次构建时从头开始重新安装 Python 依赖项，而不是尝试升级当前的依赖项集。
这为我解决了 AttributeError，希望对您有所帮助!

我正在尝试设置一个puppet节点，但rubygems似乎不正常。如果我通过它自己的二进制文件(/usr/lib/ruby/gems/1.8/gems/facter-1.5.8/bin/facter)在cli上运行facter，它工作正常，但如果我通过由rubygems(/usr/bin/facter)安装的二进制文件，它抛出:/usr/lib/ruby/1.8/facter/uptime.rb:11:undefinedmethod`get_uptime'forFacter::Util::Uptime:Module(NoMethodError)from/usr/lib/ruby

在选择我想要运行操作的频率时，唯一的选项是“每天”、“每小时”和“每10分钟”。谢谢!我想为我的Rails3.1应用程序运行调度程序。 最佳答案 这不是一个优雅的解决方案，但您可以安排它每天运行，并在实际开始工作之前检查日期是否为当月的第一天。 关于ruby-如何每月在Heroku运行一次Scheduler插件？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/8692687/
