Heroku 部署 - 未在 requirements.txt 上找到 javabridge 包的 java_home

Question

我正在运行 git push heroku master 将我的第一个应用程序部署到 heroku。我遇到了与依赖项有关的各种错误，因此在遵循此处的建议后： Heroku Upload - Could not find a version that satisfies the requirement anaconda-client==1.4.0 我从 requiremets.txt 文件中删除了所有“有问题的”包。其中一个包是 python-javabridge。

然而，一旦到达终点，它仍在尝试安装 python-javabridge，出现以下错误：

在开始之前，我使用 conda update --all 更新了所有软件包。我正在使用 Windows 10 64 位。蟒蛇。蟒蛇 3.7。 Spyder 4.2.0 IDE。用于命令的 Spyder 终端。如何从我的 Windows 机器上修复这个 Linux 环境变量问题，或者如何让它根本不安装 javabridge？ 提前致谢！

Answer 1

我遇到了类似的问题，但使用了不同的库（pyspark 和更多 2 个 ipython-something）。

我找到的更简单的解决方案是从 requirements.txt 中删除这个库；

应用程序是否依赖于这个库？您是否尝试删除此库？

有时，安装它只是因为您使用 conda 安装了一些库。
