python - 构建 python 时裤子因 scala 相关错误而失败

Question

我正在尝试使用裤子构建一个简单的 pex 来测试它。但是，我遇到了一些问题:

$ ./pants binary src/python/hworld
INFO] Detected git repository at /home/jovalko/pants on branch master

23:03:48 00:00 [main]
               (To run a reporting server: ./pants server)

               FAILURE

由于很难将我的所有问题都表达为一个粘贴，我已经发布了它们 on github (为外部链接道歉)。

相关位是我的顶级 BUILD:

# Pants source code
source_root('src/python')

和我的 hworld 二进制文件的 BUILD:

python_binary(name='hworld',
    source='hworld.py'
)

也许还有 BUILD.tools 但它很长，我直接从 pantsbuild/pants 复制了它(正如文档中所建议的那样，我从另一个 repo 的工作版本开始)。

我尝试了各种排列(使用 BUILD.tools，没有 pants.ini 中的各种东西)但在每种情况下它都失败了，因为与 scala 相关的东西......这有点令人困惑，因为我只构建 python。而且，在 pantsbuild/pants 存储库中运行对我来说效果很好。

我会提醒您，我是裤子的新手，很可能我做了一些愚蠢的事情；)。有什么想法吗？

为了防止其他人碰到这个问题，我通过从我的 BUILD.tools 中删除与 scala 相关的(特别是任何使用 scala_jar 的东西)条目来解决它:
