我解决了，生产.rb文件出了问题
答案 0 :(得分：0)
根据您的日志，您的捆绑包已完成。向下滚动，您会注意到它抱怨语法错误
SyntaxError: /tmp/build_fa26cd38a82ac06672bf2f99e38da7bf/config/environments/production.rb:86: syntax error, unexpected end-of-input, expecting keyword_end
检查文件和行号
答案 1 :(得分：0)
所以它抱怨heroku上安装的bundler版本比你在dev机器上创建Gemfile.lock时使用的版本旧。
查看log heroku正在使用bundler 1.11.2，检查您正在使用的Bundler版本。如果它不同，那么试试你的开发机器：
.table-cell:filled {
-fx-background-color: -fx-my-cell-background;
}
.table-view:row-selection .table-row-cell:selected .table-cell {
-fx-background-color: null;
}
.table-view:cell-selection .table-cell:selected {
-fx-background-color: -fx-table-cell-border-color, -fx-background;
}
然后您需要执行以下任一操作：
1）重新生成你的Gemfile.lock，使它说它与1.11.2捆绑在一起。（推荐但可能很痛苦）
OR
2）手动编辑Gemfile.lock中的Bundler版本。
完成后，现在将更新的gemfile.lock文件推送到git branch。
