所以我玩2.0.4项目，我试图推送到heroku。该项目使用play authenticate插件，一切都按预期在本地工作，所以我试图将它推送到heroku。
我花了好几个小时试图让它现在起作用，但运气不佳。
所以我修改了我的application.conf：
#db.default.driver=org.h2.Driver
db.default.url="the url for my postgres database"
# db.default.user=sa
# db.default.password=
修改了我的Procfile：
web: target/start -Dhttp.port=${PORT} -Dplay.version=2.0.4 -DapplyEvolutions.default=true -Ddb.default.driver=org.postgresql.Driver -Ddb.default.url=$DATABASE_URL ${JAVA_OPTS}
我的应用依赖项中包含postgresl：
val appDependencies = Seq(
"be.objectify" %% "deadbolt-2" % "1.1.3-SNAPSHOT",
"com.feth" %% "play-authenticate" % "0.2.2-SNAPSHOT",
"postgresql" % "postgresql" % "9.1-901.jdbc4"
)
我在conf / evolutions / 1.sql中有数据库演变：

我执行以下命令并尝试推送到heroku（在我的repo目录中）：
git init
git add .
git commit -m "init"
git push heroku master
尝试加载应用程序时，日志看起来像这样：

我觉得我已经尝试了一切，包括重置heroku数据库。我已经尝试在没有默认进化的情况下推送应用程序，但我仍然得到相同的错误。我不确定它是否与play-authenticate模块有关，因为错误会提示但我怀疑它因为它在本地使用H2数据库而没有错误。
