Compilation 在chicaogboss中编译bson时出现语法错误

我们升级了chicagoboss，它依赖于“bson”。当我们使用

/rebar update deps compile

编译chicagoboss时。编译chicagoboss时会抛出语法错误。 但基本上我们是从“头”上取的。我不确定这是不是个好主意

Pulling bson from {git,"git://github.com/mongodb/bson-erlang","HEAD"}
Cloning into 'bson'...

以下是编译错误：

有人能提出解决方案吗？

问题的根源是来自BossDB的

mongodb erlang

ce9bf77902

（当前的ChickegoBoss）使用了

HEAD

版本的

bson

，该版本现在与erlang/OTP<17不兼容

---

在

boss\u db

依赖项之前，可以在rebar.config中指定

bson

的工作版本。正如我所看到的，标签

v0.2

对于

R16B03-1

是可以的

看起来您正试图在使用旧erlang的机器上编译带有映射的新bson。你有哪个版本？@P_A-好的，我使用的是

Erlang R16B01（erts-5.10.2）

。但是现在我们不能升级它。获取旧版本的

erlang bson

的方法是什么？您可以在

rebar.config

中的

bson

依赖项之前指定

bson的工作版本。正如我所看到的，tag
v0.2
是可以的。@P_A-是的，谢谢你的努力。我从一个旧的提交中提取了它。像这样：{git，“git://github.com/mongodb/bson-erlang“，“旧提交哈希”}`。你可以评论你的建议作为回答。我会接受的。@Vetal4eg-是的，请看一下上面的评论`{git，”git://github.com/mongodb/bson-erlang“，“旧提交哈希”}
