Question

我尝试构建最新的（dev）版本的Julia（v0.7），并希望从Jupyter Notebook中使用这个内核。当我试着跑步时 Pkg.add("IJulia")并构建模块，构建失败。我得到的错误是

将此作为问题发布在github上是否合理，或者问题仅适用于稳定版本v0.6？

在即将发布的Julia v0.7中，变量JULIA_HOME（来自Base模块）已重命名为Sys.BINDIR [1]。

在查看存储库之后，似乎他们目前正在将IJulia移植到0.7版本。我认为现在提供解决方案如何解决这一特定问题，我认为提交问题会很痛苦。此特定错误消息也未在持续集成构建中显示[2]。但是，鉴于很长的更改列表[1]并且版本0.7尚未发布，可能还有许多其他问题。因此，不要指望IJulia在这次改变后与Julia v0.7（dev）合作。
