Jupyter Scala Kernel Missing

我在OS X 10.10.5上运行.我正在尝试将 Scala内核添加到我的Jupyter笔记本中.

$jupyter --version
4.0.4

$conda --version
conda 3.17.0

我从git下载了jupyter-scala,然后从源代码构建了Scala 2.11.

$sbt cli/target

$ls -l /Users/davidlaxer/jupyter-scala/cli/target/scala-2.11/

total 224

drwxr-xr-x 4 davidlaxer staff 136 Sep 21 12:39 classes
-rw-r--r-- 1 davidlaxer staff 114465 Sep 21 12:39 jupyter-scala-cli_2.11.6-0.2.0-SNAPSHOT.jar

$sudo jupyter kernelspec install scala-2.11/

Password:

[InstallKernelSpec] Installed kernelspec in /usr/local/share/jupyter/kernels/

David-Laxers-MacBook-Pro:target davidlaxer$jupyter kernelspec list

Available kernels:

ir
julia-0.3
matlab_kernel
python2

$ls -l /usr/local/share/jupyter/kernels/
total 224
drwxr-xr-x  4 root  wheel     136 Sep 21 12:39 classes
-rw-r--r--  1 root  wheel  114465 Sep 21 12:39 jupyter-scala-cli_2.11.6-0.2.0-SNAPSHOT.jar

为什么我没有看到scala2.11内核？

没有斯卡拉！

解决方法

要从源代码安装jupyter-scala,你应该做类似的事情

git clone https://github.com/alexarchambault/jupyter-scala.git
cd jupyter-scala
sbt cli/pack
cli/target/pack/bin/jupyter-scala

然后ipython kernelspec列表应该显示scala211.

对于Scala 2.10内核,请查看scala-2.10.x分支,并执行sbt 2.10.5 cli / pack而不是sbt cli / pack.内核名称是scala210.请注意,要以这种方式同时拥有两个内核,您应该例如克隆两个不同目录中的仓库.
