无法初始化编译器:在编译器镜像中找不到对象java.lang.Object [英] Failed to initialize compiler: object java.lang.Object in compiler mirror not found

问题描述

在Ubuntu 16.04上，我安装了scala:

On Ubuntu 16.04, I installed scala:

$ls ~/Binary/scala-2.11.8
bin  doc  lib  man
$grep -A 2 SCALA ~/.bashrc
SCALA=~/Binary/scala-2.11.8
SBT=~/Binary/sbt
export PATH=$PATH:$SCALA/bin:$SBT/bin

在安装openjdk8的情况下，打开REPL时scala失败:

With openjdk8 installed, scala fails when opening the REPL:

$javac -version
javac 1.8.0_91
$ 
$scala
Welcome to Scala 2.11.8 (OpenJDK 64-Bit Server VM, Java 9-internal).
Type in expressions for evaluation. Or try :help.

** Note that as of 2.8 scala does not assume use of the java classpath.
** For the old behavior pass -usejavacp to scala, or if using a Settings

我该如何解决?

推荐答案

使用Java 8版本的OpenJDK为我解决了此问题.

Using the Java 8 version of OpenJDK resolved this issue for me.

sudo update-alternatives --config java
sudo update-alternatives --config javac
