Question

我从Oracle网站（jre-8u25-macosx-x64.dmg）下载了JRE8。然后我打开dmg并运行安装。安装进度已开始，但随后发生以下错误：

The installation failed.

The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.

如果我尝试安装JRE7，则会出现同样的错误。

我还尝试下载jre-7u71-macosx-x64.tar.gz并解压缩，但之后Java拒绝正常工作。 java -version很好，但以下代码会打印Unknown：

System.out.println(System.getProperty("os.name"));

这很奇怪。有没有人遇到同样的问题？

我运行sudo diskutil repairPermissions /

然后我再次运行安装程序并按下⌘ + L。日志是：

看起来您需要更新Apple版本的Java，或者安装程序在以某种方式下载后会出现问题。通常可以通过运行更新工具并从终端重新下载JRE包来解决此问题：

打开终端并运行以下命令：

softwareupdate -ir

如果需要，请检查/更新Apple的Java版本。

cd ~/desktop
curl -v -j -k -L -H "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u25-b17/jre-8u25-macosx-x64.dmg > jre-8u25-macosx-x64.dmg

将JRE磁盘映像下载到桌面。

mkdir ~/desktop/jre
hdiutil attach -mountpoint ~/desktop/jre jre-8u25-macosx-x64.dmg

安装磁盘映像。

sudo installer -pkg ~/desktop/jre/Java\ 8\ Update\ 25.pkg -target /

安装JRE包。

hdiutil detach ~/desktop/jre

卸载磁盘。

java -version

检查Java版本。

java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

无法在OS X Yosemite上安装JRE8 / JRE7
