com/sencha/core/functional/Action：不支持的major.minor 51.0版和java 1.8

Question

我不相信这是重复的，因为我无法在 stackoverflow 和其他网站/论坛上找到适用的解决方案。我在下面列出了我尝试过但没有奏效的所有内容。

我试图在 OSX El Capitain 的终端中运行命令“sencha app build native”，但遇到以下错误。

错误告诉我我的 java 设置有问题，但我不知道是什么问题。在终端中检查我的版本会显示以下内容。

$ java -版本 java版本“1.8.0_101” Java(TM) SE 运行时环境 (build 1.8.0_101-b13) Java HotSpot(TM) 64 位服务器 VM（内部版本 25.101-b13，混合模式）

通过系统首选项打开 java 仅显示安装了一个 Java 版本，即 1.8，安装路径位于 '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java'

在终端中运行 '/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version' 也会显示版本 1.8

运行 '/usr/bin/java -version' 也会给出 1.8 版

我已尝试添加这 3 行的变体以尝试解决问题，但它似乎并没有改变任何东西。如您所见，我还尝试更改内存以防万一它可能是内存问题

ANT_OPTS="-Xms1024m -Xmx2048m"
export PATH="/usr/local/bin:$PATH"
export JAVA_HOME="/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java"

我也尝试运行 'sencha app build -c'，但出现了同样的错误。

我还尝试将以下内容添加到 sencha.cfg 以查看是否有帮助

cmd.jvm.args=-Xms512m -Xmx2048m

我还尝试从苹果 https://support.apple.com/kb/dl1572 安装此更新，它说它安装的是 Java 6 运行时的旧版本

我也尝试安装 java sdk 7 和 java sdk 8 看看是否有帮助，没有运气

我还可以尝试做什么来修复与 Sencha 构建相关的错误“Unsupported major.minor version 51.0”

Answer 1

我终于通过将我的 JAVA_HOME 变量更改为“/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home”解决了这个问题

我将以下内容放在 .bashrc 和 .bash_profile 中，确保删除与 java 或 JAVA_HOME 变量相关的任何其他内容。您可以使用类似 'nano /Users/$USER/.bash_profile' 的命令来编辑文件

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home"
export PATH=$JAVA_HOME/bin:$PATH

在终端中键入“echo $JAVA_HOME”以确保设置正确的路径。

然后重新启动你的 mac 并尝试再次运行“sencha app build native”命令，它应该可以工作或抛出一个不同的错误（至少是它的进度）

请注意，在执行此操作之前您需要安装 jdk 1.7，请在此处下载 http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

您的版本可能与我的不同，因此打开终端并输入“cd /Library/Java/JavaVirtualMachines/”以切换目录，然后输入“ls -la”以列出您在那里拥有的所有文件。您应该会看到一个名为 jdk1.7.0_XX.jdk 的文件
