我安装了一些较旧版本的 grails (3.3.8)，并尝试使用 sdkman 安装较新版本 (4.0.4)。安装成功了，但 grails 现在完全崩溃了。我还从 oracle 网站的 dmg 将 java 更新为 14。基本上 grails 现在完全崩溃了。任何想法如何解决？

我没有看到卸载 java 14 或及时返回的简单方法。

echo $PATH
/Users/xx/.sdkman/candidates/groovy/current/bin:/Users/xx/.sdkman/candidates/grails/current/bin:/Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Appz/apache-jmeter-5.3/bin:/usr/local/go/bin:/usr/local/share/dotnet:/opt/X11/bin:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Users/xx/go/bin:/Users/xx/dev/grails-3.3.8/bin:/Users/xx/dev/flutter/bin:/Users/xx/dev/gradle-5.1.1/bin:/appz/cassandra/bin

我猜我可以尝试破解路径等来修复。

这是我当前的 .bash_profile：

vi .bash_profile

export JAVA_HOME=`/usr/libexec/java_home`
export GRAILS_HOME=/Users/xx/dev/grails-3.3.8

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
export PATH=$PATH:$GRAILS_HOME/bin

# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
export GRADLE_HOME=/Users/xx/dev/gradle-5.1.1
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
PATH="${PATH}:/Users/xx/dev/flutter/bin"
PATH=$PATH:$GRADLE_HOME/bin


# Cassandra
if [ -d "/appz/cassandra" ]; then
    export PATH="$PATH:/appz/cassandra/bin"
fi

export PATH

#THIS MUST BE AT THE END OF THE FILE FOR SDKMAN TO WORK!!!
export SDKMAN_DIR="/Users/simonh/.sdkman"
[[ -s "/Users/xx/.sdkman/xx/sdkman-init.sh" ]] && source "/Users/xx/.sdkman/bin/sdkman-init.sh"

这很奇怪，为什么当 sdkman 安装并使 4.0.4 成为当前版本时，grails home 仍然是 3.3.8？为什么不编辑路径？我应该将 gradle 设置为哪个版本？我如何回到 java 8，因为我认为 java 14 中存在导致 grails 问题的错误？

好的，想通了。

首先，我必须手动修复 java 版本。

为此，请访问

 $ /usr/libexec
 $ ./java_home -V

这会输出一个或多个版本：

14.0.2, x86_64: "Java SE 14.0.2"    /Library/Java/JavaVirtualMachines/jdk-14.0.2.jdk/Contents/Home
1.8.0_131, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

现在编辑我们的 .bash_profile 并将 JAVA_HOME 行替换为您想要的版本，无论是整个版本（1.8.0_131）还是主要版本（1.8）：

 export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

现在，当您打开一个新窗口并执行“java -version”时，您会得到 1.8，而当您执行“grails -version”时，我最终会得到 4.0.4。

耶！

奇怪的是，仅更改 JAVA_HOME 不应该影响路径上的内容，但似乎。即仅设置 JAVA_HOME 不应该影响我输入“java”时运行的 java 版本，但它确实如此。即 muy bash_profile 中没有诸如“PATH=$PATH:$JAVA_HOME/bin”之类的行。
