Nextflow 安装找不到 Java

Question

我目前正在尝试在我的计算机上安装 nextflow，但我遇到了无法解决的 Java 错误消息。

curl -s https://get.nextflow.io | bash

ERROR: Cannot find Java or it's a wrong version -- please make sure that Java 8 or later is installed
NOTE: Nextflow is trying to use the Java VM defined by the following environment variables:
 JAVA_CMD: /Library/Java/JavaVirtualMachines/jdk-16.0.2.jdk/Contents/Home/bin/java
 JAVA_HOME:

在其他帖子上寻找解决方案，我尝试使用

export JAVA_HOME="$(/usr/libexec/java_home -v 1.7+)"

但现在我仍然有几乎相同的错误

ERROR: Cannot find Java or it's a wrong version -- please make sure that Java 8 or later is installed
NOTE: Nextflow is trying to use the Java VM defined by the following environment variables:
 JAVA_CMD: /Library/Java/JavaVirtualMachines/jdk-16.0.2.jdk/Contents/Home/bin/java
 JAVA_HOME: /Library/Java/JavaVirtualMachines/jdk-16.0.2.jdk/Contents/Home

我的 java 版本：

 java -version
 java version "16.0.2" 2021-07-20
 Java(TM) SE Runtime Environment (build 16.0.2+7-67)
 Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing)

如果你能给我一些克服这个问题的技巧，我将不胜感激。

Answer 1

看看你的脚本运行:

...
if [ $major -eq 0 ] && [ $minor -lt 26 ]; then
    version_check="^(1.7|1.8)"
    version_message="Java 7 or 8"
  else
    version_check="^(1.8|9|10|11|12|13|14|15)"
    version_message="Java 8 or later"
  fi
...

看起来需要 Java15 或更早版本。您可能只需添加 16 就可以了。
