Linux的Windows子系统无法识别JAVA_HOME环境变量 [英] Windows Subsystem for Linux not recognizing JAVA_HOME Environmental Variable

问题描述

我试图让WSL识别我的Windows安装的JAVA_HOME环境变量.我附上了bashrc中的内容以及Windows环境变量中的内容以及cmd和bash的输出.

I'm trying to get WSL to recognize my windows installed environmental variable of JAVA_HOME. I attached of what I have in my bashrc and what I have in my windows environmental variables along with outputs from cmd and bash.

bashrc的结尾是什么:

What's at the end of my bashrc:

export JAVA_HOME="/mnt/d/Program Files/Java/jdk-11.0.1"
export PATH="/mnt/d/Program Files/Java/jdk-11.0.1/bin:$PATH"

CMD输入/输出:

C:\Users\jaall>javac --version
javac 11.0.1

BASH输入/输出:

BASH INPUT/OUTPUT:

myubuntu_name@DESKTOP-LUK3BII:~$ javac --version

Command 'javac' not found, but can be installed with:

sudo apt install default-jdk
sudo apt install openjdk-11-jdk-headless
sudo apt install ecj
sudo apt install openjdk-8-jdk-headless

我已经坚持了一段时间，无法解决问题或无法在线找到可行的解决方案.谢谢！

I've been stuck on this for awhile and can't figure it out or find a working solution online. Thanks!

推荐答案

根据Biswapriyo的建议，您应该使用WSLENV.

As Biswapriyo suggested, you should use WSLENV.

1. 打开PowerShell.然后将JAVA_HOME设置为您的Java安装路径.

1. Open PowerShell. Then set JAVA_HOME to the path to your java installation.

在您的情况下，运行setx JAVA_HOME "D:\Program Files\Java\jdk-11.0.1"

您应该看到一条消息，内容为:成功:指定的值已保存.

You should see a message that says "SUCCESS: Specified value was saved.

1. 然后运行setx WSLENV "JAVA_HOME/p"

您应该再次看到成功消息.

You should see the success message again.

1. 在您的WSL bash提示符中键入"env".

此时您应该看到正确设置了JAVA_HOME.

You should see JAVA_HOME correctly set at this point.

注意:如果第2步不起作用，则可能要更改JAVA_HOME的路径以包含"\ bin"文件夹.

Note: If step 2 doesn't work, you might want to changing the path to JAVA_HOME to include the '\bin' folder.
