nextflow initial installation

[chenyanniii]

Hello,

I used conda install nextflowto install nextflow, and not able to run nextflow. Could you help find the solution. Thank you!

When I run nextflow run hello

Java HotSpot(TM) 64-Bit Server VM warning: Option --illegal-access is deprecated and will be removed in a future release.
Error: Could not find or load main class nextflow.cli.Launcher
Caused by: java.lang.ClassNotFoundException: nextflow.cli.Launcher

Hi @chenyanniii ,

It's quite strange that your JAVA_HOME is not indicating the java version installed via conda located at /usr/local/anaconda3/bin/java

Please update the JAVA_HOME in your .zshrc and try again.
