Q2studio npm start error

[andrewsanchez]

Hi, @hesterlee and welcome to the forum!

The error message states:

@hesterlee

npm ERR! Make sure you have the latest version of node.js and npm installed.

It also lists the version of node you are using:

@hesterlee

npm ERR! node v6.11.2

When you follow the installation instructions here, you should get a newer version of node. If you followed those instructions (especially conda install gevent nodejs -c defaults --override-channels, which installs nodejs into your qiime 2 environment if it is activated) and you are still having a problem, then that means your computer is using a different node installation. If you activate your qiime 2 environment and then use these commands: which node and which npm, what do you see?

Your issue may be similar to the one here:

mafft does not work inside my Qiime2 environment

When it comes to the PATH variable, the order of items matters. You can see below that the mafft installation external to your qiime 2 conda environment appears before the qiime 2 environment. It’s important that the qiime 2 environment comes first. Otherwise, your computer will favor programs that appear earlier in the list. PATH=/opt/local/bin/mafft:/Users/m213406/Filtlong/bin:/Users/m213406/nanotimeparse:/Users/m213406/NanoOK/bin:/opt/local/share/arb/bin:/opt/local/bin:/opt/local/sbin:/Use…

I would suggest simply creating a fresh qiime 2 enviroment and follow the q2studio installation instructions closely to see if that resolves the issue. Let me know how it works out!
