I have been using a tool to carryout pan-genome analysis with PanX and tried to visualise the results graphically by using PanX-visualization. I have followed all the instruction specified in the panX-visualization manual. Since, It needs npm, I tried to install npm but end up with the following error,
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@2.1.3 (node_modules/fsevents):

To fix this error, I upgraded my default nodejs and nvm into nodejs v14.8.0 and nvm v14.4.0 . I also tried to audit fix the vulnerabilities and end up with the following warnings,
