It is good as long as It will not affect jsreport's heath. I am willing to learn if anyone can explain why npm list --depth=0 emits those error messages.
Thanks a lot.

Hi! I try as you mentioned. Now it does not show "requires peer of.." warnings but with npm list --depth=0 it still showing:

Will these be ignored or need to be resolved as well?

Hi,
I was so excited to upgrade to jsreport v2. However, I got these peer dependency warnings:
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN pdfjs-dist@2.0.457 requires a peer of webpack@^2.0.0 || ^3.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN schema-utils@0.4.5 requires a peer of webpack@^2.0.0 || ^3.0.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN worker-loader@1.1.1 requires a peer of webpack@^2.0.0 || ^3.0.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.

Does v2 require ajv and webpack@^3.0.0 ?

If I try npm list --depth=0, there are even more npm ERR messages:

Please any one help how to resolve these.

Note: I am testing in: Ubuntu 14.0.4 LTS and Ubuntu 18 server LTS. Nodejs: 8.10/8.11, npm: 6.0.1

Thanks.
Trung

Ok sure. The file was sent. Thanks again. Hopefull It would not happen again. This time we are not lucky during the demo to our customer.

Yey, now it works again. Thanks a lot for your help.

As with previous resolution when I got error: error: Failed to load collection settings Error: More than 10% of the data file is corrupt, .I backed up /data/settings file then delete it then the server can start. However, I got another error when try to Run the report within localhost:5488

Do you mean to remove jsreport from the root dir level then install it again to a sub folder /home/user/myjsreportproject ?
Do I need to move the /data folder into /home/user/myjsreportproject then re-install the server there?

Just because it seems stuck at ..crawling without any further progress for some minutes so I killed the process. Now I let one console going on. What is the maximum crawling time? My PC is fast CPU and using SSD.

It is weird. I have deleted /tmp/jsreport/core/locations.json for serveral times but still can not start.

I deleted all log files then the newly one is empty no matter how many times I try to start the server.
