jshint error:can't open *.json

[Max Hsu]

I follow CODAP Developer Guide to set up development environment. After run code below,

• npm run build:bundle

it echoes words like this:

•  eslint *.js apps && jshint -e .json *.json apps –verbose
• ERROR: Can’t open *.json

Could you tell me why and how to fix it?

Hello Max,
<div style=”color: #222222; font-family: arial, sans-serif; font-size: 12.8px;”>I am sorry you are having difficulty installing the CODAP development environment on your computer. Its a little difficult for me to understand what may have caused this failure. Had you run “npm install” prior to running “npm run build:bundle”. The install instructions recommend installing cygwin or a shell with similar functionality on Windows systems. This may help. Also, you may wish to try running “yarn” instead of “npm install” since it is more precise on versioning. To install “yarn”, run “npm install -g yarn”.</div>

Many interesting things can be done by writing a CODAP plugin. You can integrate new data sources or create new data visualizations this way. Developing a plugin does not require setting up a full CODAP development environment.

(my previous post came out somewhat garbled for some reason. What follows is a cleaned up version.)

I am sorry you are having difficulty installing the CODAP development environment on your computer. Its a little difficult for me to understand what may have caused this failure. Had you run “npm install” prior to running “npm run build:bundle”. The install instructions recommend installing cygwin or a shell with similar functionality on Windows systems. This may help.

We do not see the issue you are seeing when we execute the install procedure on our Windows machines, here. What version of Windows are you using?
