Installing Canvas Data CLI about canvas-data-cli HOT 14 CLOSED

Hi Tom,

Thats a weird one... can I get a bit more info from you?

Can you paste the output of the following:
npm ls -g canvas-data-cli
node -v
npm -v

Also, did you just install by doing npm install -g canvas-data-cli? I just published a new version (0.0.4) that you can try. If you just run that command again, it will update.

As far as the source of that error, it doesn't appear to be something you are doing wrong. This code is written in a newer version of javascript, es6, that we compile to an older version of javascript, es5, for compatibility. That errors seems to indicate you aren't getting the compiled version, but the untransformed source, which node can't handle yet.

Also, sorry for the rough edges, we are still working on getting a few bugs worked out which is why we haven't officially announced this yet through the Canvas Data forums, but I am glad to have one more data point to make sure we have all the kinks worked out!

Yes. I installed using this: npm install -g canvas-data-cli. I just ran it again and have the same version. 1.4.28. Still getting the error.

Hrm, have you tried using the new version of the CLI?

The only other thing I can think of is that the node version you have is fairly old. We expect node v0.12.x to work, but v0.10.x might be too old.

Just installed this morning (12/11/2015) and I'm getting the same issue.

I replaced the big try statement at the end of logger.js with:

for (var idx in levels){
    var level = levels[idx];
    Logger.prototype[level] = makeLogger(level);
}

And I seem to be off and running

from canvas-data-cli.

Okay, I figured out specifically the underlying cause of this.

The CLI uses a newer version of JS, ES2015 (aka ES6). However, ES2015 is not fully implemented in any JS runtimes so we use Babel to transpile the code that works in more runtimes. However, it still assumes some baseline features, one of those being Symbol.

Older versions of node, v0.10 and older, don't have this support and we aren't currently aren't adding a polyfill to add this support.

We actually don't officially support v0.10 in the tool and is specified by the package.json, but apparently that doesn't really do much more than warn you (and is easily missed!).

We may consider adding the polyfill in the future and officially supporting that version of node, until then though, try and upgrade and see if it causes you any issues.

Ahhh, that explains why there are 20 lines to do a for loop....

Hi Addison,

I have a need to download some of the files, so fixed this issue. It was pretty easy. I’ll explain below. Before I do, can you tell me how to download just the file or files I want? Or is this all or nothing?

Fixing /usr/lib/node_modules/canvas-data-cli/lib/logger.js:80
throw _iteratorError;

I originally began installing node.js like this:

curl --silent --location https://rpm.nodesource.com/setup | bash -

What I should have done is this:

curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -

Hi @tlamy88,

Glad to hear it worked, will close this issue. As far as downloading a single table, the newest version of the CLI has a new command fetch which will download a single table. The docs are here: https://github.com/instructure/canvas-data-cli#fetch

from canvas-data-cli.

Gentlemen,
Thanks for posting this as I ran into the same problem. My node is V0.10.13. I am running Windows 7 and cannot figure out how to update my node version. This is probably a question I should know the answer to, but I don't. Any help would be appreciated.

Hi Addison,

Logging? I see the -l switch where I can add a log level, but how can I direct it to a log file? This is how I'm running it for one table:

% /bin/canvasdata fetch -l info -c /home/username/canvas/canvas_data/config.js -t pseudonym_dim

This returned "fetch command completed successfully". I guess could redirect the output, but I was wondering if there is a method to open the log file then close it.

Thank you

from canvas-data-cli.

I don’t know how you ran the setup on windows Chkay, but this is what I did wrong on Linux. I ran setup like this:

curl --silent --location https://rpm.nodesource.com/setup | bash -

This is how I fixed it:

I uninstalled nodejs and ran the 4.x setup like this:

curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -

Tom,
Thanks, and I need to change that chkay thing. I used the MSI and tried both their 4 and 5 versions. It just occured to me that the I may have old files hanging around in the ever helpful Windows system. I will check that.

from canvas-data-cli.

I just installed v4.3.2 LTS on my Windows 7 machine using the msi file.
I used a command prompt to go to C:\Program Files\nodejs
In that dir, I ran “node -v” and got v4.3.2.
I then ran “npm -v” and got 2.14.12.
Are you in the right directory?
