Node, 5.1.18-prerelease: TypeError: Buffer.alloc is not a function

[Alex Hough]

@jeremy,

Is this the best place to post the below?

I have updated TW on node

users-mbp-2:TW-Node alexhough$ tiddlywiki --version

5.1.18-prerelease

Then I tried

users-mbp-2:TW-Node alexhough$ tiddlywiki mynewwiki --init server

The output was

$:/core/modules/utils/filesystem.js:60

fileBuffer = Buffer.alloc(FILE_BUFFER_LENGTH);

                    ^

TypeError: Buffer.alloc is not a function

    at $tw.boot.executeNextStartupTask (/Users/alexhough/TiddlyWiki5-master/boot/boot.js:2111:21)

users-mbp-2:TW-Node alexhough$

The new material on the pre-release looks very interesting, I have a new project and want to start with state of the art TW...

best wishes

Alex

Alex,

It may be best for pre-release feedback to be placed in the TiddlyWikiDev group.

Far be it me to tell you what to do but unless you need a feature in an impending release N-1 is the best, or the latest public release (older than a few weeks), especially when the next one foreshadowed is but an incremental release.

I say this based on the reliability of tiddlywiki upgrades and the likelyhood that undetected errors will be fixed soon after a release. TiddlyWiki 5.1.16 was quickly followed by 6.1.17 If you install the 5.1.18 pre-lrelease you may find along comes 5.1.19 quickly followed by 5.1.20 and their is less gaurentee of an effective upgrade from the pre-release. In effect you may find yourself 3 versions behind in a tick

Yes, install it along side your working one, yes please provide feedback, as you are doing, but consider avoiding using it in "production".

Best wishes

Tony

I think there were some changes to the Buffer module but that was a while ago. Are you using an older version of node? You can tell by opening a terminal and typing 'node -v'. If you have a version older than 6 you should probably consider updating.

[Alex Hough]

thanks Jed and Tony,

I like using the latest version, and want to help iron out problems.

I'm pretty certain I'm running an old version of node, thanks Jed!

UPDATE

The listen command still doesn't work, server does though.

Error: Unknown command: listen

Serving on 127.0.0.1:8080

maybe the docs are ahead of the code in this instance

Hi Alex

Did you definitely download the new branch, rather than the default master branch? Check my original post for links

Best wishes

Jeremy

Hi Alex

I followed the documentation on installing pre-release on node.

OK, the difference here is that the new code is in a different branch, so you'll need to download it from this URL, rather than the one in the instructions:

https://github.com/Jermolene/TiddlyWiki5/tree/http-server

Best wishes
