Description

The question is how to launch wechaty in Ubuntu Server. I have read the dockfile, which using google's source to install chrome drivers. But my server is now behind the wall.

I also tried with my machine oversea, but it fails too.

  apt-utils \
  chromium \
  google-chrome-stable \
  vim \
  xvfb

W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wron
g sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

OS

@zixia Would you have a look? I have tried to install the dependencies. The service is running great with my Macbook, now, I consider to migrate it into cloud. Thanks in advance.

hi @Samurais ,

I have some suggestions to you:

1. first, I had the same issue on aliyun hk server before: those servers can't make connection to some google servers. change your server from aliyun to digitalocean/linode might help. (I had put links in README, which can gain free credit for both of us if you follow that link)
2. second, please have a look at ChromeDriver PATH problem #30 , if you did not put chrome into your PATH.
3. third, do not use phantomjs now, because there has some bug which cause the wx app angular environment not right. use chrome/chromium instead.
4. at last, your philly-wechat is great, I love ai bot. thanks for using wechaty. :)

please let me know if those suggestions could help you solve the problem, and feel free to post here if you still have problems with wechaty cloud installation.

good luck!

Thanks, I would switch to digitalocean soon. philly is a logic server, but instead of using api.ai/wit.ai, I am going to use superscript currently. philly-wechat is the channel to integrate with wechat. I am also working on other integrations as well, such as gitter.

wechaty is great. 👍
Update here when solving the problem.

I do not understand what philly do right now, but it seems philly is doing something overlap with Microsoft Bot Framework.

M$ Bot Framework has a powerful bot builder framework, it's a connector/router for messages between skype/wechat(official account)/facebook/slack/etc..., with a clean nodejs SDK: https://github.com/Microsoft/BotBuilder/tree/master/Node/examples

Also I'm a big LUIS.ai fan. :)

[hailiang-wang]

I did some investigation with Botframework, but it does not mature in some ways.

On the other way, I would like to implement something lightweight to build the conversations channels but collect the data on our side because of our business reason.

Solution

Finally, the app run in Ubuntu Server successfully.

apt-get update -q 
sudo apt-get install chromium-browser  xvfb libpango1.0-0 fonts-liberation libappindicator1 libdbusmenu-glib4 libdbusmenu-gtk4   libindicator7 indicator-application
apt-get install -f gconf-service gconf2-common  libgconf-2-4 gconf-service-backend

wget -c https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb
nohup Xvfb :0 -ac -screen 0 1024x768x24 &
export DISPLAY=0:0
node app.js

congratulations!

how could you fix this, did you switched the server out of aliyun/qqcloud?

and it would be great if you cloud add a Wechaty Badge to your README :)

[hailiang-wang]

The server is in aliyun, behind the wall.
Of course, I can add the Badge, thanks a lot.
