QUESTION
I picked up a 4 year old project written in Ruby 2.1.3
and Rails 4.1.8
.
Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20
as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57
and brew install openssl@10
.
I could then install mysql2
with by passing the correct libraries to it:
gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include
Everything works locally, all good.

You are loading the mysql2 gem, but indicating to ActiveRecord that you want to use a connection via the mysql gem.

ANSWER
Answered 2019-Jul-03 at 12:33The root of the problem seems to be bundler. What operating system and Ruby version are you using? It may be a problem with old OpenSSL library, so you can not install bundler and everything after it.
If you are using jRuby (your gem list
output tells so), your problem seems to be the same as described in link. And there is a solution as well.
Maybe you forgot to set 2.1.2
version of ruby as global? (rbenv set global 2.1.2
)
QUESTION
I'm getting started with reptiles and trying to perform a second crawling exercise based on Feedly(Feedly RSS is the first time I think): it don't open website to see the news, just the title, source link and update time)
This is my code, the first tried with python.
I was thinking that I might need crawling on my subscribe root websites and might need to write a Scrapy script and use MangoDB or Excel/CSV for this?
In my this case, I was even think that I should develop a macOS App to show the crawling result and I was designed the App UI, or use Python QT and learned QT。
I tried to print the links and the title first, but Feedly should tap twice that show Source page,so i choose Feedly‘s entry.
Python code:
...ANSWER
Answered 2019-Jun-22 at 20:08I'm actually the author of the CSS implementation (Soup Sieve) in Beautiful Soup 4.7+.
The reason it is failing is because you are not following the CSS specification. Now, I'm not aware of exactly what you are trying to target, so I cannot suggest working selectors, but I can explain why Soup Sieve is failing for you.
The error in your example #.*?\=_16b.*?\:2.*?\:d02fd57c_entry_title
is failing because it sees an id token #
, but is not followed by an id. Instead it sees the start of a class .
, and that is also invalid as it is followed by *
. In short, there is a lot wrong with the selector, but the error is just reporting the first.
You will need to use CSS escapes for invalid characters in ids, classes, etc. If we try to run such a selector through a browser, you'll see that it fails as well:

I am trying to obtain the odds of the link and I get an error. DO you know what I am doing wrong?
Thank you
...ANSWER
Answered 2019-May-18 at 22:19It looks like you have wrong char between #tournamentTable
and td[xodd]
. It may look like space but it has code \x1b
. You may try to delete this char and put space again.
I can run your code without this error. But this page uses JavaScript to get data and BS
can't run JavaScript. You may need Selenium to control web browser which can run JavaScript and you can get HTML with data.
Or you can use DevTool in Chrome/Firefox to check if JavaScript read data from some url and read data from the same url.
