zak100 Posted December 24, 2020 Author Share Posted December 24, 2020 Hi, Thanks for your response. I can't install web3.js on my ubuntu machine. I am getting "1 severe vulnerability problem". Is there any way to solve this problem by directing the link of web3 to a python repository? What is the meaning of the post in my first message? Zulfi.

fiveworlds Posted December 24, 2020 Share Posted December 24, 2020 Quote I am getting "1 severe vulnerability problem". Strange I didn't get any error when installing with python3 and pip. Quote What is the meaning of the post in my first message? That is a CDN for downloading JavaScript to run web3 on a webpage. Similar to jQuery you just need to use the <script> tag. But it won't be available to Python or NodeJS. 1 Link to comment Share on other sites More sharing options...
zak100 Posted December 25, 2020 Author Share Posted December 25, 2020 Hi, Sorry I don't mean web3.py. <That is a CDN for downloading JavaScript to run web3 on a webpage. Similar to jQuery you just need to use the <script> tag. But it won't be available to Python or NodeJS.> This is what I am talking about. By web3 I mean web3.nodejs. Its a javascript stuff. Kindly look at my following are posts: reddit web_js installation reddit_Ubuntu ethereum_stack exchange Sorry nobody is able to solve my 1 severe vulnerability problem related web3.nodejs Zulfi.

zak100 Posted December 26, 2020 Author Share Posted December 26, 2020 Hi, @Ghideon very good link. This can be useful for object oriented programming. @fiveworlds: Thanks, you have solved my problem. Actually it was related to python. When I installed web3.py using pip command the "no web3 module error" went away. Zulfi. Link to comment Share on other sites More sharing options...
