Installing BeautifulSoup in Python: pip configuration guide

First, why install a library and then toss the agent?

Recently a lot of partners in the installation of BeautifulSoup jam, obviously knocked thepip install beautifulsoup4The result is either a tortoise-speed download or a direct error. This is a matter of fact, just like the online shopping courier is stuck in the transit center - your network line may be limited to the flow. This time you need to find a reliablehub (network equipment)This is what we often call a proxy IP.

Take a real case: last week to help colleagues with the environment, his machine could not connect to the PyPI source. After switching to ipipgo's exclusive proxy, the download speed directly soared from 5KB/s to 3MB/s. It is important to note here that choosing a proxy is not just a matter of finding a free IP address, you have to look for a proxy like ipipgo that provides a free IP address.Stabilizing long connectionsof service providers.

Second, hand to teach you to match the agent installed library

First of all, a cold knowledge: pip actually comes with proxy configuration parameters, do not have to change the system settings. If you want to use a proxy temporarily, just add the parameters directly to the command:

pip install --proxy=http://用户名:密码@ipipgo node address:port beautifulsoup4

For example, the proxy you get from the ipipgo backend is123.60.88.99:8000The account password is your registration information, so write it that way:

pip install --proxy=http://vipuser:Abc123@123.60.88.99:8000 beautifulsoup4

Here's a pitfall to watch out for:Separate settings for http and https proxies. If you encounter problems with SSL certificates, it is recommended that you switch in the ipipgo backend to theirHTTPS dedicated channel, don't harden it with a regular HTTP proxy.

Third, the permanent configuration of the agent does not scratch

Too much trouble to keep typing on the command line? Create a newpip.ini(Windows) orpip.conf(Mac/Linux), plus these:

[global]
proxy = http://vipuser:Abc123@123.60.88.99:8000

Remember to test the results after configuration:

pip config list

see thatglobal.proxy='...'That means it's done. If you don't want to use the proxy anymore, just comment out this line or delete the configuration file.

IV. First aid guide to common rollover scenes

Q: I still can't connect after configuring the proxy?
A: First check whether the proxy is expired, go to ipipgo background of theAgent Status PanelLook at the number of connections and hours of use. It is recommended to use theirDynamic Residential IPIt is less likely to be blocked than server room IPs.

Q: What should I do if the download cuts off halfway through?
A: After the pip command, add--retries=5parameter to automatically retry. If you use ipipgo'sIntelligent Routingfunction, it will automatically switch the standby node

Q: What if I have double authentication on my company's intranet?
A: Try ipipgo'sSocks5 Proxy ProgramWhen configuring, remember to change the protocol header to socks5://.

V. Why do you recommend ipipgo?

Having recently helped a dozen teams with their environments, let's be honest:
1. Their familyAPI Dynamic ExtractionReally convenient, no need to change IP manually
2. Actual measurementsresponsivenessCan be controlled within 200ms
3. ExclusiveIP Health DetectionFunction to automatically filter failed nodes

Especially when doing automated deployments with theirLong-life static IPI've been running scripts for three days straight without dropping out. It's not like some service providers, where the IP is blacklisted as you use it.

Lastly, don't try to be cheap and use free proxies, before a brother's account was blocked because of the use of wild IP. The regular service providers like ipipgo are available.Enterprise-grade encrypted transmissionIt's safe and secure without worrying about blocking, and doesn't it smell good to save time to write a few more lines of code?
