requests 2.14.0 cannot be installed using pip < 8.1.2 #4006
Comments
Yeah, we can add that as a release note. That said, pip 9 is a bit newer than I thought we were going to need: @dstufft, is the |
I just bisect, and it works starting 8.1.2 (broken in 8.1.1). |
Ok, so that means it works with a version of pip that's a year old. I think I'm ok with this, though naturally the rest of the dev team should express opinions here. Generally, I'm a bit loathe to be tied down by older pips: generally speaking for most people it's easy to upgrade pip, and if it's hard to upgrade pip they're usually using a distro and so should use a virtualenv to install Requests, at which point they should just install a new pip inside the virtualenv. Any thoughts on that team? @nateprewitt @sigmavirus24 @kennethreitz? |
(For those who want the data point, pip 8.1.2 was released one year ago on Thursday). |
I just found this issue because the default pip on Travis CI is 6.x (easily fixed with the addition of |
Hrm. That's a bit hard for Travis CI to justify: the most recent 6.x release of pip is two years old, which is really a bit much! |
@Lukasa I'm opening an issue now |
I'm pretty sure the justifcation is they're Rubyists and don't think much about pip :) |
@dstufft Do you have an opinion on this, btw? |
I think everyone should always upgrade to the latest pip! Whether enough people have done that for requests to consider it reasonable to depend on it or not, I dunno. |
Ok, so I decided to get some data. I ran this query over the pip BigQuery data to see what pip version was used to install Requests over the past 30 days. Here are our answers, down to 5k downloads (I don't really care about any number lower than that):
|
So the versions that support these markers are 8.1.2, 9.0.0, and 9.0.1. Together they account for 5,667,411 of our 10,015,055 pip downloads in that time frame. Put another way, 56.6% of our downloads last month came from pip installs that are compatible with the markers. |
For some extra data points, some of the other large numbers are people using the ancient pips their distros provided. For example, pip 1.5.4 is almost entirely going to be Ubuntu Trusty, with their 1,271,017 downloads. I'm inclined not to worry about them too much: if they're installing Requests with the distro-provided pip all they're going do is break their pip. Same note with 1.5.6 (Debian Jessie), which together provide another 17% or so of downloads that are basically beyond us. |
This also broke our CI a minute ago: so is Travis gonna fix their env or are projects supposed to do an update within their Travis scripts? |
Ok, so right now with 56% of our downloaders already safe and most of the rest one |
@oberstet If it were me, I'd add a |
As a fellow maintainer of OSS projects who wants to use environment markers, <3. It seems like we should also engage with the travis folks to fix this, as that'll reduce a lot of the pain. |
@Lukasa, 8.1.1 seems to likely be coming from Ubuntu Xenial too. It seems reasonable for people to be upgrading a version of pip that in some cases is more than 3 years old. I'm on board with waiting this one out as well with the current information. We can't support legacy versions of pip forever. |
@Lukasa I'm fine with that. Travis should fix that, instead of myriads of projects, but what the hell: your advice is pragmatic! =) |
@oberstet Very much agreed, I'd prefer a world where Travis has some kind of rolling approach to pip versions, and I'm happy to work with them to make that possible if they need outside help. In the meantime, though, we shall do what we can in their absence! 😁 |
Just to point out, they are also one |
@adamjstewart Yeah, that's absolutely true, and some number of projects will probably do that. All we can do is make a decision about at what point we decide to stop supporting the older releases of I should note that Travis-CI is included in the above numbers, which means even with Travis-CI less than half of our downloads are currently affected. I don't consider that number to be at a level where I want to immediately revert this. I'm still keeping this open for discussion: I want the community and the other maintainers to weigh in. @nateprewitt and I have had our say, two maintainers have yet to get involved, and there are many more community folk who should feel free to drop in and tell us what they think. All I am saying is that right now I am open to leaving this as-is. |
Seeing this issue made me smile. :) I'm 👍 on keeping it how it is, on with progress! |
To be fair, we ran into this issue when installing a package which depends on an unbounded |
This is a common feature of shipping Requests releases: when you have a userbase as large as ours it's basically impossible to avoid breaking someone. This was a little bit bigger than I expected, I admit, but still. 😁 |
Folks, I upgraded requests using ImportError: No module named requests So I've removed the requests module multiple times and re-installed, but nothing works. I'm using python2.7 on Centos release 6.9 |
@ssmasud You must not On Linux, if you are |
ok @Lukasa so how do I make the requests module functional again? |
or in short, how do i repair python2.7 installation on centos? |
@ssmasud This is probably a more appropriate question for Ask Fedora or Server Fault, but the key step is to ask
If that doesn't fix the problem, you may also need to reinstall the system versions of request's dependencies (it's probably a good idea to do that anyway, just to be on the safe side):
|
I am not very familiar with centos, but it might be a good idea to have a look at your |
Thanks guys. Looks like |

Example with pip 6.1.1 (but same with pip 8.1.1):
So, installing requests 2.14.0 implicitly requires pip >= 9.x. Should be at least in the release note as a disclaimer, or be fixed if it's not on purpose.
