Python (pip) - RequestsDependencyWarning: urllib3 (1.9.1) or chardet (2.3.0) doesn't match a supported version

What I did :

pip install --upgrade chardet

but as explain up, it gaves me the same error.

但作为解释，它给了我同样的错误。

so I did :

所以我做了 ：

sudo apt remove python-chardet

and unistalling all his dependecies. After I reinstall it -> the same :'(

并解除他所有的依赖。在我重新安装它之后-> 相同:'(

I did the same for python-pip. After reinstalling it -> the same.

You do have a mixed setup (both aptand pipwere used to install system-wide, which is common), and it indeed doesn't match the supported versions of modules required by requests (and pip v1.5.6 is also quite old).

你有一个混合的设置（包括apt和pip用来安装系统范围内，这是常见的），它确实不匹配，请求所需模块的支持版本（和PIP v1.5.6也相当大）。

The requests(which version? likely leftover from pip install) requires:
urllib3: 1.21.1 - 1.22
chardet: 3.0.2 - 3.1.0

在requests（？哪个版本可能从剩下的pip install）要求：
urllib3：1.21.1 - 1.22
chardet的：3.0.2 - 3.1.0

You have:
urllib3 (1.9.1) from python-urllib3 1.9.1-3 debian package
chardet (2.3.0) from python-chardet 2.3.0-1 debian package

你有：
urllib3 (1.9.1) from python-urllib3 1.9.1-3 debian package
chardet (2.3.0) from python-chardet 2.3.0-1 debian package

Two options:

两种选择：

• either downgrade requeststo the version from your OS distribution (see what's available with apt show python-requests), or older versions at pypi.org, or

• or install newer urllib3 and chardet (you can download the wheel files manually from pipy.org and do pip installon them, including any dependencies), either at user level (--userpip install option) or in a virtualenv.

• requests从您的操作系统发行版降级到版本（查看apt show python-requestspypi.org 上的可用版本）或旧版本，或

• 或者pip install在用户级别（--userpip install 选项）或在 virtualenv 中安装更新的 urllib3 和 chardet（您可以从 pipy.org 手动下载轮文件并对其进行处理，包括任何依赖项）。

You can test everything in a virtualenv(apt show python-virtualenv). It should even deploy a newer pip for you inside of its virtual envs. It is also possibleto install a newer pip 10.0.1 at the user-level (--user) alongside your OS-vendored pip but you need to be carefulabout that. Good luck!

您可以在virtualenv( apt show python-virtualenv) 中测试所有内容。它甚至应该在其虚拟环境中为您部署一个更新的 pip。也可以在用户级别 ( --user) 与操作系统供应商的 pip 一起安装更新的 pip 10.0.1，但您需要注意这一点。祝你好运！

This is because of different requests module installed by the OS and the python dependencies for your local installation.

这是因为操作系统安装了不同的请求模块以及本地安装的 python 依赖项。

It can be solved by upgrading requests:

可以通过升级请求来解决：

pip install requests

or

或者

pip3 install requests

Faced similar error when upgraded to urllib3 1.23. Installation of older version 1.22resolved this error for me.

升级到urllib3 1.23. 旧版本的安装1.22为我解决了这个错误。

Did following to install the older urllib3version:

执行以下操作来安装旧urllib3版本：

1. pip uninstall urllib3
2. pip install urllib3==1.22

1. pip uninstall urllib3
2. pip install urllib3==1.22

The best practice would be to make sure requests and its dependenciesare up to date.

最佳实践是确保请求及其依赖项是最新的。

All that's needed is sudo pip install --upgrade requests.

所需要的只是sudo pip install --upgrade requests.

Without sudo you'll get Permission denied, and if you add --userit won't install into system python.

没有 sudo 你会得到Permission denied，如果你添加--user它就不会安装到系统 python 中。

After this, pip listdoes not get a RequestsDependencyWarning.

在此之后，pip list不会得到 RequestsDependencyWarning。

$ sudo pip install --upgrade requests

I had an older version of requests.

Changing requestsversion from 2.19.1to 2.20.1solved it for me.
