我找到了几个关于这个问题的网页，但没有一个解决了我的问题。
即使我做了：
pip show
我明白了：
/usr/local/lib/python2.7/dist-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.9.1) or chardet (2.3.0) doesn't match a supported version!

我做了什么 ：

所以我做了 ：
sudo apt remove python-chardet

以下是有关urllib3和chardet版本的行：/usr/local/lib/python2.7/dist-packages/requests/init.py的摘录：
# Check urllib3 for compatibility.

# Check chardet for compatibility.
major, minor, patch = chardet_version.split('.')[:3]
major, minor, patch = int(major), int(minor), int(patch)
# chardet >= 3.0.2, < 3.1.0
assert major == 3
assert minor < 1
assert patch >= 2
# Check imported dependencies for compatibility.
try:
check_compatibility(urllib3.__version__, chardet.__version__)
except (AssertionError, ValueError):
warnings.warn("urllib3 ({0}) or chardet ({1}) doesn't match a supported "
"version!".format(urllib3.__version__, chardet.__version__),
RequestsDependencyWarning)
我的版本是：
ii python-urllib3
1.9.1-3 all HTTP library with thread-safe connection pooling for Python
ii python-chardet
2.3.0-1
all universal character encoding detector for Python2
我没有更多的想法......
谢谢大家，对不起我的英语:)
你确实有一个混合设置（apt和pip都用于安装系统范围，这很常见），它确实与请求所需的模块支持版本不匹配（并且pip v1.5.6也很老） 。
requests（哪个版本？可能来自pip install）可能需要：
urllib3：1.21.1 - 1.22
chardet：3.0.2 - 3.1.0
你有： 来自python-urllib3的urllib3（1.9.1）1.9.1-3 debian包 chardet（2.3.0）来自python-chardet 2.3.0-1 debian包
两种选择：
requests降级到您的操作系统发行版中的版本（请参阅apt show python-requests提供的版本），要么将旧版本降级到pypi.org，或者pip install，包括任何依赖项），可以在用户级别（--user pip install选项）或virtualenv中。你可以用virtualenv（apt show python-virtualenv）测试一切。它甚至应该在其虚拟环境中为你部署一个更新的点。 possible也是在用户级别（--user）安装一个新的pip 10.0.1以及你的OS销售点，但你需要成为careful。祝好运！
所需要的只是sudo pip install --upgrade requests。
没有sudo你会得到Permission denied，如果你添加--user它将不会安装到系统python中。
在此之后，pip list没有获得RequestsDependencyWarning。
我系统上的输出：
$ sudo pip install --upgrade requests
/usr/lib/python3.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.2) or chardet (3.0.4) doesn't match a supported version!

试图将urllib3降级1.25.2降至1.24.3，但未找到后者。
$ sudo pip install -I urllb3==1.24.3
ERROR: No matching distribution found for urllb3==1.24.3
一个对我有用的快速修复：编辑/usr/lib/python3.7/site-packages/requests/__init__.py
在块中：
# Check urllib3 for compatibility.
major, minor, patch = urllib3_version # noqa: F811
major, minor, patch = int(major), int(minor), int(patch)
# urllib3 >= 1.21.1, <= 1.24
assert major == 1
assert minor >= 21
assert minor <= 24
改变了assert minor <= 24到assert minor <= 25，这解决了我的问题 - 现在。
有关于Github https://github.com/streamlink/streamlink/issues/2448的错误报告
只需更新pip：sudo pip install -U pip
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。
它可以通过升级请求来解决：
pip install requests
要么
pip3 install requests
它对我有用。只需执行以下命令。
$ sudo pip uninstall requests
$ sudo pip install requests
$ sudo pip uninstall docopt
$ sudo pip install docopt
这是参考link for detail！
升级到urllib3 1.23时面临类似的错误。旧版1.22的安装为我解决了这个错误。
是否安装了较旧的urllib3版本：
pip uninstall urllib3pip install urllib3==1.22最佳做法是确保请求及其依赖关系是最新的。
Python 2
$ pip install --upgrade requests
Python 3
$ pip3 install --upgrade requests
我有一个旧版本的requests。
将requests版本从2.19.1改为2.20.1解决了它。
在任何时候，检查源是这样的，特别是当开发人员在评论中留下明确的指令时，就像在这种情况下一样。 （也许作者应该更具体，并把它放在错误信息中，是的）
打开vi /usr/lib/python2.7/site-packages/requests/__init__.py并搜索check_compatibility(。
def check_compatibility(urllib3_version, chardet_version):
urllib3_version = urllib3_version.split('.')
assert urllib3_version != ['dev'] # Verify urllib3 isn't installed from git.
# Sometimes, urllib3 only reports its version as 16.1.
if len(urllib3_version) == 2:
urllib3_version.append('0')
# Check urllib3 for compatibility.
major, minor, patch = urllib3_version # noqa: F811
major, minor, patch = int(major), int(minor), int(patch)
# urllib3 >= 1.21.1, <= 1.24 <------------------ here
assert major == 1
assert minor >= 21
assert minor <= 24
# Check chardet for compatibility.
major, minor, patch = chardet_version.split('.')[:3]
major, minor, patch = int(major), int(minor), int(patch)
# chardet >= 3.0.2, < 3.1.0 <------------------ and here
assert major == 3
assert minor < 1
assert patch >= 2
然后，您知道urllib3和chardet兼容的版本范围。所以，你尝试：
pip uninstall urllib3
pip install urllib3==1.24
pip uninstall chardet
pip install chardet==3.0.9 # this will fail, prompting the correct versions available, so you will try to install 3.0.4 instead
在系统更新后尝试运行docker-compose <some-action>时遇到此问题。
有几个原因可能导致提到的错误。
我会在这里添加另一个解决方案，如果其他解决方案不符合他的特定情况，它可能会对某人有所帮助。
以下组合为我解决了这个问题：
pip uninstall urllib3
pip uninstall chardet
pip install requests
很简单，你只需要更新 -
pip3 install requests
