我找到了关于这个问题的几页，但没有一页能解决我的问题。

即使我做了：pip show

我得到：/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!

我所做的：pip install --upgrade chardet

但正如上面解释的那样，我也犯了同样的错误。

所以我做到了：sudo apt remove python-chardet

把他所有的家属都除名。

重新安装后-&gt；相同：'

我也为python-pip做了同样的事。重新安装后-&gt；相同。

以下是有关urllib3和chardet版本的行：

提取/usr/local/lib/python2.7/dist-packages/requests/__init__.py：# Check urllib3 for compatibility.

major, minor, patch = urllib3_version # noqa: F811

major, minor, patch = int(major), int(minor), int(patch)

# urllib3 >= 1.21.1, <= 1.22

assert major == 1

assert minor >= 21

assert minor <= 22

# 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，也为我的英语感到抱歉：)
