Python（pip）-RequestsDependencyWarning:urllib3（1.9.1）或chardet（2.3.0）不'；与支持的版本不匹配

我找到了几页关于这个问题的文章，但没有一页解决了我的问题

即使我做了一件事：

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!
  RequestsDependencyWarning)

    from urllib3.exceptions import DependencyWarning
ImportError: cannot import name DependencyWarning

但正如我解释的那样，它也给了我同样的错误

所以我做了：

sudo apt remove python-chardet

还不算他所有的家属。 重新安装后->相同：'(

我对python-pip做了同样的操作。重新安装后->同样的操作。
以下是有关

urlib3

和

chardet

所需版本的行：

/usr/local/lib/python2.7/dist包/请求/\uuu init\uuuu.py的摘录

：

    # 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)

我没有更多的想法

谢谢大家，对不起我的英语：）

您的设置是混合的（apt和

pip

都是用于安装系统范围的，这是很常见的），而且它确实与请求所需的模块的支持版本不匹配（pip v1.5.6也很旧）

请求

（哪个版本？可能是从

pip安装

中遗留下来的）需要：
urllib3:1.21.1-1.22
chardet:3.0.2-3.1.0

您有：
python-urllib3 1.9.1-3 debian包中的urllib3（1.9.1）
来自python chardet 2.3.0-1 debian包的chardet（2.3.0）

两种选择：

• 将

  requests

  降级到操作系统发行版的版本（请参阅

  apt show python requests

  ）或pypi.org上的旧版本，或

• 或者在用户级别（

  --user

  pip安装选项）或虚拟环境中安装更新的urllib3和chardet（您可以从pipy.org手动下载车轮文件，并在其上执行

  pip安装

  ，包括任何依赖项）

---

您可以在（

apt show python virtualenv

）中测试所有内容。它甚至应该在虚拟环境中为您部署一个更新的pip。在用户级别（

--user

）安装一个新的PIP10.0.1，与您的操作系统供应商的pip一起使用，但您需要对此有所了解。祝你好运

在升级到

urllib3 1.23

时遇到类似错误。安装较旧版本的

1.22

为我解决了此错误

安装较旧的

urllib3

版本时执行了以下操作：

pip卸载urllib3

pip安装urllib3==1.22

---

这是因为操作系统安装的请求模块不同，本地安装的python依赖项也不同

可以通过升级请求来解决此问题：

pip install requests

或

---

我有一个较旧版本的

请求

---

将

请求

版本从

2.19.1

更改为

2.20.1

为我解决了这个问题。

随时检查源代码是否正确，特别是当开发人员在注释中留下了清晰的说明时，就像在这种情况下一样。（可能作者应该更具体一些，并将其放在错误消息中，是的）

打开

vi/usr/lib/python2.7/site packages/requests/\uuuu init\uuuuu.py

并搜索

检查兼容性（

）

---

它对我有效。只需执行以下命令

$ sudo pip uninstall requests

$ sudo pip install requests

$ sudo pip uninstall docopt

$ sudo pip install docopt

---

这是参考资料！

我在系统更新后尝试运行

docker compose

时遇到了这个问题

有几个原因可能导致上述错误

我将在这里添加另一个解决方案，如果其他解决方案不适合某个人的特定场景，可能会有所帮助

以下组合解决了我的问题：

pip uninstall urllib3    
pip uninstall chardet
pip install requests 

---

最佳做法是确保请求及其依赖项是最新的

Python 2

$pip安装--升级请求

Python 3

$pip3安装--升级请求

---

试图将urllib3 1.25.2降级为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

一个对我有效的快速解决方案： 编辑

/usr/lib/python3.7/site packages/requests/\uuuuu init\uuuuuuuuu.py

在区块中：

# 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

#检查urllib3的兼容性。
大调，小调，patch=urllib3#u版本#noqa:F811
大调，小调，补丁=int（大调），int（小调），int（补丁）
#urllib3>=1.21.1，=21
assert minor简单您只需更新-

 pip3 install requests

只需要
sudopip安装——升级请求

如果没有sudo，您将获得被拒绝的
权限
，
如果您添加
--user
，它将不会安装到系统python中

在此之后，
pip list
不会收到requestsdependency警告

我的系统上的输出：

$ sudo pip install --upgrade requests
