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

Question

我找到了几页关于这个问题的内容，但其中 none 解决了我的问题。

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!
  RequestsDependencyWarning)

  File "/usr/local/lib/python2.7/dist-packages/requests/__init__.py", line 90, in <module>
    from urllib3.exceptions import DependencyWarning
ImportError: cannot import name DependencyWarning

我做了什么：

pip install --upgrade chardet

但是正如上面所解释的那样，它给了我同样的错误。

所以我做到了:

sudo apt remove python-chardet

并卸载他所有的依赖项。重新安装后 -> 相同 :'(

我为 python-pip 做了同样的事情。重新安装后->相同。
以下是关于需要 urllib3 和 chardet 版本的行： /usr/local/lib/python2.7/dist-packages/requests/__init__.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

我没有更多的想法了...

Answer 1

您确实有一个混合设置（apt 和 pip 都用于在系统范围内安装，这很常见），它确实与所需模块的受支持版本不匹配按要求（pip v1.5.6 也很旧）。

requests（哪个版本？可能是 pip install 遗留下来的）需要：
urllib3: 1.21.1 - 1.22
chardet: 3.0.2 - 3.1.0

您有：
urllib3 (1.9.1) 来自 python-urllib3 1.9.1-3 debian 软件包
来自 python-chardet 2.3.0-1 debian 软件包

的 chardet (2.3.0)

两个选项：

要么将 requests 降级到 OS 发行版的版本（查看 apt show python-requests 的可用版本），要么将 pypi.org 的旧版本降级，或
或安装更新的 urllib3 和 chardet（您可以从 pipy.org 手动下载 wheel 文件并对它们执行 pip install，包括任何依赖项），或者在用户级别（ --user pip 安装选项）或在 virtualenv 中。

您可以在 virtualenv (apt show python-virtualenv). It should even deploy a newer pip for you inside of its virtual envs. It is also to install a newer pip 10.0.1 at the user-level (--user) alongside your OS-vendored pip but you need to be careful 中测试所有内容。祝你好运！

Answer 2

升级到 urllib3 1.23 时遇到类似错误。安装旧版本 1.22 为我解决了这个错误。

是否按照以下步骤安装了旧的 urllib3 版本：

pip uninstall urllib3
pip install urllib3==1.22

Answer 3

这是因为 OS 安装的请求模块与您本地安装的 python 依赖项不同。

可以通过升级请求解决：

pip install requests

或

pip3 install requests

Answer 4

我有一个旧版本 requests。

将 requests 版本从 2.19.1 更改为 2.20.1 为我解决了这个问题。

Answer 5

在任何时候，检查来源都是正确的方式，特别是当开发人员在评论中留下明确说明时，就像在这种情况下一样。（也许作者应该更具体一些，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

那么，你就知道urllib3和chardet兼容的版本范围了。所以，你试试：

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

Answer 6

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

Answer 7

我在系统更新后尝试运行 docker-compose <some-action> 时遇到了这个问题。

有几个原因可能导致上述错误。

我会在这里添加另一个解决方案，如果其他解决方案不适合他的特定场景，也许它会对某人有所帮助。

以下组合解决了我的问题：

pip uninstall urllib3    
pip uninstall chardet
pip install requests

Answer 8

最佳做法是确保请求及其依赖项是最新的。

Python 2

$ pip install --upgrade requests

Python 3

$ pip3 install --upgrade requests

Answer 9

试图将 urllib3 1.25.2 降级到 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

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

将 assert minor <= 24 更改为 assert minor <= 25，这暂时解决了我的问题。

上有错误报告

Answer 10

简单你只需要更新-

 pip3 install requests

Answer 11

只需要sudo pip install --upgrade requests。

没有 sudo 你会得到 Permission denied, 如果你添加 --user 它不会安装到系统 python.

在此之后，pip list 不会收到 RequestsDependencyWarning。

我系统上的输出：

$ sudo pip install --upgrade requests

Answer 12

只需更新 pip：sudo pip install -U pip

Answer 13

我收到此错误运行虚拟 python 环境 (Home Assistant) 并且上述建议对我不起作用，因为用户 (homeassistant) 没有密码或 sudo权利。

这种情况下的解决方案是简单地停用venv环境，然后删除虚拟环境目录并重新创建虚拟文件夹。

要停用 python3 venv，只需在虚拟环境树中的任意位置执行 'deactivate' bash 命令即可。

Answer 14

我用

解决了这个问题

pip install --upgrade requests==2.20.1

如果您看到如下版本不兼容的消息，您应该尝试其他版本。所有版本为：here

ERROR: docker-compose 1.24.1 has requirement requests!=2.11.0,!=2.12.2,!=2.18.0,<2.21,>=2.6.1, but you'll have requests 2.21.0 which is incompatible.

Answer 15

我用这个命令解决了这个问题

pip install --upgrade requests==2.20.1

如果您看到如下版本不兼容的消息，您应该尝试其他版本。所有版本为：here

ERROR: docker-compose 1.24.1 has requirement requests!=2.11.0,!=2.12.2,!=2.18.0,<2.21,>=2.6.1, but you'll have requests 2.21.0 which is incompatible.

Answer 16

我在使用以下 urllib3 和 chardet 版本时遇到了同样的问题。

OS : Ubuntu 18.04

urllib3 : 1.25.6

chardet : 3.0.4

错误：/usr/lib/python3/dist-packages/requests/init.py:80: RequestsDependencyWarning: urllib3 (1.25.6) 或 chardet (3.0.4) 与受支持的不匹配版本！ RequestsDependencyWarning)

解决方案：更新 'requests' 包。

$ pip3 安装请求

Answer 17

对我来说，修复是：

pip uninstall urllib3    
pip uninstall chardet
pip install requests

堆栈：

Centos 7.6.1810

docker-compose 1.24.1 build 4667896（docker-compose 日志给我警告）

python 2.7.5

点 8.1.2

Answer 18

在我的例子中，chardet 包有问题。我安装了两个版本（2.3.0 和 3.04），出于某种原因 python 加载了旧版本。我的解决方案是手动删除包：

rm -rf /usr/lib/python2.7/site-packages/chardet*

然后重新安装

pip install chardet

如果还没有更新 urllib3 并请求到最新版本

pip install --upgrade urllib3
pip install --upgrade requests

Answer 19

试试这两个命令，希望你能成功。

sudo python3 -m pip install --upgrade --user urllib3==1.24.3

sudo apt-get update
