 urllib3 supports features left out of urllib and urllib2 libraries. 

 * Re-use the same socket connection for multiple requests (HTTPConnectionPool and HTTPSConnectionPool) (with optional client-side certificate verification). 
 * File posting (encode_multipart_formdata). 
 * Built-in redirection and retries (optional). 
 * Supports gzip and deflate decoding. 
 * Thread-safe and sanity-safe.

我有另一个具有相同铬浏览器 chromedriver 版本的设置，但没有发生错误.我还能检查什么?

I have another setup with same chromium-browser chromedriver versions and the error doesn't happen. What else could I check?

还有什么建议吗?

在没有发生问题的环境中，pip 版本不一样.

On the environment where the issue doesn't happen the pip version isn't the same.

pip v1.5.4 代替 pip install --upgrade pip==1.5.4现在卸载 pip 18.1 并重新安装我的 pip 包.

pip v1.5.4 instead pip install --upgrade pip==1.5.4 Now uninstalling pip 18.1 and reinstalling my pip packages.

如果您想再次恢复，请安装回最新版本的pip

To install back the latest version of pip if you want to revert again

python -m pip install --upgrade pip

还注意到，在正常运行的机器上，我的 GCC 版本略有不同

Also noted that on the functioning machine I have a slightly different version of GCC

gcc --version
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

已解决

我必须从全新的 Xubuntu 设置开始并运行

Resolved

I had to start from a fresh Xubuntu setup and ran 

sudo pip install -U urllib3

推荐答案

潜在的解决方案:

1- 尝试升级 urllib3 版本，根据:https://github.com/kubernetes-client/python/blob/master/requirements.txt

1- Try upgrading the version o urllib3, seems like the version of urllib3 is old according to: https://github.com/kubernetes-client/python/blob/master/requirements.txt

确保 urllib3 的版本为 1.16 或更高.在这里，您可以找到设置:https://launchpad.net/ubuntu/+source/python-urllib3/1.21.1-1

Make sure the version of urllib3 is 1.16 or more. Here, you can find the setup: https://launchpad.net/ubuntu/+source/python-urllib3/1.21.1-1

2-更新python版本:

2- Update the version of python:

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update 
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
sudo update-alternatives --config python3
