I installed virtualenv with pip, but I'm getting this error:
[root#szlnginx_proxy bin]# ./pip install virtualenv
Collecting virtualenv
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProtocolError('Connection aborted.', gaierror(-3, 'Temporary failure in name resolution'))': /simple/virtualenv/
I came across the same problem and I was able to resolve it by adding "nameservers" to /etc/resolv.conf. For a list of nameservers and further information on resolv.conf you can check out:
https://wiki.archlinux.org/index.php/Resolv.conf.
I also had this issue. In my case it was that I had a proxy and had not set the environment variables http_proxy and https_proxy.
If you suspect you have this issue you can look at this other answer

I am not an expert but a junior developer, and I tried to make an AI for chess, for this I went to vscode, made a folder "pychess" in vscode and on my desktop, I activate the virtual env, and then I ran pip install python-chess
and I have this :
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

kinda spent all day to figure out , changing path variables; trying different commands that I even don't remember, and I just don't know what is the problem, when I do "import chess" even if I managed to download it from windows prompt (probably I added 3 times the anaconda path to make it work), even then, it says "seems like package chess is installed on "C....blabla"" but still import chess was not working. So i deleted the chess framework downloaded from windows prompt and hoped that this time it will probably work on my terminal in vscode and inside de v environment, but I was wrong again
Please, any suggestions?
I would suggest installing openssl here
then you should make sure python is installed and run
./configure --with-openssl=/home/username/openssl
then finally run this and if there is no output you should be good
python3 -m ssl
We installed Kubeflow 1.0 on Kubernetes 1.15.16 (with Azure) and we have an issue with SSL certificate when trying to install pip package in Jupiter Notebook. The same issue also appear when trying to install directly the package from the docker container used for the Notebook Server:
In order to provide more context about the mentioned issues, here are attached some outputs that contain the errores mentioned within.
Issues found during installation of ‘nose’ package
If we try:
pip install --index-url=https://pypi.python.org/simple/ nose
Output is:
WARNING: Certificate did not match expected hostname: pypi.python.org.

Similar issue also happen using curl:
! curl https://pypi.org
Output:
curl: (51) SSL: no alternative certificate subject name matches target host name 'pypi.org'
We tried to ignore the SSL verification using
pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org
But is also raise an error:
ERROR: Could not find a version that satisfies the requirement nose (from versions: none)
ERROR: No matching distribution found for nose
We dont know where to start to solve this...
Any help would be welcome!
Thanks a lot in advance!
I got a same exception in kubeflow with Azure.
This command work for me:
pip install xgboost -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
pypi.douban.com is a chinese mirror url.
But when I go to the next step, I got the same ssl ca error when use kubeflow sdk in python. I'm still finding solution.
Since upgrading to VSCode 1.5.1 (from 1.4), I get an error message saying "connect EACCES 191.238.172.191:443" whenever starting VSCode. I've turned off the various documented privacy settings and blocked VSCode in my firewall (because my internet is usually slow and expensive). That URL seems to point to Microsoft, Brazil. Is there any way to stop VSCode 1.5.1 from trying to phone home?

What should I do ? Help me please.
You first check Proxy setting of your system.
Fire below command:
yum update
if it wont work then set proxy in File: /etc/yum.conf
And then check.
I have installed Gnumeric in CentOS 6.5, then use ssconvert command to convert .xls/.xlsx file to CSV, but I still get the following error:
$ ssconvert

configuration
Can you help me?
As this is an old question, the answer is in case someone will get the same error (like me today on CentOS 6.8), you missed to install the Sans font:
yum install gnu-free-sans-fonts
For docker alpine images this might help:
RUN apk add --update \
msttcorefonts-installer fontconfig \
ttf-opensans
