Pip: Could not fetch URL... problem confirming the ssl certificate

Created on 14 Apr 2018 · 18Comments · Source: pypa/pip

Pip version: 9.0.1
Python version: 3.5.0
Operating system: MacOS 10.13.4

Description:

pip failing with SSL error in past week or so. Similar to issue #5063, but raising specific error.

What I've run:

`pip list -o`
# returns, e.g.:
`Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:646) - skipping`

`pip install --upgrade pip setuptools`
# returns
`Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:646) - skipping
Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages
Could not fetch URL https://pypi.python.org/simple/setuptools/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:646) - skipping
Requirement already up-to-date: setuptools in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages`

In virtual environment (created with `venv`) pip (9.0.3) works correctly:
`python -m pip list -o
pip (9.0.3) - Latest: 10.0.0 [wheel]
You are using pip version 9.0.3, however version 10.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.`

FIXED (work-around): installed Python 3.6.5 with pip 9.0.3. Updated pip to 10.0.0. Ran Install Certificates.command.

For anybody who is still getting the same issue, upgrading pip manually works (in a venv, at least):

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

osx broke tls for pip < 9.0.3 a few days ago, which is why the emergency releases of pip 9.0.3 where made

Thank you, Ronny. Is there an easy way to keep up-to-date on such things -- new releases, emergency releases? By email, perhaps?
I am new at this. Should I close this issue?

Using libraries.io helps with keeping track of releases of projects you care about.

You might also want to subscribe to the pypi-announce mailing list https://mail.python.org/mm3/mailman3/lists/pypi-announce.python.org/ for updates about future changes to PyPI.

@drastorguev The linked command fails on Windows 7:

'curl' is not recognized as an internal or external command operable program or batch file.

Upgrading MacOS to High Sierra and then upgrading pip to the latest version solved it.

I just installed Python 2.7.15 in El Capitan and I still get this error
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.",)) - skipping

the same issue ,
python3 -m pip install numpy

You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

You will want to upgrade your OS as well, from the comment above it sounds like the OS is at fault.

I was getting this error too. I tried many suggestions, dint work. This one worked..

check which python & its ssl version
python -c "import ssl; print(ssl.OPENSSL_VERSION)"
OpenSSL 1.0.2f 28 Jan 2016

python3 -c "import ssl; print (ssl.OPENSSL_VERSION)"
OpenSSL 0.9.8zh 14 Jan 2016

check pip
pip --version
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)

upgrade pip for python3
curl https://bootstrap.pypa.io/get-pip.py | python3

pip --version
pip 10.0.1 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/pip (python 3.5)

which pip
/Library/Frameworks/Python.framework/Versions/3.5/bin/pip
I was able to install python pip packages after this, SSL cert problem solved

This worked for me for packages that didn't update to the latest TLS version:
pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org

omg you saved my life man. I was literally trying to solve this issue for three hours. I even called Apple customer service and they didn't know how to help me. Upgrading pip was the solution all along. Thank you a million times.
