Pip: Unable to upgrade pip or install packages

[ampersamd]

• Pip version: pip 8.0.3
• Python version: 3.4.3
• Operating system: OS 10.13

Description:

I was trying to install beautifulSoup4, but I keep running into an error claiming there is a problem with the ssl certificate.

$ pip install beautifulsoup4
Could not fetch URL https://pypi.python.org/simple/beautifulsoup4/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:600) - skipping
  Could not find a version that satisfies the requirement beautifulsoup4 (from versions: )
No matching distribution found for beautifulsoup4

I saw a few others having a similar issue that they were able to work around by nameing pypi.python.org as a trusted host. I tried that, but to no successful.

$ pip install --trusted-host pypi.python.org beautifulsoup4
Collecting beautifulsoup4
  Could not fetch URL https://pypi.python.org/simple/beautifulsoup4/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:600) - skipping
  Could not find a version that satisfies the requirement beautifulsoup4 (from versions: )
No matching distribution found for beautifulsoup4

I also found I am unable to upgrade pip. When trying to upgrade pip, I see that requirements are already up to date, although when running pip --version I see that I'm a few versions behind.

$ pip install -U pip
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:600) - skipping
Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages

$ pip --version
pip 8.0.3 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages (python 3.4)

Anyone experience similar issues? Any suggestions?

What happens when you add the -vvv verbosity flag to get more detailed error messages? I wonder whether https://mail.python.org/pipermail/python-announce-list/2018-April/011885.html is affecting you.

[ampersamd]

@brainwane Results of adding -vvv. It's definitely failing when trying to make a connection to pypi.python.org

$ pip install -U pip -vvv

[brainwane]

I was right. :) You're affected by the TLS 1.0/1.1 deprecation mentioned in https://mail.python.org/pipermail/python-announce-list/2018-April/011885.html . Solution: upgrade pip using the bootstrapping method described in:

https://pip.pypa.io/en/latest/installing/

[ampersamd]

@brainwane Looks like you are indeed correct. I'm using TLS 1.0.
However, I'm still running into issues upgrading. I successfully upgraded my Python version to 3.6.5. Following the bootstrapping instructions you linked, it looks like pip 10.0.0 was installed but I'm still running pip 8.0.3. Not sure how I can force pip 10.0.0

Upgrade pip3 using.

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

Instead of pip install -U pip

For pip2
pip2 install --upgrade pip

[ampersamd]

@jackton1 The first suggestion did the trick. Many thanks!

[brainwane]

Great. :) If you think the problem's solved, please close the issue @ampersamd.

[pradyunsg]

Thanks @brainwane and @jackton1! :)

Hi folks,

I met the similar issue while trying to install opencv-python, and others package install success.

• OS: Windows10
• python: 3.7.0
• pip: 10.0.1

The package can be found via pip search, and the install error message is:

Could not find a version that satisfies the requirement opencv-python==3.4.1.15 (from versions: )
No matching distribution found for opencv-python==3.4.1.15

adding the -vvv output is:

Anyone have any suggestions?

[pradyunsg]

Yeah. It seems that OpenCV hasn't released any wheels for Python 3.7 yet, hence the error message.
