pyenv install fails at download stage (moved, reopened)

[marchoeppner]

Sorry for posting this over on the installer page... Anyway:

ORIGINAL REPORT:

When trying to install a python version through pyenv, I get the following error:

Downloading Python-2.7.8.tgz...
-> https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz
error: failed to download Python-2.7.8.tgz

BUILD FAILED (Scientific 6.5 using python-build 20141211-6-g995da2d)

ORIGINAL REPLY:
The pyenv-installer is just a single file shell script to clone pyenv from GitHub repo to local machine. It doesn't configure nothing to your shell. Here isn't right place to report the issue.

By default, pyenv install (== python-build) tries to download python archives from https://yyuu.github.io/pythons/ if it is available. Please check if you can download https://yyuu.github.io/pythons/74d70b914da4487aa1d97222b29e9554d042f825f26cb2b93abd20fdda56b557 and unset PYTHON_BUILD_SKIP_MIRROR if you cannot download it from the mirror (you're in behind some firewall?).

FURTHER COMMENTS:

• I can download the python install files as specified by the link (https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz) manually using wget, no problem
• The link suggested to try in the original reply works, but only when skipping certificate checks. Otherwise:

ERROR: certificate common name “www.github.com” doesn’t match requested host name “yyuu.github.io”.

• The variable PYTHON_BUILD_SKIP_MIRROR is unset anyway, so unsetting that doesn't do much.

So I am still where I started. Any idea what is going wrong here?

Please let me know the version of wget and curl.

[marchoeppner]

GNU Wget 1.12 built on linux-gnu.
curl 7.15.3 (x86_64-unknown-linux-gnu) libcurl/7.15.3 OpenSSL/0.9.8w

You're using very old curl/wget which don't support SNI. Setting http://yyuu.github.io/pythons as PYTHON_BUILD_MIRROR_URL might help.

In the centos 5.10,we should set the Setting http://yyuu.github.io/pythons as PYTHON_BUILD_MIRROR_URL in the .bashrc. then it runs ok. thank you very much

@yyuu Thx. Your suggestion fixed it on my box!

I encountered the same problem, and this post solved it: pyenv で BUILD FAILED

Every month or so I come up against this again when setting up a new dev machine or build server, so I'd really like to see a permanent fix for python-build. Maybe even (gasp) a Python script to download the tarball?

As of today, I'm getting this on OSX 10.11.6 (which ships with curl 7.43) and the latest pyenv from homebrew (20160726).

Installing wget1.18 didn't fix it offhand, because curl is tried first. Since I can't really risk replacing the built-in curl (I can do so using brew, but I'd rather not break some native OSX scripts that I know use curl and libcurl) and aliasing curl every time isn't an option, I just went into python-build and switched the order of wget vs curl.

Besides having this break on outdated servers (which I'll grant need upgrading anyway), it's kind of annoying for it not to work on an otherwise "regular" configuration that ships out of the box from Apple, so I really would love to see this fixed. Having SNI on the server is great, sure, and you can't fix that, but could you please consider fixing python-build in this regard?

I was facing the same issue on my ubuntu machine.
Then I just uninstalled curl and pyenv started to behave correctly again.
After installing python reinstalled curl.
But definitely need a permanent fix!
