## Requirements:
|
||||
|
||||
* Ubuntu/Debian:
|
||||
```
|
||||
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
|
||||
libreadline-dev libsqlite3-dev wget curl llvm
|
||||
```
|
||||
|
||||
* Fedora:
|
||||
`yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel`
|
||||
|
||||
* Mac:
|
||||
```bash brew install readline; brew link readline; pyenv install 2.7.5```
|
||||
|
||||
|
||||
**NOTE**: `libssl-dev` is required when compiling Python, installing `libssl-dev` will actually install `zlib1g-dev`, which leads to uninstall and re-install Python versions (installed before installing `libssl-dev`). On Redhat and derivatives the package is named `openssl-devel`.
|
||||
|
||||
|
||||
## Removing a python version
|
||||
|
||||
rm -rf .pyenv/versions/2.7.5
|
||||
|
||||
## Installing a 32 bit python on 64 bit Mac OS X (this will *not* work on Linux)
|
||||
|
||||
CONFIGURE_OPTS="--with-arch=i386" CFLAGS="-arch i386" LDFLAGS="-arch i386" python-build options
|
||||
|
||||
## Installing a system-wide Python
|
||||
If you want to install a Python interpreter that's available to all users and system scripts (no pyenv), use `/usr/local/` as the install path. For example:
|
||||
|
||||
sudo python-build 3.3.2 /usr/local/
|
||||
|
||||
## Make your pythons a little faster
|
||||
You can set your CFLAGS to accepted safe values to help get a little more speed.
|
||||
|
||||
CFLAGS='-g -O2'
|
||||
|
||||
## Build failed - bad interpreter: Permission denied
|
||||
|
||||
If you encounter this error while installing python and your server is a VPS, the **/tmp** directory where python-build download and compile the packages is probably mounted as **noexec**. You can check with your hosting provider if wether they provide a way to bypass this protection.
|
||||
|
||||
If the answer is no, just set the **$TMPDIR** environment variable to wherever you have a write + execution rights. For example:
|
||||
|
||||
export TMPDIR="$HOME/src"
|
||||
|
||||
Please note you'll have to do it every time you'll want to install a new version of python unless you write this command in your `~/.bashrc`.
|
||||
|
||||
## Build failed
|
||||
|
||||
If you've got something like that:
|
||||
|
||||
```
|
||||
$ pyenv install 2.7.5
|
||||
Downloading http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz...
|
||||
Installing yaml-0.1.4...
|
||||
|
||||
BUILD FAILED
|
||||
```
|
||||
|
||||
please, be sure to have "make" installed (```$ sudo apt-get install make```). On Ubuntu Server, by default, it doesn't.
|
||||
|
||||
If you've got something like that:
|

|

Installing Python-2.7.7...
|
||||
|
||||
ERROR: The Python zlib extension was not compiled. Missing the zlib?
|
||||
|
||||
Please consult to the Wiki page to fix the problem.

|

BUILD FAILED
|

```
|
||||

You could try this:
|
||||
|
||||
```
|
||||
CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7
|
||||
```
|
||||
|
||||
It works for me on osx 10.10 DP.

|

On Mac OS X 10.9 and 10.10 you may need to set the CFLAGS environment variable when installing a new version in order for configure to find the zlib headers (XCode command line tools must be installed first):
|
||||
|
||||
```
|
||||
CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7
|
||||
```
|
||||
|
||||
## python-build: definition not found
|
||||
|
||||
To update your python-build definitions:
|
||||
|
||||
If you have python-build installed as an pyenv plugin:
|
||||
|
||||
$ cd ~/.pyenv/plugins/python-build && git pull
