copy pyenv installation onto other nodes

the step Im working on copying pyenv installation.

1. zip -r /tmp/my.pyenv.zip ~/.pyenv/
2. scp /tmp/my.pyenv.zip new:/tmp/
3. new# unzip /tmp/my.pyenv.zip -d ~/

1. zip -r /tmp/my.pyenv.zip ~/.pyenv/

2. scp /tmp/my.pyenv.zip new:/tmp/

3. new# unzip /tmp/my.pyenv.zip -d ~/

seems it’s simple, after setting env. it failed.

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"

eval "$(pyenv init -)"

export PYENV_ROOT="$HOME/.pyenv"

export PATH="$PYENV_ROOT/bin:$PATH"

eval "$(pyenv init -)"

the problem is :

# pyenv init -
pyenv: no such command `init'

1 2	# pyenv init - pyenv: no such command `init'

well after checking, it was the problem that ~/.pyenv/libexec was not in the $PATH.

comparing the src and dest env.:

# ls -altr ~/.pyenv/bin/
total 12
-rwxr-xr-x. 1 root root 731 Dec 28 09:16 python-local-exec
lrwxrwxrwx. 1 root root 16 Dec 28 11:04 pyenv -&gt; ../libexec/pyenv
drwxr-xr-x. 12 root root 4096 Mar 29 08:54 ..
drwxr-xr-x. 2 root root 4096 Mar 29 09:45 .

drwxr-xr-x 2 root root 4096 Mar 29 09:44 .

# ls -altr ~/.pyenv/bin/

total 12

-rwxr-xr-x. 1 root root 731 Dec 28 09:16 python-local-exec

lrwxrwxrwx. 1 root root 16 Dec 28 11:04 pyenv -> ../libexec/pyenv

drwxr-xr-x. 12 root root 4096 Mar 29 08:54 ..

drwxr-xr-x. 2 root root 4096 Mar 29 09:45 .

# ls -altr ~/.pyenv/bin/

total 12

-rwxr-xr-x 1 root root 731 Dec 28 09:16 python-local-exec

drwxr-xr-x 12 root root 4096 Mar 29 09:02 ..

lrwxrwxrwx 1 root root 2695 Dec 28 09:16 pyenv

drwxr-xr-x 2 root root 4096 Mar 29 09:44 .

the problem is that pyenv is now a binary, not sym.link instead.

FIX:
1. using zip -y or –symlinks option on backup.
2. or after unzip, remove pyenv binary under ~/.pyenv/bin/, install sym-link.

Well, it’s a classic issue on Acroread.

There’s no fix for even we do not have new Acroread version for linux.

But w/r provided in comment #21:

easy_install scapy failed

Run

# yum -y install tcpdump graphviz ImageMagick

root cause is:
On pypi page

latest pkg is
scapy-2.2.0-dev.linux-x86_64.tar.gz (md5) //binary

easy_install script will choose the binary pkg to download, which failed anyway.

w/r is to download source manually.

wk is to inst basic package.

# yum install  rrdtool rrdtool-devel

1	# yum install rrdtool rrdtool-devel

and then re-run easy_install

note:
Anyway you can directly issue #yum install rrdtool-python.

Compile python3 on SLES 11 SP2

Install following RPMs before Steps:

libopenssl-devel-0.9.8j-0.50.1
zlib-devel-1.2.3-106.34

1 2	libopenssl-devel-0.9.8j-0.50.1 zlib-devel-1.2.3-106.34

Python3 source from: Python 3.3.5

Without zlib-devel, You cannot enable zlib module built-in, install this RPM and re-compile python3 src.
about bzip2, SLES doesnt provide extra bzip2-devel package, so just install bzip2 RPM is ok.

Without libopenssl-devel, you cannot fetch https URL via easy_install, it reports “unknown url type: https”
