pypiece 0.1.3

Wrapper around pip for flakey connections.

Wrapper around pip for use with flaky connections.

Basic idea behind it is that default behaviour of pip to download all packages at one and compile them can get pretty frustrating in situations, where single error in downloading or installing a package can result in repeating whole process all over again.

pypiece tries to get around that by trying to download and install each package separately, by calling pip for each line of requirements.txt. In the end it outputs list of successfully installed packages and ones that failed.

Usage

<pre> pypiece < requirements file > < – PIP options > </pre>

Available options:

• –pip - specify pip binary to use

• –retries <N> - try to reinstall failing package _N_ times (default: 3).

• –venv <name> - install to virtualenvwrapper created virtual environment _name_.

pip arguments

If – is found in command line, then all arguments after it will be passed unchanged to pip executable on every call.

For example, <pre>pypiece requirements.txt – -i https://my.pypi.repo</pre>

is equivalent to <pre>pip install -r requirements.txt -i https://my.pypi.repo</pre>

Examples

<pre>pypiece requirements.txt</pre> We will try to install every package found in _requirements.txt_ one by one, retrying 3 times if necessary.

<pre>pypiece –venv test requirements.txt</pre> pypiece will try to find virtualenv _test_ in directory specified by _WORKON_HOME_ variable. If successful, it will use pip from this virtualenv.

<pre>pypiece –pip my_env/bin/pip requirements.txt</pre> pypiece will try to use provided pip binary for installation purposes.
