How to Install the Yaml Package for Python

How do I install the yaml package for Python?

You could try the search feature in pip,

$ pip search yaml

which looks for packages in PyPI with yaml in the short description. That reveals various packages, including PyYaml, yamltools, and PySyck, among others (Note that PySyck docs recommend using PyYaml, since syck is out of date). Now you know a specific package name, you can install it:

$ pip install pyyaml

If you want to install python yaml system-wide in linux, you can also use a package manager, like aptitude or yum:

$ sudo apt-get install python-yaml
$ sudo yum install python-yaml

How to install pyYAML on windows 10

1. Download the wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyyaml that suits your need (Python version, 32/64 bit).

2. $ pip3 install PyYAML-3.11-cp35-none-win32.whl

How to install packages from yaml file in Conda

You want the conda-env command instead, specifically

conda env update -n my_env --file ENV.yaml

Read the conda env update --help for details.

If you wish to install this in the base env, then you would use

conda env update -n base --file ENV.yaml

Note that the base env isn't technically "global", but rather just the default env as well as where the conda Python package lives. All envs are isolated unless you are either using the --stack flag during activation to override the isolation or have - contra recommended practice - manually manipulated PATH to include an env.

Why isn't yaml package getting installed in conda env?

As @Tzane already mentioned yaml is called pyyaml.

use,

conda install -c anaconda pyyaml

To download pyyaml.

How do I install the yaml package for my PyCharm Python project?

I think you're looking for pyyaml

https://pypi.org/project/PyYAML/

No module named yaml (brew broke my python, again)

There are two packages with somewhat unfortunate naming in the Python Package Index.

• pip install pyyaml lets you import yaml. This package enables Python to parse YAML files.
• pip install pyaml lets you import pyaml. This package allows pretty-printing of YAML files from Python, among other things. It requires pyyaml to be installed.

So the way forward for you is:

1. Install pyyaml, preferably using pip
2. Install pyaml
3. Profit

Step 0 would be to run everything from a virtual environment to prevent homebrew from messing with your Python ever again. This option also lets you run multiple versions of Python, not just the one required by homebrew.

Installing python2 pyyaml

Just do a curl for the following to install pip for python2:

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py

Then run
sudo python2 get-pip.py

You can then use the command pip2 --version tp check if pip is installed and for the correct version of python.
