pycrypto>=2.6
"""

df = parse(content, file_type=filetypes.requirements_txt)

print(df.json())

  "sha": null,
  "dependencies": [
    {
      "name": "South",

Python 2.7

This tool requires latest Python patch versions starting with version 3.5. We did support Python 2.7 in the past but, as for other Python 3.x minor versions, it reached its End-Of-Life and as such we are not able to support it anymore.

We understand you might still have Python 2.7 projects running. At the same time, Safety itself has a commitment to encourage developers to keep their software up-to-date, and it would not make sense for us to work with officially unsupported Python versions, or even those that reached their end of life.

If you still need to use Safety with Python 2.7, please use version 0.4.1 of Dparse available at PyPi. Alternatively, you can run Safety from a Python 3 environment to check the requirements file for your Python 2.7 project.
