Why Does Pip Installation of Steem Require Microsoft Visual C 14.0, and How Can I Fix It?

Pip Error: Understanding and Resolving "Microsoft Visual C 14.0 is required"

Issue:

When attempting to install steem using pip, users encounter the error: "Microsoft Visual C 14.0 is required." This error arises due to the dependency on pycrypto, which necessitates the Microsoft Visual C 14.0 compiler.

Solution:

To resolve this error and successfully install steem, follow these steps:

1. Install Microsoft Visual C 14.0:

   Visit the following link: http://landinghub.visualstudio.com/visual-cpp-build-tools and download "Visual C 2015 Build Tools." This will install Visual C 14.0 without requiring Visual Studio.

2. Re-run Pip Command:

   Once Visual C 14.0 is installed, re-run the pip command:

   pip install -U steem

Additional Notes:

1. Avoiding Third-Party Binaries:

   It is not recommended to download precompiled binary versions of pycrypto from third parties. To ensure compatibility and security, it is best to build it from the source.

2. Understanding Pip Install Options:

   The -U (upgrade) option upgrades all specified packages to their latest versions. If steem is not already installed, you can omit the -U option. To learn more about pip install options, run:

   pip help install
