Pip Error: Microsoft Visual C 14.0 Required

Encountering the error message "Microsoft Visual C 14.0 is required" while attempting to install steem using pip can be frustrating. To address this issue, let's delve into the cause and the necessary steps to resolve it.

The error message indicates that your Python installation requires Microsoft Visual C 14.0 to complete the pycrypto installation. Pycrypto, a dependency for steem, relies on a compiler for building its C extensions.

Solution

To install Microsoft Visual C 14.0, follow these steps:

1. Navigate to https://wiki.python.org/moin/WindowsCompilers#Microsoft_Visual_C.2B-.2B-_14.2_standalone:_Build_Tools_for_Visual_Studio_2019_.28x86.2C_x64.2C_ARM.2C_ARM64.29
2. Click on the link to "Visual C 2015 Build Tools."
3. Download and install the build tools.

Alternate Solution

If you prefer not to install a compiler, you can consider the following alternate approach:

1. Download a binary version of pycrypto that is compatible with Python 3.x.
2. Ensure that the downloaded binary is trusted and has not been compromised.
3. Place the binary in a location where Python can find it.

Next Steps

Once Visual C 14.0 is installed or the binary has been placed, re-run the original command to install steem:

pip install -U steem

If you encounter any further issues, consider consulting the official pip documentation for additional troubleshooting steps.
