ERROR: Invalid requirement: '–r'

It seems like the dash character you used is not recognized as a valid character. Please try using a regular dash (-) instead of an em dash (–) or an en dash (–) when specifying your requirements. For example, instead of using "pip install –r requirements.txt", use "pip install -r requirements.txt".

ERROR: Invalid requirement: '=='

This error message usually occurs when there is a syntax error in the requirement specifier in a Python package installation command. The '==' operator is commonly used in requirement specifiers to specify a specific version of a package.

To resolve this error, review the requirement specifier and ensure that it is written correctly. It should follow the format: package-name==version-number.

For example, to install version 2.2.0 of the requests package, the correct requirement specifier would be:

pip install requests==2.2.0

If the error persists, try updating pip to the latest version:

pip install --upgrade pip

If the problem still persists, try removing any whitespace or special characters from the requirement specifier.
