ERROR: Invalid requirement: '=='
时间: 2024-06-01 17:11:06 浏览: 27
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.
