I have some statistical results wanted to export to PDF format, I search this website and seems using FPDF is a good choice. I am using Anaconda under windows 10 and in Anaconda Prompt I typed the codes as illustrated in Anaconda clouds: conda install -c foxbms fpdf But an error occurs, which says: UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment: Specifications: - fpdf -> python[version='>=3.6,<3.7.0a0'] Your python: python=3.7 If python is on the left-most side of the chain, that's the version you've asked for. When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Note that conda will not change your python version to a different minor version unless you explicitly specify that. The following specifications were found to be incompatible with each other: Package wincertstore conflicts for: fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> setuptools -> wincertstore[version='>=0.2'] python=3.7 -> pip -> setuptools -> wincertstore[version='>=0.2'] Package certifi conflicts for: python=3.7 -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26'] fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26|>=2017.4.17'] Package wheel conflicts for: fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> wheel python=3.7 -> pip -> wheel Package setuptools conflicts for: fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> setuptools python=3.7 -> pip -> setuptools Package pip conflicts for: fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip python=3.7 -> pip Package ca-certificates conflicts for: python=3.7 -> openssl[version='>=1.1.1a,<1.1.2a'] -> ca-certificates fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> requests -> urllib3[version='>=1.21.1,<1.24'] -> cryptography[version='>=1.3.4'] -> openssl[version='>=1.1.1a,<1.1.2a'] -> ca-certificates Package msgpack-python conflicts for: fpdf -> python[version='>=3.6,<3.7.0a0'] -> pip -> cachecontrol -> msgpack-python Is it because my 3.7.4 python version is higher than required 3.6? And if their is any solution to install FPDF? Thanks. And I appologize if this is a silly question. Continue reading...
