1.  Anaconda is a toolkit integrated management tool. It is very convenient to download Python toolkit

conda install package_ name

However, sometimes when a toolkit (such as xmltodict) is installed, if the package cannot be found in the current channels, you will be prompted:

conda install pydot Fetching package metadata ……. Solving package specifications: . PackageNotFoundError: Package not found: ” Package missing in current win-64 channels: – xmltodictYou can search for packages on anaconda.org with anaconda search -t conda xmltodict

Then enter Anaconda search – t CONDA xmltodict search result according to the prompt:

Now choose an appropriate version to install. For example, I choose this:

conda-forge/xmltodict | 0.10.2 | conda | linux-64, win-32, win-64, osx-64

Then execute the following command to install:

conda install -c https://conda.anaconda.org/conda-forge xmltodict
