Download the corresponding version directly .whl file , And then run pip install xxx.whl Installation . This method is to bypass the compilation step , So don't rely on c++ Environment , But I don't really recommend this solution , Because I have to find it every time wel file , This is still a little troublesome , So in order to be lazy , After all, laziness is the primary productive force , It is still suggested to find out the environmental dependence , Install well , Subsequent packages are required directly pip Just install it .
According to the output information , We can download and install "Microsoft C++ Build Tools" This tool , To install this environment , Install one directly visual Studio A dozen G It can be , He will automatically install all the necessary packages for you , It's just too big , Many unnecessary packages are also installed .
