The last pycrypto instruction is missing the package and needs to be installed

Method 1: choose according to the situation. This method is not very recommended. Otherwise, you have to download a file to install every time you can’t run into it

1. Download pycrypto-2.6.1-cp36-cp36m-win_ Amd64.whl file (the file is currently backed up in your own system)

Copy the file to the local Python installation package e:// soft/Python 3.6_ Then open the CMD window in the scripts directory and run the

pip install pycryptosat‑0.2.0‑cp36‑cp36m‑win_amd64.whl

2. Access to other plug-ins https://www.lfd.uci.edu/~gohlke/pythonlibs/ Search inside to find the version, install the same way

Download Microsoft Visual C + + 14.0

Choose the default way to install, the computer does not need to restart, directly PIP install the required plug-ins on the line
