Solution:

Check whether the system environment is automatically configured. If not, please add the Path variable: C:\ProgramData\ComposerSetup\bin

Open cmd and enter composer - v. If the following is displayed, the installation is successful and can be accessed globally.

Switch to any directory and test composer -v again. The installation is successful as shown below.

Problem Description 2: Manual installation through the installation command failed, as shown below:

##Solution:

The error prompts that there is no Composer that supports PHP5.5.12. Update PHP version 5.6 and above.

Reinstall through the command. Before installation, please cd to the directory you want to install. Directory (can be created and specified by yourself), for example:

C:\Users\username>cd D: Switch to D drive

C:\Users\username>cd D:\Composer Switch to Composer folder (the installation directory you created)

D:\Composer>php -r "readfile('https://getcomposer.org/installer');" | php execute the installation command from this step The beginning and subsequent steps are the same as the tutorials in the official documentation, please refer to them by yourself to complete the subsequent operations.

The file path after the installation is completed. At this time, the composer -v command can only be executed in this directory, that is, it can only be accessed locally.

If you want global access, you need to configure the system environment variables yourself and add the Path variable: D:\Composer (please modify it according to your own installation directory)
