Editor to share with you what to do when there is something wrong with the installation of Composer. I believe most people don't know much about it, so share this article for your reference. I hope you will get a lot after reading this article. Let's learn about it together.

Install Composer

Before you do that, check your php version and related extensions

1.php > = 5.6

Whether the 2.OpenSSL extension has been configured

The 3.Composer installation package and the certificate download address required by OpenSSL

4. When the download is complete, open the installer and follow the steps.

5. Select the path in the middle to select the php version of the php.exe file you want to use

6. If there is a problem with the installation and the download fails, just try it a few more times.

If your OpenSSL extension is not configured, the following error may occur:

Some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again:The openssl extension is missing, which means that secure HTTPS transfers are impossible. If possible you should enable it or recompile php with- with-openssl

Solution:

1. In the php installation directory, such as D:\ wamp\ bin\ php\ php5.6\, find the php.ini file in the directory and remove the comment at the beginning of the line extension=php_openssl.dll. Note: because the SSL connection requires authentication, you need to prepare the CA certificate (it is recommended that the certificate be saved to the relevant directory of php) before continuing with the following steps, which can be downloaded from https://curl.haxx.se/docs/caextract.html. You can also download it from step 3 above.

two. Modify the openssl.cafile in the php.ini file. Create a ssl folder in the php folder, put the certificate in it, modify the php.ini file, openssl.cafile= "D:\ phpStudy\ php\ ssl\ cacert.pem", finally restart the php environment, and you should be able to install it.
