How to solve the error when installing pear php5.3.1 in Windows

Phar "C: \ PHP \ pear \ go-pear.phar" doesNotHave a signature

PHP warning: require_once(Phar: /// go-pear.phar/index. php): Failed to open stream: phar error: Invalid URL or non-existent phar "phar: // go-pear.phar/index. php"InC: \ PHP \ pear \ go-pear.phar on line1236

But the command line method in php.exe can be smoothly installed (see http://blog.pear.php.net/2009/07/01/php-53-windows-and-pear ):

Open a command line window, switch the directory to the PHP Directory (my directory is "C: \ PHP"), and enter PHP-D phar. require_hash = 0 pear/go-pear.phar to enter the installation process.

The system will be installed locally or locally. Enter local and confirm with yes.

Next we will ask about the path. There are many options here. If you need to change some directories, enter the corresponding number. By default, press enter to continue.

Start installation. There may be some warnings in the middle, which can be ignored temporarily.

Next, you may receive a warning that the current PHP configuration file PHP. ini does not contain the pear directory. Then, ask if you want to change the configuration file and add it to the pear directory automatically. Enter y to confirm.

If you are careful, you can find that the path of the php. ini file has been changed.

The last part is included: first, the old pear version is found in the PHP root directory. BAT. in addition, the pear command is not included in the PATH environment variable. You need to add the PHP root directory to the path environment variable. Then, even if pear is successfully installed!

To add a path environment variable, follow these steps:

Open System Properties (you can press ALT and double-click "my computer" to open it), select the Advanced tab, and click "environment variable" below"

In the pop-up window, double-click "path" in the following system variables. In the pop-up editing box, add the PHP root directory (my directory is c: \ PHP) to the end of the variable value ), all the way to OK.

All the steps have been completed. For more information about pear, see its manual.
