composer安裝

composer安裝的步驟

首先去http://www.phpcomposer.com/ 點擊下載進入https://getcomposer.org/download/ 然后 點擊 Composer-Setup.exe然后下載一個window下的composer安裝軟件

地址為 https://getcomposer.org/Composer-Setup.exe

下載后 點擊安裝 然后會選擇php.ini版本 然后勾選 ，然后一路安裝下去 有個長時間等待下載安裝包，等待安裝完成后，如果報錯 就檢查 PHP擴展的OpenSSL 有沒有打開。

然后在cmd命令行中輸入 composer 發現報錯

C:\Users\Administrator>composer
PHP Fatal error:  Uncaught exception 'PharException' with message 'phar "C:\ProgramData\ComposerSetup\bin\comp
oser.phar" has a broken signature' in C:\ProgramData\ComposerSetup\bin\composer.phar:23
Stack trace:
#0 C:\ProgramData\ComposerSetup\bin\composer.phar(23): Phar::mapPhar('composer.phar')
#1 {main}
  thrown in C:\ProgramData\ComposerSetup\bin\composer.phar on line 23

Fatal error: Uncaught exception 'PharException' with message 'phar "C:\ProgramData\ComposerSetup\bin\composer.

PharException: phar "C:\ProgramData\ComposerSetup\bin\composer.phar" has a broken signature in C:\ProgramData\
ComposerSetup\bin\composer.phar on line 23

Call Stack:
    0.0015     328520   1. {main}() C:\ProgramData\ComposerSetup\bin\composer.phar:0
    0.0015     328608   2. Phar::mapPhar() C:\ProgramData\ComposerSetup\bin\composer.phar:23

然后在網上找到了解決方案是替換覆蓋C:\ProgramData\ComposerSetup\bin下的composer.phar包 下載地址為 https://getcomposer.org/download/1.0.0-alpha8/composer.phar 然后下載好了直接覆蓋掉C:\ProgramData\ComposerSetup\bin\composer.phar即可

然后再次輸入composer

即得到
