ed to update it by running "C:\ProgramData\ComposerSetup\bin\composer.phar self-

Problem 1
- Installation request for phalcon/incubator dev-master -> satisfiable by ph
alcon/incubator[dev-master].
- phalcon/incubator dev-master requires ext-phalcon >=2.0.4 -> the requested
PHP extension phalcon is missing from your system.
答案 0 :(得分：1)
最后一行应该给你一个线索：你还没有在你的系统上安装PhalconPHP，这是孵化器包所需要的。
另外，按照建议运行composer self-update。
