Bower-使用Symfony Process在PATH中未安装或未安装ENOGIT git

Question

当前，我们遇到了一个问题，即通过Symfony的Process组件运行bower update --allow-root会导致错误或；

bower jquery#* <3.0 * * * * * * * * ENOGIT git is not installed or not in the PATH

通过组件运行git或bower检索预期的响应。

看来Bower / Node无法找到git路径。 通过Symphony Process进行跟踪

echo $PATH

结果是

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

/usr/bin里面是;

lrwxrwxrwx 1 root   root          35 Feb 21 09:06 bower -> ../lib/node_modules/bower/bin/bower
lrwxrwxrwx 1 root   root          22 Jan 23 11:49 node -> /etc/alternatives/node
-rwxr-xr-x 1 root   root          25163808 Jan  6 00:12 nodejs
lrwxrwxrwx 1 root   root          38 Jan  6 00:11 npm -> ../lib/node_modules/npm/bin/npm-cli.js
-rwxr-xr-x 1 root   root          1862800 Mar 23  2016 git

通过Symfony Process运行which git返回/usr/bin/git

通过Symfony Process运行which bower返回/usr/bin/bower

通过Symfony Process运行which node将返回/usr/bin/node

有没有其他人遇到这个问题，或者可以建议更多测试进行调试。

我已经将其调试回/usr/lib/node_modules/bower/lib/util/createError.js

var which = require('which');
var hasGit;

// Check if git is installed
try {
    which.sync('git');
    hasGit = true;
} catch (ex) {
    hasGit = false;
}

跟踪它到一个节点模块which ;

https://github.com/npm/node-which/blob/master/which.js#L21

这行process.env.PATH返回undefined 。

Answer 1

export PATH=$PATH:/usr/bin; bower update

process.env.PATH从which节点模块返回undefined ；

https://github.com/npm/node-which/blob/master/which.js#L21

在命令中添加PATH前缀可解决此问题。

针对我的问题，Symfony的Process类采用了第三个参数作为环境变量。

$process = new Process( 'php composer.phar update', $path, [ 'PATH' => '/usr/bin', 'HOME' => '/home/forge' ] );
