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

Question

We are currently running into an issue where runnning bower update --allow-root via Symfony's Process component which results in an error or;

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

Running git or bower via the component retrieves expected response.

It seems as if bower/node cant find the git path. Running the follwoing via Symphony Process

echo $PATH

results in

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

inside /usr/bin is;

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

Running which git via Symfony Process returns /usr/bin/git

Running which bower via Symfony Process returns /usr/bin/bower

Running which node via Symfony Process returns /usr/bin/node

has anyone else ran into this problem or could suggest more tests to debug.

regards

EDIT

Ive debugged it back to /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;
}

EDIT 2

tracked it down to a node module which ;

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

which the line process.env.PATH is returning undefined .

Answer 1

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

process.env.PATH was returning undefined from the which node module;

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

Adding the PATH prefix to the command fixed this issue.

Being more specific to my issue, Symfony's Process class takes a third parameter for environment variables;

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