[英]Set environment variables grunt or grunt-exec
I'm trying to use grunt-exec to run a javascript test runner with a deployed link variable passed in. 我正在尝试使用grunt-exec来运行传入的已部署链接变量的javascript测试运行器。
I am trying to do so by setting an environment variable grunt.option('link')
using exec:setLink
. 我试图通过使用exec:setLink
设置环境变量grunt.option('link')
来exec:setLink
。 In my test_runner.js
I grab the variable with process.env.TEST_LINK
. 在我的test_runner.js
我使用process.env.TEST_LINK
获取变量。 Unfortunately, it appears that grunt-exec won't run bash commands such as export(?) 不幸的是,似乎grunt-exec不会运行bash命令,例如export(?)
Really, I don't care how the variable gets to my test_runner.js
so any other ideas would be welcome. 真的,我不关心变量如何到达我的test_runner.js
所以任何其他想法都会受到欢迎。
exec: {
// DOESN'T WORK: Sets env variable with link for selenium tests
setLink: {
cmd: function () {
return "export TEST_LINK=" + "'" + grunt.option('link') + "'";
}
},
// Integration tests, needs TEST_LINK
selenium: {
cmd: function () {
return "node test/runner/jasmine_runner.js";
}
}
With grunt-exec
, environment variables for the child process can be specified in the env
option : 使用grunt-exec
,可以在env
选项中指定子进程的环境变量:
exec: {
selenium: {
cmd: function () {
return "node test/runner/jasmine_runner.js";
},
options: {
env: {
'TEST_LINK': grunt.option('link')
}
}
}
}
One thing to bear in mind is that if only TEST_LINK
is specified in the env
option, that will be the only environment variable for the child process. 要记住的一件事是,如果在env
选项中只指定了TEST_LINK
,那么这将是子进程的唯一环境变量。 If you want the current process's environment variables to be passed, too, you can do something like this: 如果您希望传递当前进程的环境变量,也可以执行以下操作:
exec: {
selenium: {
cmd: function () {
return "node test/runner/jasmine_runner.js";
},
options: {
env: Object.assign({}, process.env, { 'TEST_LINK': grunt.option('link') })
}
}
}
I ended up just using node process.env['TEST_LINK'] = grunt.option('link');
我最后只使用了node process.env['TEST_LINK'] = grunt.option('link');
Then retrieved in my javascript with process.env['TEST_LINK'];
然后在我的javascript中使用process.env['TEST_LINK'];
检索process.env['TEST_LINK'];
