[英]How to execute npm script using grunt-run?
I have a npm task in my package.json file as follows to execute jest testing: 我在package.json文件中有一个npm任务,如下所示执行jest测试:
"scripts": {
"test-jest": "jest",
"jest-coverage": "jest --coverage"
},
"jest": {
"testEnvironment": "jsdom"
},
I want to execute this task npm run test-jest
using grunt. 我想使用grunt执行此任务npm run test-jest
。 I installed grunt-run for the same and added the run task, but how do I invoke this npm task there? 我为此安装了grunt-run并添加了运行任务,但是如何在那里调用这个npm任务呢?
run: {
options: {
// Task-specific options go here.
},
your_target: {
cmd: 'node'
}
}
Configure your Gruntfile.js
similar to the example shown in the docs. 配置您的Gruntfile.js
类似于文档中显示的示例 。
cmd
to npm
. 将cmd
的值设置为npm
。 run
and test-jest
in the args
Array. 在args
数组中设置run
和test-jest
。 Gruntfile.js Gruntfile.js
module.exports = function (grunt) {
grunt.loadNpmTasks('grunt-run');
grunt.initConfig({
run: {
options: {
// ...
},
npm_test_jest: {
cmd: 'npm',
args: [
'run',
'test-jest',
'--silent'
]
}
}
});
grunt.registerTask('default', [ 'run:npm_test_jest' ]);
};
Running 运行
Running $ grunt
via your CLI using the configuration shown above will invoke the npm run test-jest
command. 使用上面显示的配置通过CLI运行$ grunt
将调用npm run test-jest
命令。
Note: Adding --silent
(or it's shorthand equivalent -s
) to the args
Array simply helps avoids the additional npm log to the console. 注意:将--silent
(或它的简写等效-s
)添加到args
数组只会有助于避免额外的npm日志到控制台。
EDIT: 编辑:
Cross Platform 跨平台
Using the grunt-run
solution shown above failed on Windows OS when running via cmd.exe
. 在通过cmd.exe
运行时,在Windows操作系统上使用上面显示的grunt-run
解决方案失败。 The following error was thrown: 抛出以下错误:
Error: spawn npm ENOENT Warning: non-zero exit code -4058 Use --force to continue.
For a cross-platform solution consider installing and utlizing grunt-shell to invoke the npm run test-jest
instead. 对于跨平台解决方案,请考虑安装和使用grunt-shell来调用npm run test-jest
。
npm i -D grunt-shell
Gruntfile.js Gruntfile.js
module.exports = function (grunt) {
require('load-grunt-tasks')(grunt); // <-- uses `load-grunt-tasks`
grunt.initConfig({
shell: {
npm_test_jest: {
command: 'npm run test-jest --silent',
}
}
});
grunt.registerTask('default', [ 'shell:npm_test_jest' ]);
};
Notes 笔记
grunt-shell
requires load-grunt-tasks for loading the Task instead of the typical grunt.loadNpmTasks(...)
, so you'll need to install that too: grunt-shell
需要load-grunt-tasks来加载Task而不是典型的grunt.loadNpmTasks(...)
,所以你也需要安装它: npm i -D load-grunt-tasks
grunt-shell
, namely version 1.3.0
, so I recommend installing an earlier version. 对于旧版本的Windows,我必须安装旧版本的grunt-shell
,即版本1.3.0
,所以我建议安装早期版本。 npm i -D grunt-shell@1.3.0
EDIT 2 编辑2
grunt-run
does seem to work on Windows if you use the exec
key instead of the cmd
and args
keys... 如果使用exec
键而不是cmd
和args
键, grunt-run
似乎在Windows上grunt-run
...
For cross platform purposes... I found it necessary to specify the command as a single string using the exec
key as per the documentation that reads: 出于跨平台的目的......我发现有必要使用exec
键将命令指定为单个字符串,其文档如下:
If you would like to specify your command as a single string, useful for specifying multiple commands in one task, use the exec: key 如果要将命令指定为单个字符串,对于在一个任务中指定多个命令很有用,请使用exec:key
Gruntfile.js Gruntfile.js
module.exports = function (grunt) {
grunt.loadNpmTasks('grunt-run');
grunt.initConfig({
run: {
options: {
// ...
},
npm_test_jest: {
exec: 'npm run test-jest --silent' // <-- use the exec key.
}
}
});
grunt.registerTask('default', [ 'run:npm_test_jest' ]);
};
