Gradle"...在Mac上发生了启动过程'命令'npm''"

Question

我安装了IntelliJ Idea的MacOS.我正在使用Gradle(gradle-2.4)来构建项目.我在Mac上安装了NodeJS和NPM,可从shell获得.

MacBook:~ user$ node -v
v4.2.2
MacBook:~ user$ npm -v
2.14.7

运行使用NODE/NPM的Gradle任务时,它会因以下错误而失败(在当前示例中为NPM).

* What went wrong:
Execution failed for task ':module:task'.
> A problem occurred starting process 'command 'npm''

Gradle的错误堆栈跟踪如下.

Exception is:

所以看起来Gradle试图在项目绝对目录中找到NPM并且不使用Mac PATH环境变量.任何人都知道如何避免/解决这个问题？我不能使用NODE/NPM的绝对路径,因为团队共享并使用不同的操作系统(Linux,MacOS).有任何想法吗？:)

Answer 1

我通过运行来停止gradle守护进程

$ ./gradlew --stop

重新运行gradle命令并修复它.

Answer 2

我有一个类似的问题,在我的情况下,问题是,当我从IntelliJ运行它时,Gradle无法访问路径以找出node/npm的位置.我正在使用gradle-gulp-plugin并启用节点的自动下载解决了这个问题.

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath('be.filipblondeel.gradle:gradle-gulp-plugin:0.1')
    }
}
node {
    // Version of node to use.
    version = '0.12.0'

    // Enabled the automatic download.
    download = true
}

Answer 3

我遇到了同样的问题，并通过运行以下命令解决了它：

gradle --stop

Answer 4

可能对某人有用：

就我而言，问题是我运行了Android Studio。必须先退出，然后一切正常。

Answer 5

我在尝试运行 Gradle 任务时遇到了同样的问题，这些任务从 Intellij 中的 Gradle 插件执行命令（例如 node 和 npm）。您可以从堆栈跟踪中看到 Gradle 插件正在尝试执行外部系统命令，并且出现如下错误：

WARN - nal.AbstractExternalSystemTask - error=2, No such file or directory 
com.intellij.openapi.externalSystem.model.ExternalSystemException: error=2, No such file or directory
at org.jetbrains.plugins.gradle.service.project.GradleExecutionHelper.execute(GradleExecutionHelper.java:228)

如果从路径中删除可执行文件（即节点、npm），您可以从命令行重现此错误，这告诉我有关插件的某些内容不遵循环境路径。

我的 Gradle 插件正在使用项目 gradlew（gradle 包装器版本 2.3），因此我尝试将该插件指向我系统上更新的 Gradle 安装（版本 2.10）并且它有效。

然后，我通过为我的项目重新生成 gradle 包装器，然后将 IntelliJ Gradle 插件设置为指向我的包装器来解决我的问题。

我不知道原来的问题是什么。
