Question

我正在构建一个基本上是Heroku克隆的应用程序。我不在试图使其跨平台的过程中。我遇到的麻烦之一是在linux上找到正确的节点路径。我的意思是，每当execSync（'哪个节点'）获取节点路径时，我的应用程序就会在运行时崩溃。我在该服务器应用程序的客户端make中使用了相同的命令，并且效果很好。

Wrapper running on port 2999
child_process.js:640
    throw err;
    ^

Error: Command failed: which node

interface PATHS {
    node: string;
    npm: string;
}
const PATHS: PATHS = {
    node: 'node',
    npm: 'npm'
};
if (process.platform == 'linux') {
    PATHS.node = execSync('which node')
        .toString()
        .slice(0, -1);
    PATHS.npm = execSync('which npm')
        .toString()
        .slice(0, -1);
} else if (process.platform == 'win32') {
    PATHS.node = execSync('where node')
        .toString()
        .slice(0, -1);
    PATHS.npm = execSync('where npm')
        .toString()
        .slice(0, -1);
}

错误：命令失败：哪个节点
