node.js中的execSync不能正确运行shell命令
我试图在node.js中运行一个child_process.execSync shell命令，如下所示：
function test() { return new Promise(function(resolve, reject) { var execSync = require('child_process').execSync; var result = execSync('some executable I manually installed', { encoding: 'utf8', silent: true }); if (result.search('something') > -1) { resolve("ok"); } else if (result.search('something else') { resolve("nok"); } else { reject(Error("ERROR")); } }); } test().then(function(result) { console.log(result); }, function(err) { console.log(err); });
但是，我得到以下错误作为输出。
{ [Error: Command failed: my shell command] error: null, cmd: 'my shell command', file: '/bin/sh', args: [ '/bin/sh', '-c', 'my chell command' ], options: { silent: true, encoding: 'utf8', file: '/bin/sh', args: [ '/bin/sh', '-c', 'my shell command' ], envPairs: [ 'TERM_PROGRAM=Apple_Terminal', 'SHELL=/bin/bash', 'TERM=xterm-256color', 'TMPDIR=/var/folders/k5/qklhpvtj227_5vdnn2d_x6zr0000gn/T/', 'Apple_PubSub_Socket_Render=/private/tmp/com.apple.launchd.2zYqrvejoj/Render', 'TERM_PROGRAM_VERSION=361.1', 'OLDPWD=/usr/local/bin', 'TERM_SESSION_ID=8F8D0040-84DE-41F4-84E6-A9481A09CE73', 'USER=and', 'SSH_AUTH_SOCK=/private/tmp/com.apple.launchd.L5VoA4PiFl/Listeners', '__CF_USER_TEXT_ENCODING=0x1F5:0x0:0x0', 'PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin', 'PWD=/Users/and/Documents/', 'XPC_FLAGS=0x0', 'XPC_SERVICE_NAME=0', 'SHLVL=1', 'HOME=/Users/and', 'LOGNAME=and', 'LC_CTYPE=UTF-8', 'DISPLAY=/private/tmp/com.apple.launchd.rwoZybokZk/org.macosforge.xquartz:0', '_=/usr/local/bin/node' ], stdio: [ [Object], [Object], [Object] ] }, envPairs: [ 'TERM_PROGRAM=Apple_Terminal', 'SHELL=/bin/bash', 'TERM=xterm-256color', 'TMPDIR=/var/folders/k5/qklhpvtj227_5vdnn2d_x6zr0000gn/T/', 'Apple_PubSub_Socket_Render=/private/tmp/com.apple.launchd.2zYqrvejoj/Render', 'TERM_PROGRAM_VERSION=361.1', 'OLDPWD=/usr/local/bin', 'TERM_SESSION_ID=8F8D0040-84DE-41F4-84E6-A9481A09CE73', 'USER=and', 'SSH_AUTH_SOCK=/private/tmp/com.apple.launchd.L5VoA4PiFl/Listeners', '__CF_USER_TEXT_ENCODING=0x1F5:0x0:0x0', 'PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin', 'PWD=/Users/and/Documents/', 'XPC_FLAGS=0x0', 'XPC_SERVICE_NAME=0', 'SHLVL=1', 'HOME=/Users/and', 'LOGNAME=and', 'LC_CTYPE=UTF-8', 'DISPLAY=/private/tmp/com.apple.launchd.rwoZybokZk/org.macosforge.xquartz:0', '_=/usr/local/bin/node' ], stderr: '', stdout: '', pid: 16931, output: [ null, '', '' ], signal: null, status: 10 }
我认为它与/bin/sh （我是OS X的方式）有关，但我不知道如何解决这个问题。 我可以在terminal中运行shell命令，只是在execSync的节点中不起作用。 另外，当我尝试使用OS X附带的命令（如ls ）运行execSync时，它运行得非常好…
任何人都可以帮忙吗？ 谢谢！
如果最后的exec程序返回这个C代码的错误代码
#include <stdio.h> int main(void) { printf("hi"); return 1; }
重点是如果程序不返回0节点的child_process抛出错误
我的解决scheme
const proc = require('child_process'); // just add " || true" after your command var output = proc.execSync('command || true');
这对我来说很好:)
