【问题描述】:
我正在尝试为我的 nodeJS 应用程序编写一个停止命令,该命令 greps 并杀死它,到目前为止我有:
{
...
"scripts": {
"start": "node src/main/webapp/index.js",
"stop": "kill \"$(ps ux | grep node | grep -Eo '^\\s+[0-9]+' | tr -d '[[:space:]]')\""
}
...
}
如果我运行 ps ux 我会得到
PID PPID PGID WINPID TTY UID STIME COMMAND
12228 8428 12228 12960 cons0 197608 22:02:12 /usr/bin/ps
4840 1 4840 4840 cons0 197608 22:01:46 /usr/bin/bash
13484 12292 12292 8024 cons0 197608 22:02:07 /c/Program Files/nodejs/node
如果我运行echo "$(ps ux | grep node | grep -Eo '^\s+[0-9]+' | tr -d '[[:space:]]')",那么我会得到输出13484,所以我知道该位有效。但是,当我运行 npm stop 时出现错误:
npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "stop"
npm ERR! node v0.12.4

npm ERR! code ELIFECYCLE

npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the app@1.0.0 stop script 'kill "$(ps ux | grep node | grep -Eo '^\s+[0-9]+' | tr -d '[[:space:]]')"'.
npm ERR! This is most likely a problem with the app package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR! kill "$(ps ux | grep node | grep -Eo '^\s+[0-9]+' | tr -d '[[:space:]]')"
npm ERR! You can get their info via:
npm ERR! npm owner ls app
npm ERR! There is likely additional logging output above.
为什么会这样?有没有更简单的方法来做到这一点?
