项目比较大，资源很多，在打包web-mobile的时候经常会报错

macOS 解决 too many open files 参考

内核的限制

整个操作系统可以打开的文件数受内核参数影响，可以通过以下命令查看

$ sysctl kern.maxfiles
$ sysctl kern.maxfilesperproc

在我电脑上输出如下

kern.maxfiles: 49152
kern.maxfilesperproc: 42576

好像已经很大了。

如果需要临时修改的话，运行如下命令

$ sudo sysctl -w kern.maxfiles=20480 # 或其他你选择的数字
$ sudo sysctl -w kern.maxfilesperproc=18000 # 或其他你选择的数字

永久修改，需要在 /etc/sysctl.conf 里加上类似的下述内容

kern.maxfiles=20480
kern.maxfilesperproc=18000

这个文件可能需要自行创建

launchd 对进程的限制

获取当前的限制：

$ launchctl limit maxfiles

输出类似这样：

    maxfiles    256            unlimited

其中前一个是软限制，后一个是硬件限制。

临时修改：

$ sudo launchctl limit maxfiles 65536 200000

系统范围内修改则需要在文件夹 /Library/LaunchDaemons 下创建一个 plist 文件 limit.maxfiles.plist ：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>65536</string>
      <string>200000</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>

修改文件权限

$ sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
$ sudo chmod 644 /Library/LaunchDaemons/limit.maxfiles.plist

载入新设定

$ sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist

shell 的限制

通过下述命令查看现有限制

$ ulimit -a

得到如下输出

...
-n: file descriptors                256
...

通过 ulimit -S -n 4096 来修改。如果需要保持修改，可以将这一句命令加入你的 .bash_profile 或 .zshrc 等。

windows也会出这个报错，有解决方案吗？
