NODE_OPTIONS=options...


以空格分隔的命令行选项列表 options... 在命令行选项之前被解释,因此命令行选项将在 options... 中的任何内容之后覆盖或复合。如果使用了环境中不允许的选项,例如 -p 或脚本文件。

如果选项值包含空格,则可以使用双引号转义:

NODE_OPTIONS='--require "./my path/file.js"'

作为命令行选项传入的单例标志将覆盖传给 NODE_OPTIONS 的相同标志:

# 检查器将在端口 5555 上可用
NODE_OPTIONS='--inspect=localhost:4444' node --inspect=localhost:5555

可以多次传入的标志将被视为首先传入其 NODE_OPTIONS 实例,然后是其命令行实例:

NODE_OPTIONS='--require "./a.js"' node --require "./b.js"
# 相当于:
node --require "./a.js" --require "./b.js"

A space-separated list of command-line options. options... are interpreted before command-line options, so command-line options will override or compound after anything in options.... Node.js will exit with an error if an option that is not allowed in the environment is used, such as -p or a script file.

If an option value contains a space, it can be escaped using double quotes:

NODE_OPTIONS='--require "./my path/file.js"'

A singleton flag passed as a command-line option will override the same flag passed into NODE_OPTIONS:

# The inspector will be available on port 5555
NODE_OPTIONS='--inspect=localhost:4444' node --inspect=localhost:5555

A flag that can be passed multiple times will be treated as if its NODE_OPTIONS instances were passed first, and then its command-line instances afterwards:

NODE_OPTIONS='--require "./a.js"' node --require "./b.js"
# is equivalent to:
node --require "./a.js" --require "./b.js"
