[英]How to run multiple PowerShell commands with package.json scripts
I have the following script definition "debug-windows" in my package.json
:我的
package.json
中有以下脚本定义“调试窗口”:
{
"scripts": {
"debug-windows": "$env:NODE_ENV=\"dev\"; node src/dequeue.js"
}
}
Which I run using npm run debug-windows
and I get the error:我使用
npm run debug-windows
并收到错误消息:
> servicebus-timeout@1.0.0 debug-windows C:\myapp
> $env:NODE_ENV="dev"; node src/dequeue.js
The filename, directory name, or volume label syntax is incorrect.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! servicebus-timeout@1.0.0 debug-windows-test: `$env:NODE_ENV="dev"; node src/dequeue.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the servicebus-timeout@1.0.0 debug-windows-test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\<USERNAME>\AppData\Roaming\npm-cache\_logs\2020-04-27T16_29_32_585Z-debug.log
If I run the same command directly on PowerShell it succeeds:如果我直接在 PowerShell 上运行相同的命令,它会成功:
PS C:\myapp> $env:NODE_ENV="dev"; node src/dequeue.js

I spent some time checking the npm docs and found out the problem.我花了一些时间检查 npm 文档并发现了问题。
npm-run-script
runs CMD on Windows, and not PowerShell. npm-run-script
在 Windows 上运行 CMD,而不是 PowerShell。
The solution was to separate the commands using &
and the appropriate set
to define session variables:解决方案是使用
&
和适当的set
分隔命令以定义 session 变量:
"debug-windows": "set NODE_ENV=dev & node src/dequeue.js"
I have no need for npm to use PowerShell, it's just that I thought it was doing so.我没有必要让npm使用PowerShell,只是我以为是这样做的。
If one wants to run PowerShell for other reasons, check this thread which has a lot of options.如果出于其他原因想要运行 PowerShell,请查看这个有很多选项的线程。
Documentation on npm-run-script :关于npm-run-script 的文档:
The actual shell your script is run within is platform dependent.
您的脚本在其中运行的实际 shell 取决于平台。 By default, on Unix-like systems it is the /bin/sh command, on Windows it is the cmd.exe.
默认情况下,在类 Unix 系统上是 /bin/sh 命令,在 Windows 上是 cmd.exe。 The actual shell referred to by /bin/sh also depends on the system.
/bin/sh 所指的实际 shell 也取决于系统。 As of npm@5.1.0 you can customize the shell with the script-shell configuration.
从 npm@5.1.0 开始,您可以使用 script-shell 配置自定义 shell。
