Error message "error Command failed with exit code 1" is missing vital information -- what command failed?

Bug description

I am helping to debug a CI build which is failing with the following output:

error Command failed with exit code 1
error Command failed with exit code 1

It prints the error message twice. We can't tell which command failed. The command is missing from the error message. It would be nice if the error message included the command so that we could see what's happening and fix it.

Command

yarn run webpack:verify

What is the current behavior?

Yarn prints the error message

error Command failed with exit code 1

What is the expected behavior?

It would be nice to have completed information, e.g. (made up example):

error Command "/bin/rm /tmp/nosuchfile" failed with exit code 1

Or, even better, show any stdout/stderr from the command:

error Command "/bin/rm /tmp/nosuchfile" failed with exit code 1: "rm: /tmp/nosuchfile: No such file or directory"

Steps to Reproduce

Environment

• Node Version: v8.16.2
• Yarn v1 Version: 1.19.2
• OS and version: Amazon Linux 2

I found this error message here:

yarn/__tests__/integration.js

Line 451 in a4708b2

expect(stderr).toEqual('error Command failed with exit code 1.');

I am not sure how it relates to the section where the error repot is made:

yarn/src/util/execute-lifecycle-script.js

Line 363 in a3b1294

: reporter.lang('commandFailedWithCode', err.EXIT_CODE),

我在这里发现了这个错误信息：

yarn/__tests__/integration.js

Line 451 in a4708b2

expect(stderr).toEqual('error Command failed with exit code 1.');

我不确定它与生成错误报告的部分有何关系：

yarn/src/util/execute-lifecycle-script.js

Line 363 in a3b1294

: reporter.lang('commandFailedWithCode', err.EXIT_CODE),

Hi, I am in the same trouble just like you, have you resolve this problem?

We did, but I don't remember how... Sorry!
