Invalid string length

[jycouet]

Hello,

I'm using yarn v1.3.2 and I have a bug.

What is the current behavior?
I'm running yarn from js like this:

    ({ stdout, stderr } = await exec('yarn install --ignore-scripts  --ignore-engines', {
      cwd: tmpDir,
      shell: true,
      env: { NODE_ENV: 'dev', PATH: process.env.PATH },
    }));
    logger.debug(`yarn stdout:\n${stdout}`);
    logger.debug(`yarn stderr:\n${stderr}`);

And I often get: "stderr": "error An unexpected error occurred: \"Invalid string length\".\n"

Here is my trace:

Trace: 
  RangeError: Invalid string length

You you can see the package.json that I have (nothing really special?):

I don't get what could be the issue; Could you help me please?

Please mention your node.js, yarn and operating system version.
node: 8.7.0

Tried but couldn't reproduce it.

[anderszhang]

yes , i have same problem .
yarn v1.3.2
node 8.9.1
platform mac os 10. 13.1

[bestander]

Could be Node.js specific

[rhendric]

I think that's the part of yarn that handles yarn.lock; is it possible that's corrupted? Can you rename it (for further testing) and try running yarn again?

[jycouet]

Hi,
I just found my issue thx to @rhendric
Yes my file was corrupted... I was copying only half of the file!!!

I owe you a 🍺

Hi,
I'm running yarn on windows. Installed with the MSI installer. current version is 1.4.0-20180115.1714, this problem occurs in yarn 1.3.2 also. It's reacting really slow to any command and then thinks for a while when printing out: (Can be good to mention that i'm behind a corporate proxy. Not sure how much this matters).

I actually get the same result if I do "yarn init"

yarn run v1.4.0-20180115.1714 error An unexpected error occurred: "Invalid string length". info If you think this is a bug, please open a bug report with the information provided in "C:\\\\\\yarn-error.log". info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
Currently running Node v8.9.1.

Not sure what to try?

Solved

1. Ran yarn --verbose and checked every file that was listed to see if there was an error in them.
2. Found oout that one .npmrc file had a wrong proxy definition. using "=" instead of " " (space).
3. It is now working.

Should be:
proxy http://proxy.xx.se:98
https-proxy http://proxy.xx.se:98

Was:
proxy=http://proxy.xx.se:98
https-proxy=http://proxy.xx.se:98

Bye 👍
