ReadStream: Cannot read property 'prototype' of undefined

[dolanmiu]

I am getting this issue:

#70

On these lines:

https://github.com/isaacs/node-graceful-fs/blob/master/graceful-fs.js#L165-L166

var fs$ReadStream = fs.ReadStream // ReadStream is undefined!
ReadStream.prototype = Object.create(fs$ReadStream.prototype)

But I am NOT on Meteor. I am using Angular2

I can confirm the issue.
Apparently fs contains only fs.FileReadStream (and fs.FileWriteStream) which may (?) be meant.

I have the same issue with a clean project that i created with create-react-app.
As i use chokidar in the App component i get this error on yarn start.

Hi all,
i have fixed my issue.
The problem was, that i have created an electron app in that i used react.
If you want to use chokidar in this constelation, you must import ist with the following code:
const chokidar = window.require('chokidar');

Maybe anyone has the same constelation and problem.

i have fixed my issue.

npm i chalk@2.0.1

it work fine.

i think it would help some one!

[medkhelifi]

I have the same problem;
React + Webpack 2
In webpack config, I added
node: { fs: 'empty' }
But the issue still remains.

[sjbwylbs]

@medkhelifi did't you try replace your chalk version to 2.0.1？

[gemma-ferreras]

I am having the same issue. Any updates? I used create-react-app and ejected it.

[dmftuva]

with FS you are trying to get file from clients computer? fs must be used on back ) no webpack

Dear Isaacs,
Could you close issues #121 and this after fixing this bug.
I tried to rewrite two last lines in your code in #121 by the pattern in my local node_modules and solved this problem in React app.
But I finded this precription for a long time, because no one issues not closed.

Best regards, Anela.

[spirosbax]

Here is how I fixed it:

• replace fs.ReadStream with fs.createReadStream in line 165,
• replace fs.WriteStream with fs.createWriteStream in line 169,

this works because in the docs there are create methods for creating streams.

Issue not fully resolved on my end after applying @spirosbax's fix manually. See: #135 (comment)

[DevCubeHD]

@rekmarks yeah, just think about when using git... nobody would ever include the node_modues folder

[coreyfarrell]

This issue should be resolved by latest graceful-fs. Please let us know if you continue to have problems after updating.
