[tanay-nagarsheth]

@rohit270699 I am facing Type Error : TS2307

[supriyodey]

me too facing the same issue

[yk-x-25]

Guys, you need to start server. run python datafeed/server3.py

[Sarthakkathuria]

@tanay-nagarsheth this package has been moved to @finos/perspective
try npm i @finos/perspective
and update it in src/Graph.tsx and package.json

[Ayaanmoh]

@Sarthakkathuria Making those changes haven't fixed the problem. It says cannot find module @finos/perspective

[Ayaanmoh]

@TheYk98 Started the server. It runs without any issues. Then when we run npm start, we get the error.

[yk-x-25]

@Ayaanmoh try deleting node_modules and replace with the node_modules folder(link in the doc) in the path. If you've tried that too, I'm not sure what's wrong

[Ayaanmoh]

I have tried replacing. after that npm start fails to start the server. I will try shifting to Windows for this task.

[Sarthakkathuria]

@Ayaanmoh check this
npm i @finos/perspective
https://www.npmjs.com/package/@finos/perspective

[Ayaanmoh]

@Sarthakkathuria tried to install finos as well. But it gave me the same error. i performed this on a virtual mac machine and it worked.
Steps:
npm install
npm i @finos/perspective
npm start

[harsh725]

Even i am getting TS2307
anyone got the solution ?
i tried everything del node_modules , doing it again ,then i made changes in graph file
'@finos/perspective' insted of jpmorgan
still getting that error.

[SulthanNK]

I am also facing this issue, anyone got the solution?

[chandrikadeb7]

Change Line 2 of src/Graph.tsx to:
import { Table } from '@finos/perspective';
For Mac environment.

[SulthanNK]

what is the error, sir, please help, this error has been breaking my head since a long time now

I also faced this issue yesterday, but I noticed that the actual problem that I have is a different version of node and npm. so, I downgrade it to the version to what mentioned in the setup pdf document(for windows)

[shivansh49]

@Sarthakkathuria did you got the solution i am also facing same issue?please help

[shivansh49]

@tanay-nagarsheth did you got solution please help i am also facing same issue

[vishwakarmanikhil]

for this error

1. if you are using npm v11.0.0 then you will not face this error
   check your npm version first by command :
   node -v

2.if you have greater version than v11.0.0 then
just go to the your project directory and just type the command:
npm i @finos/perspective

this will install the required files in your project directory
and then goto your graph.tsx file and replace

import { Table } from '@jpmorganchase/perspective';

with this below code

import { Table } from '@finos/perspective';

[amarnathz]

what I did to solve this issue is

1. install nvm(node version manager) https://github.com/coreybutler/nvm-windows/releases
   filename : nvm-setup.zip
   2.open terminal and run nvm -v to check whether install or not
   3.then, install >>>>> nvm install v11.0.0 //it store node v11 in temp folder
2. use that version by, nvm use 11.0.0
   5, then npm install and npm start

[amarnathz]

after all, did it show like this

[prashundey]

If you're trying to download via @finos/perspective to solve the issues, you might just run into more issues with the dependencies. Usually, the problems for npm install regarding this setup is one or all of the three below:

If you're in a mac environment experiencing this problem, there could be a few areas of conflict

1. Make sure you are using the correct nvm version
   $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
   $ nvm install v11.0.0
   $ nvm use v11.0.0

2. Npm is probably not mapped to python locally, so it cannot find an executable python during 'npm install'. This is stated in the debugging portion of the guide. For most installations python is located at /usr/bin/python
   $ npm config set /usr/bin/python

3. Npm install fails on node-gyp rebuild with "gyp: No Xcode or CLT version". You can simply remove the older version and reinstall
   (npm install fails on node-gyp rebuild with "gyp: No Xcode or CLT version detected!" schnerd/d3-scale-cluster#7)
   $ sudo rm -rf /Library/Developer/CommandLineTools
   $ xcode-select --install

hey, preyal this side, have you resolved the issue?
i am still facing the same issue.

[vishwakarmanikhil]

@preyalameta02 In the error it is showing that react keyword is not recognized by the compiler. That's why it's giving this error. you have to import react module. If you have imported then check if modules are correctly installed or not.

Deleted the package-lock.json file & then run

npm install

still face the issue than try to debug with below page

ok cool

[noviicee]

So I encountered a similar problem and it was due to npm install.
I am on ubuntu, and there is usually python 2.7 installed on many linux versions including ubuntu.
However my machine did not have python pre-installed and therefore running npm install produced errors because it could not map to the python packages, and ultimately gave the same error as mentioned above on running npm start. Notice if you are getting a similar error like so.

Just check if python is present in your machine or not by exceuting python --version on your terminal. If python is not present, then better to install it using sudo apt-get install python. After that if you again execute python --version` on your terminal, you'll see that python 2.x will be present.

One thing which I tried to do here is to install npm in a different python version by using npm install --python=python3.8.10 , because python3 is present on my machine but it did not work.

Everything worked fine after I did this. If it still does not solve the problem then the above approaches might be of help :)

The first step is to run the server file,
second to check the correct nvm versions while using (as mentioned in the guide)
third, to execute npm install without any errors.

[akalam1]

whoever still stuck and couldnt find any solution, try this, it worked for me, hope it works for u...
cd datafeed

once you are there do:
npm install
once u do that, do the following:
npm install --ignore-scripts

Finally Run the main script:

npm start

This should work....

mainly for python3++

[PreciousJac0b]

@akalam1 I am facing a similar issue with task 3. After installing the finos and all.I am facing an error with the DataManipulator imported. Did you encounter this?

[loannejee]

What worked for me is entering this all at once:
npm install react react-dom @finos/perspective --save
Then:
Go to the Graph.tsx file and replace
import { Table } from '@jpmorganchase/perspective';
with
import { Table } from '@finos/perspective';

[PreciousJac0b]

Great!
What worked for me was running npm install without nvm, I used the nodejs route and it worked!

This is the exact problem I experienced. Install npm via the node js route not nvm. And do not replace @jpmorganchase perspective with @finos for task 3. Goodluck!
