[BUG] Npx Installation Issue

[omerxhafique]

After installing flowise, following errors are thrown when: npx flowise start

› ModuleLoadError: [MODULE_NOT_FOUND] require failed to load › /opt/homebrew/lib/node_modules/flowise/dist/commands/start.js: Cannot find › module '@opentelemetry/exporter-trace-otlp-proto' › Require stack: › - /opt/homebrew/lib/node_modules/flowise/node_modules/flowise-components/d › ist/src/handler.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/flowise-components/d › ist/src/index.js › - /opt/homebrew/lib/node_modules/flowise/dist/utils/index.js › - /opt/homebrew/lib/node_modules/flowise/dist/index.js › - /opt/homebrew/lib/node_modules/flowise/dist/commands/start.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/modu › le-loader.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/conf › ig/plugin.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/conf › ig/config.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/conf › ig/index.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/comm › and.js › - /opt/homebrew/lib/node_modules/flowise/node_modules/@oclif/core/lib/inde › x.js › - /opt/homebrew/lib/node_modules/flowise/bin/run › Code: MODULE_NOT_FOUND

Same with mine!

[punu13]

Same here. Can we change the title of this issue to make it more relevant?

[aeaswar81]

im having the same issue

[HenryHengZJ]

Can you try install a specific version like npm install -g [email protected]

[punu13]

npm install -g [email protected] Specific version Works

However npx update -g flowise && npx flowise start Gives me the same error

[Raycdnuaa]

me too

[serhato]

Same same. This module is not there: @opentelemetry/exporter-trace-otlp-proto

[cyb3rfox]

+1 on that

[MoRkusReX]

npm install -g [email protected]

Worked. Thanks.

npm install -g [email protected] resolved this issue for me also, however the Custom MCP node is not available which is a shame.

When installing the latest version of npm or any specific version like 2.2.7 or 2.2.6, this error blocks the installation. npm error code ETARGET npm error notarget No matching version found for @ai-sdk/[email protected]. npm error notarget In most cases you or one of your dependencies are requesting npm error notarget a package version that doesn't exist.

This works for me finally:

npm install -g flowise @opentelemetry/exporter-trace-otlp-grpc @opentelemetry/exporter-trace-otlp-proto @opentelemetry/sdk-trace-node && npm install langchainhub && npx flowise start

[RafaelTaves]

worked for mim, thanks for the help

[phazei]

Same here, can't install it without specifying version.

This works for me finally:

npm install -g flowise @opentelemetry/exporter-trace-otlp-grpc @opentelemetry/exporter-trace-otlp-proto @opentelemetry/sdk-trace-node && npm install langchainhub && npx flowise start

this is work for me thanks

This works for me finally:

npm install -g flowise @opentelemetry/exporter-trace-otlp-grpc @opentelemetry/exporter-trace-otlp-proto @opentelemetry/sdk-trace-node && npm install langchainhub && npx flowise start

This enables me to run flowise, according the console messages:

2025-06-12 21:53:53 [INFO]: Starting Flowise... 2025-06-12 21:53:53 [INFO]: ⚡️ [server]: Flowise Server is listening at 3000 2025-06-12 21:53:53 [INFO]: 📦 [server]: Data Source is being initialized! 2025-06-12 21:53:55 [INFO]: 📦 [server]: Data Source has been initialized! 2025-06-12 21:54:04 [INFO]: ⬆️ POST /api/v1/auth/resolve

but I get an immediate /undefined in the browser when I try to access it. Any ideas? http://localhost:3000/undefined

The Chrome developer tools don't seem too useful but I do see the referer in the request header is coming from the login page:

referer http://localhost:3000/login

any ideas?
