[Bug]: Internal compiler error TypeError: fetch failed.

[mcbeelen]

Describe the bug

On a laptop from work, behind a corporate firewall, which does SSL offloading, fetchPackageManifest fails due to Error: unable to get local issuer certificate
.. code: UNABLE_TO_GET_ISSUER_CERT_LOCALLY

On our machines NPM points to an internal NPM-registry and we run with npm config set strict-ssl false.

Direct outbound connections are blocked.

How do I configure tsp to ignore certifcate-errors?

Hhm yeah we might not be fetching the endpoint configured.
As a workaround use npm install or whatever other package manager you prefer directely.

Just to make sure I understand your scenario you are not using the public npm registry but some alternate one but also that endpoint is not https(or it is but you don't have a valid certificate so you want to ignore that?)

@timotheeguerin : Hi Timothee,

We have an internal repository manager and configure NPM to pull from there instead of from the internet.
Direct access to the internet is blocked by a firewall, which does SSL off-loading with it's own CA.
Running the tsp command fails due to not being able to fetch packages.

Running npm install fixed my problem, since to triggered a download through our repository manager.

It would be nice if tsp would pick up on the NPM-settings.
