TypeError: Cannot set property constructor of [object Object] which has only a getter

[albertopiva]

What were you trying to do?

I'm trying to compile the project

How did you attempt to do it?

Following the guidelines in MAINTAINERSHIP.md, I run the build command.

Note: I only cloned the repo, installed the node_modules and ran the build command.

What actually happened?

It crashes with the following error:

/pdf-lib/node_modules/ttypescript/lib/loadTypescript.js:11
        function __() { this.constructor = d; }
                                         ^

TypeError: Cannot set property constructor of [object Object] which has only a getter

What did you expect to happen?

I expect to see the expected output as described in MAINTAINERSHIP.md.

How can we reproduce the issue?

You only need to clone the project, install node_modules and run the build command.

Version

v1.17.1

What environment are you running pdf-lib in?

You need to upgrade ttypescript to version ^1.5.15. Re-install the packages and try to build again.

@brandnday thanks, seems working but I can notice that there're warnings at build time.
I also found another solution, using node v10 it works good.

EDIT: with your solution I have some build issue.

Bumping ttypescript to 1.5.15 worked for me. Running on Nodejs v22.13.1.
