Prettier-atom: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script

[mrmurphy]

I just installed [email protected] (which supports typescript formatting) in my local project, added .ts onto list of files that prettier should run on, and saved a typescript file. I got the following output:

EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self'".

I'm currently trying to get a hotfix done, but the problem is that 1.4 introduces the use of eval which is against Atom's Content Security Policy (CSP). There is a loophole for this, but it isn't working correctly in this case. I'm still searching for a solution.

[margic]

Is that 1.4 of prettier itself. Is there a known good version to work with while you work on the fix?

[margic]

Answering my own question dropping prettier to "prettier": "1.31.1", works for now with prettier-atom 0.31.1

[robwise]

Looks like they are going to release a 1.4.1 that will address this, until then, please use margic's solution, the version number is 1.3.1.

[robwise]

Okay 1.4.1 was just released, and I've verified that this solves the problem!
