Playwrightの公式Dockerイメージでnpx playwrightを実行すると、こんなエラーが出る。

$ docker run -it --rm mcr.microsoft.com/playwright:v1.14.1 npx playwright@1.14.1
internal/modules/cjs/loader.js:892
  throw err;
  ^

をみても、とくにトラブルシューティングは~~マイクロソフトなので当然~~ない。

unsafe-perm=true にすればよい

エラーメッセージでググると

unsafe-permってフラグをtrueにせよと書いてある。ただ、npmであればこのパラメータがあるが、npxにはない。

どうすればいいか調べたところ、Qiitaに全く同じことを書いてる人が居た。

dockerコマンドなので、 -e npm_config_unsafe_perm=true を指定すれば良さそう。
