wasm-pack test でエラー

November 29, 2021

WSL2 環境で wasm-pack test がエラーになる。

$ wasm-pack test --chrome --headless

libnss3.so がないとのことなので入れてみる。

$ sudo apt-get install libnss3

全然わからないが、ググったところ chromium が入ってないのかも？？

sudo apt-get update
sudo apt-get install  chromium-browser chromium-chromedriver

出力を紛失してしまったが以下のようなメッセージが出る・・・。

Please install it with: requires the chromium snap to be installed.

snap install chromium

言われるがまま、snap install chromiumを打つもダメ・・・。

https://github.com/microsoft/WSL/issues/5126#issuecomment-653715201

を参考に以下をインストール。

sudo daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target
exec sudo nsenter -t $(pidof systemd) -a su - $LOGNAME
snap version

sudo snap install chromium

これで行けるようになったっぽい。

今後テスト実行の前には、以下を叩く必要あり。

$ exec sudo nsenter -t $(pidof systemd) -a su - $LOGNAME
$ wasm-pack test --chrome --headless
