Docker上のyarnの依存関係を解決。

Last updated at Posted at 2021-12-24

docker-compose upで

RUN yarn upgrade

の部分でエラーがでた。

Step 13/19 : RUN yarn upgrade

It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files.

そのとおりでしかないので、package-lock.jsonを消した。npmとyarnを混在させてた。packge.jsonをどっちも使うから互換性あると思ってたが、lockファイルはまた別の話か。

 The engine “node” is incompatible with this module

が核となる部分か。

error @npmcli/fs@1.1.0: The engine "node" is incompatible with this module. Expected version "^12.13.0 || ^14.15.0 || >=16". Got "10.24.0"

nodeのバージョンが古いと怒られてる気がする

node -v
v16.13.1

ローカルではこうだったが、docker上では Got "10.24.0"となってるので
16系のnodeをインストールするDockerfileを記述したい。

Dockerfileにこのように記述してみた。


RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - && \ #←ここ変更
    apt-get install -y nodejs

 docker-compose upを実行。

RUN yarn upgrade

を突破した!!!やったぜ!!

coffee_passport_webpacker_1 exited with code 1

しかしwebpackerコンテナはこのようになってた。。

依存関係がやばいからだとおもうので、過去の自分の記事を参考に


https://qiita.com/divclass123/items/5cee396071540256e11e

Dockerfileに


RUN yarn upgrade-interactive --latest


これをついか。

この記事のように、このコマンドは対話型で、依存関係を直していくので、
RUN yarn upgrade-interactive --latest
このコマンド書くだけでは不十分なのではないか。

実際自分がローカルで、yarn upgrade-interactive --latestを叩いたときには

対話型の画面になって、aを押した後にエンターを押した。

RUN a
RUN enter
とドッカーファイルに書くことができればいいのだが。。。

もしくは、COPY . /coffee_passport
でキャッシュが使われてる気がするので、

ローカルで依存を直しても、依存を直す以前のディレクトリがコピーされていたら全く意味がないので

docker-compose build --no-cache

を実行する必要があるのではないか。


Step 15/21 : RUN yarn upgrade-interactive --latest
 ---> Running in 5330c7208d1b
yarn upgrade-interactive v1.22.17
success All of your dependencies are up to date.
Done in 6.03s.

とdocker-composeのログをみたらなっていた。

つまり

 RUN yarn upgrade-interactive --latest

単体でも機能していた。
これで依存関係が治ればいいのだが、、。。。

依存関係とは別のエラーがでた。。。一旦dockerをまっさらにして、やり直そう。

コンテナが止まらないので、再起動。

すべてのネットワークと、ボリューム、コンテナを削除できた。

docker-compose build --no-cache

を実行。
--no-cacheつける意味ない気がするが念には念を

くそほど、長くロードされてる。

webpackerコンテナ全体のログはこんな感じ




TypeError: Class constructor ServeCommand cannot be invoked without 'new'

をググったら。

```

これは今のところうまくいきました。package.jsonファイルのwebpack-dev-serverバージョンを次のように変更します。

"webpack-dev-server": "~3"
そして、yarn installまたはを実行しnpm installます。

とかいてあったので




webpack-dev-serverをバージョン3のままにする
これを行うには、package.jsonファイルを更新します。

package.json

```
"webpack-dev-server": "~3"

```

をこうする。

```

- RUN bundle exec rails webpacker:compile

```

```
- RUN yarn upgrade-interactive --latest


```


をけした。コンパイル専用のコンテナがあるので、わざわざDockerfileに記述しなくてもいいとおもった。

- RUN yarn upgrade-interactive --latest

は

"webpack-dev-server": "~3"とバージョンを固定したいので、

アップデートをしてしまうコマンドを削除

```
RUN yarn install --check-files
```

を追記




```

docker-compose up

```


で成功!!

やったぜ!!
