macを使用しており、このガイドに従っています:https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-macos-for-development/15772。

次のコマンドを実行しました:
bundle exec rake db:create db:migrate
RAILS_ENV=test bundle exec rake db:create db:migrate

しかし、以下のエラーが表示されました:

Could not find nokogiri-1.8.5 in any of the source
Run "bundle install" to install missing gems.

bundle installを実行しましたが、途中でエラーが発生しました。その内容は以下の通りです:

Sorry. Here’s the error(In text)

Make sure that gem install pg -v '1.1.3' --source 'https://rubygems.org/' succeeds before bundling.

Sounds like you’re having trouble getting pg (postgres) installed. You’ll need to check the specific error logs to see why.

Here’s the log(Which is extremely long and confusing):

Your computer is having trouble compiling things if you read the first error there.

ld: warning: ignoring file /usr/local/lib/libpq.dylib, file was built for x86_64 which is not the architecture being linked (i386): /usr/local/lib/libpq.dylib

Try searching in Google for the relevant error, above.

I can’t seem to run bash <(curl -s https://raw.githubusercontent.com/techAPJ/install-rails/master/mac), and it returns an error sh: syntax error near unexpected token(’`

Were any messages output before the error? You’ve not given any indication whether the script ran at all, or threw an error part-way.

偶然にもこのトピックが再び話題になって嬉しいです。この問題はしばらく前から存在しており、Apple Silicon Macに限ったことではないようです。

私もM1 iMacであなたと同じガイドに従って同じ問題を抱えていました。@blakeさんが素晴らしく、私にとって回避策を見つけてくれました。:grinning:

M1 Macで動作させることができました。問題が正確には何なのかはよくわかりませんが、使用できる回避策は以下のとおりです。

最初のターミナルタブから以下を実行します。

bin/rails server --binding 127.0.0.1

2番目のターミナルタブから。discourseディレクトリ内のこのディレクトリに変更します。

cd app/assets/javascripts/discourse

次にこのコマンドを実行します。

ember server --proxy http://127.0.0.1:3000

その後、http://localhost:4200 にアクセスしてください。

新しいエラーが発生しました

わかりません。M1 Mac では ember server --proxy を使用する必要はなくなりました。通常の方法は、Discourse のルートディレクトリ内でターミナルタブを 1 つ開き、bin/ember-cli -u を実行することです。これにより、1 つのコマンドで Rails と Ember の両方のサーバーが実行されます。それを試してみて、機能するかどうか確認してもらえますか?

ありがとうございます!!!!!! :smiling_face:
