安裝 eventmachine gem 時出錯

Question

當我運行foreman start ，出現以下錯誤：

pallav@pallav-System-Product-Name:~/Workspace/Aadvisor$ foreman start

我也做了

sudo bundle install

再次報錯：“安裝 eventmachine (0.12.10) 時出錯，Bundler 無法繼續。請確保在打包前 gem install eventmachine -v '0.12.10' 成功。”

現在當我做

sudo gem install eventmachine -v '0.12.10'

我再次收到錯誤消息：

"ERROR: Error installing eventmachine: ERROR: Failed to build gem native extension."

請告訴我我缺少什么。

Answer 1

為了在 Ubuntu 14.04 上安裝eventmachine 1.0.3 ，您首先需要運行：

sudo apt-get install build-essential

然后bundle install或gem install eventmachine

應該夠了。

注意：如果你有 rbenv，記得在bundle install之后運行rbenv rehash 。

Answer 2

嘗試安裝 openssl 和 libstdc++。
如果您使用 rvm 並在單用戶模式下安裝了 ruby​​，則應省略 sudo。

你能粘貼完整的錯誤日志嗎？ 用那個回答你的問題會更容易。

更新請在另一個stackoverflow線程中參考這個答案https://stackoverflow.com/a/17386686/846970 ，讓我知道它是否有效。

Answer 3

您需要運行bundle install您的機器上沒有安裝 Gemfile 中所需的 gem 之一。

Answer 4

嘗試更新您的系統 RubyGems。

1. rvm 穩定
2. rvm ruby​​gems 最新

我希望這對你有用。

Answer 5

對於無法使用上述方法解決的其他人：

sudo -u gitlab -H bundle config build.eventmachine --with-cflags=\"-O2 -pipe -march=native -w\"
sudo -u gitlab -H bundle config build.thin --with-cflags=\"-O2 -pipe -march=native -w\"

正如用戶所描述恩里科這里。

Answer 6

嘗試gem install eventmachine -- --with-openssl-dir=/usr/local/opt/openssl@1.1
