Bundle Install命令不會安裝我的寶石？

Question

好的，所以我對Rails很陌生，並且剛剛開始嘗試使用我的新Linux操作系統。

我正在為學校做一個項目，我已經完成了所有的指示。 出於一致性目的，他們需要rails和gemsets的特定版本。

在我的目錄中初始化了rails之后，我運行了一個bundle install命令，並且我在代碼塊中遇到了幾個安裝問題，如下所示：

user@user-ThinkPad-T430 ~/code/bloccit $ sudo bundle install
[sudo] password for user: 
Don't run Bundler as root. Bundler can ask for sudo if it is needed, 
and installing your bundle as root will break this application for all
non-root users on this machine.

An error occurred while installing json (1.8.6), and Bundler cannot

Make sure that `gem install json -v '1.8.6'` succeeds before bundling.

主要錯誤似乎是Gem::Ext::BuildError: ERROR: Failed to build gem native extension. 但是它在捆綁器中安裝json時也遇到了問題。

任何有用的建議或提示將不勝感激！

Answer 1

首先按照說明（請避免sudo ）：

不要以root身份運行Bundler。 如果需要，Bundler可以請求sudo，並且以root身份安裝捆綁包將破壞此計算機上所有非root用戶的應用程序。

要在linux解決此問題，請運行：

sudo apt install ruby2.3-dev

干杯!
