在Windows 7上安裝mysql2 gem時出錯

Question

我正在使用以下命令安裝mysql2 gem：

gem install mysql2 -- '--with-mysql-include="C:\Program Files\MySQL\MySQL Server 5.6\include" --with-mysql-lib="C:\Program Files\MySQL\MySQL Server 5.6\lib"'

但低於錯誤

C:\Ruby200\bin>gem install mysql2 -- '--with-mysql-include="C:\Program Files\MyS
QL\MySQL Server 5.6\include" --with-mysql-lib="C:\Program Files\MySQL\MySQL Serv
er 5.6\lib"'

Building native extensions with: '--with-mysql-include="C:\Program Files\MySQL\M
ySQL Server 5.6\include" --with-mysql-lib="C:\Program Files\MySQL\MySQL Server 5
.6\lib"'
This could take a while...
The system cannot find the path specified.

我不明白是什么原因造成的，因為提到的所有目錄已經存在。

以下是我的寶石環境

C:\Ruby200\bin>gem env

我總是收到“系統找不到指定的路徑。”。 這可能是這個原因。 我嘗試在安裝時包括mysql dir和mysql config，但沒有成功。

以下是我在使用mysql連接器時遇到的錯誤：

Answer 1

做對了

您需要做的就是重新安裝sql並確保要安裝的文件夾名稱中沒有空格，然后下載更新的連接器mysql-connector-c-6.1.5-winx64.msi升級隨附的連接器與mysql完整版。

之后，將文件mbsql.dll從msql復制到ruby文件夾，我假設您已經知道，如果沒有，這張圖片應該可以幫助您https://medium.com/@frontlineutils/installing-the-mysql2-rubyonrails-gem-on-windows -7-8-a028f44d87f3

再次運行gem安裝，例如gem install mysql2-'--with-mysql-include =“ C：\\ Files \\ MySQL56 \\ include” --with-mysql-lib =“ C：\\ Files \\ MySQL56 \\ lib”'

那就是我正確的方式。

Answer 2

WIN7 X64位或32位？

您是否安裝過DevKit ？

或安裝mysql-connector- （下載存檔版本）並使用

  gem install mysql2 --platform=ruby -- '--with-mysql-dir="D:\mysql-connector"'
