錯誤：命令“gcc”以退出狀態失敗 - 在 docker centos 上安裝 ibm_db 時

Question

我正在嘗試安裝 ibm_db - python3.6 但無法安裝 pip。 在 python 2.7 上安裝成功，但在 3.6 上它拋出 gcc 錯誤

Docker 文件

RUN yum -y install python3
RUN yum install -y python34-devel python-devel centos-release-scl gcc libssl-dev openssl yum install gcc openssl-devel bzip2-devel libffi libffi-devel

RUN python --version
RUN which python
RUN pip --version
RUN python3 --version
RUN which python3
RUN pip3 --version

RUN python3.6 -m pip install -r scripts/requirements.txt

要求.txt

ibm_db==3.0.2
ibm-db-sa==0.3.5
SQLAlchemy==1.3.18

下面的 Dockerfile 是用於當前版本的 ibm_db 和 ibm_db_sa 的映像，以及用於 centos7 的 SQLAlchemy。

它適用於 x64 架構，無需編譯 ibm_db。

更改 Dockerfile 以省略映像中不需要的包。 較小的圖像可以更快地構建並使用更少的存儲空間。

此 Dockerfile 顯示了將預配置的db2dsdriver.cfg復制到默認位置的映像的可選步驟。

這讓我在使用 python ibm_db 之前，可以在容器中使用db2cli來確保與數據庫的連接。

db2cli 需要 LD_LIBRARY_PATH 來包含 clidriver\lib 目錄，以確保 db2cli validate 將運行。
