在我的Dockerfile我有下一個命令：
FROM perl:5.30.3-buster
...
RUN env && source $PERLBREW_ROOT/etc/bashrc && env && carton install
source $PERLBREW_ROOT/etc/bashrc執行時PERL5LIB消失并且carton找不到PERL5LIB路徑指示的庫
命令的輸出：
Step 18/22 : RUN env && source $PERLBREW_ROOT/etc/bashrc && env && carton install

請告訴我，Docker在構建容器時從檔案運行該命令時有什么問題？
uj5u.com熱心網友回復：
謝謝@ikegami
是unset由${PERLBREW_HOME:-}/init. unset當您在 perls 之間切換并且不希望他們的庫相互混合時，這是必需的。
例如，您在 perl-5.24 上并已將庫安裝到其中PERL5LIB，然后您切換到 perl-5.28 但PERL5LIB仍指向由不同版本的 perl 安裝的模塊。這可能會導致核心轉儲。
