Shell脚本中其他意外标记附近的语法错误

Question

我有这个带2个参数的shell脚本，但是运行时它会向我显示此错误。要正确编写此if-then-else块我需要做什么？

NK_BILLED_UNBILLED_DATA.sh：第31行：意外令牌else' 'K_BILLED_UNBILLED_DATA.sh: line 31:以外的语法错误

Shell脚本

if test -d $2;then

        echo "Welcome $2"

        echo "Not Exist";

        fi

    else 

    export REPORT_GEN_PATH=$WORK/Reports/ANT001A_REQ01/generated_reports;
