参照论坛教程安装完dc2010后，输入dc出现如下提示，哪位大侠能帮解决一下！

/home/eda/synopsys/dc/bin/dc_shell: line 330: /home/eda/synopsys/dc/linux/syn/bin/common_shell_exec: No such file or directory
/home/eda/synopsys/dc/bin/dc_shell: line 330: exec: /home/eda/synopsys/dc/linux/syn/bin/common_shell_exec: cannot execute: No such file or directory

环境变量设置如下：
export PATH=/home/eda/synopsys/scl/linux/binPATH

alias lmlim3="lmgrd -c /home/eda/synopsys/license/synopsys.dat -l ~/syn_lic.log"

export PATH=/home/eda/synopsys/dc/binPATH
export SYNOPSYS=/home/eda/synopsys/dc
export DC_HOME=/home/eda/synopsys/dc
export SNPSLMD_LICENSE_FILE=27000@localhost

alias dc="dc_shell"
alias dv="design_vision"
