.bashrc 说:
PATH=$PATH:/usr/local/mysql/bin/:$HOME/.rvm/bin # Add RVM to PATH for scripting
但mysql -u root返回
mysql -u root
-bash: mysql: command not found
但如果我这样做/usr/local/mysql/bin/mysql -u root 一切正常。为什么不使用 PATH 进行搜索?
/usr/local/mysql/bin/mysql -u root
谢谢
您需要使用:
export PATH=$PATH:...
或者export PATH在此语句之后添加语句。
export PATH
您所做的更改不会在您的.bashrc. export在分配之前添加(或export PATH稍后添加)将确保您的更改导出到 shell 的子进程。
.bashrc
export
我不太了解python,但从文档中我可以看出代码:
str = "AAAA" str += pack("<I", 0)
会将pack函数的结果附加到str,这将是little-endian风格的整数值0。我的问题是 C 等价物是什么。会不会是:
char str[20] = "
