Question

我在尝试grep查看日志中包含多行行的消息时遇到以下错误...有人可以提供有关如何克服此错误的输入吗？

代码： -

    print gerrit_commitmsg
    gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE)
    print gerritlog

错误： -

Commit message:-

Build system changes

Build system changes to include packages in the build

    gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE)

    raise TypeError("bufsize must be an integer")

subprocess.Popen类需要一个像这样的参数列表：

Popen(args, bufsize=0, ...)

所以你传递了它：

args = git
bufsize = log

因此错误（bufsize需要一个整数值）。命令向量需要是一个列表，如下所示：

gerritlog = Popen(['git','log','--grep','gerrit_commitmsg'], stdout=PIPE, stderr=PIPE)

在grepping消息时，bufsize必须是整数错误
