Python：BufSize必须是整数

Question

我试图在我的Python脚本中运行它：

for i in array:
    subprocess.Popen("python ~/path/myMrjob.py", "--domain "+i, "~/otherPath/* > ~/otherPath2/"+i+"/output-unsorted.log")

我看到了：TypeError: bufSize must be an integer

Answer 1

您应该将要发送到shell的字符串列表传递给Popen as the first argument：

for i in array:
    subprocess.Popen(["python ~/path/myMrjob.py", "--domain "+i, "~/otherPath/* > ~/otherPath2/"+i+"/output-unsorted.log"])
