Question

我已经安装了包envoy。我运行了脚本，但发生了一个Windows错误。我评论了envoy.run，然后运行完整的脚本，但是当我删除注释时，会发生错误。

 import envoy

 # This data is checked-in to the repository and is a compressed 
 # version of the output from Example 3

 F = 'resources/ch06-mailboxes/data/enron.mbox.json.bz2'

 r = envoy.run("bunzip2 %s" % (F,))
 print r.std_out
 print r.std_err

脚本追溯：

 Exception in thread Thread-9:
Traceback (most recent call last):

Answer 1

请试试这个：

F = os.path.join(os.getcwd(), 'resources/ch06-mailboxes/data/enron.mbox.json.bz2')

如何在python中使用envoy包？
