python - 如何解决导入错误: no module named tarfile

Question

我无法在 python 脚本中使用 tarfile 模块。

当我运行脚本时，我收到错误“ImportError:没有名为 tarfile 的模块”

如果我删除“导入 tarfile”，那么它会在 tarfile.open 处失败；错误提示--NameError: tarfile

def make_tarfile(output_filename, source_dir):
    tar = tarfile.open(output_filename, "w:gz")
    #tar.add(source_dir, arcname=os.path.basename(source_dir))
    tar.add(source_dir)
    tar.close()

子流程模块也发生同样的事情。我已经验证了这些模块并且它们存在。请注意，所有模块都在 python 控制台或命令行中工作

我需要 50 声望才能发表评论，所以我会留下答案:

您能否将以下行添加到您的脚本中:

print sys.version

只是为了绝对确保运行脚本的 Python 版本与您用作解释器的版本相同。就像人们所说的，也许某个地方的环境变量被覆盖，导致错误的Python版本运行脚本。
