`os.system` 无法找到由 `with open` 创建并由 `with open` 读取的文件

Question

在 Python3 程序运行中 Windows 10，os.system() 无法找到在 APPDATA 目录中使用 with open，即使同一文件可以被后续 with open.

成功读取

此 OP 的问题：

What specific syntax needs to be changed in the Python3 code below in order to successfully create a file in the APPDATA directory that can be found visually by users of the Windows 10 Explorer UI and also programmatically by the os.system() command below which is failing?

当前代码：

下面的代码是我们目前正在尝试的：

print(os.getenv('APPDATA'))
terraformRC = os.path.join( os.getenv('APPDATA'), "terraform.rc")
print("terraformRC is: ", terraformRC)
print("About to write terraformRC. ")
try: 
  with open(terraformRC, 'w') as f:
    f.write('provider_installation {\n')
    f.write('  filesystem_mirror {\n')
    f.write('    path    = "' + providersPath + '"\n')
    f.write('    include = ["*/*"]\n')
    f.write('  }\n')
    f.write('\n')
    f.write('  direct {\n')
    f.write('    exclude = ["*/*"]\n')
    f.write('  }\n')
    f.write('}\n')
except (Exception) as e:
  print(e)

print("About to read the terraformRC we just wrote.  ")
with open(terraformRC, 'r') as lines:
  for line in lines:
    print(line)

print("About to disable settings for folder so that the terraformRC file can be unhidden.  ")
removeSettingsCmd = 'attrib -h -s ' + terraformRC
os.system(removeSettingsCmd)

当前失败的结果：

当我们从 Windows CMD 调用上述 Python3 代码时，Windows CMD 会打印以下输出。

C:\path\to\AppData\Roaming
terraformRC is:  C:\path\to\AppData\Roaming\terraform.rc
About to write terraformRC.
About to read the terraformRC we just wrote.
provider_installation {
  filesystem_mirror {
    path    = "C:\path\to\dependencies\terraform\providers"
    include = ["*/*"]
  }
  direct {
    exclude = ["*/*"]
  }
}

About to disable settings for folder so that the terraformRC file can be unhidden.
File not found - C:\path\to\AppData\Roaming\terraform.rc

问题：

从上面的输出可以看出，Python似乎成功找到了APPDATA目录。然后 Python 似乎成功将 terraformRC 文件写入 APPDATA。然后 Python 似乎成功读取了它似乎刚刚写入 APPDATA.

的 terraformRC 文件

问题是 os.system(removeSettingsCmd) 然后失败并显示一条消息 File not found - C:\path\to\AppData\Roaming\terraform.rc，指出它无法在正确的位置找到 terraformRC 文件。而且，当使用 Windows Explorer 在 APPDATA 中查找 terraformRC 文件时，人类用户无法查看它。

您似乎已经从 Microsoft Store 安装了 Python。商店应用程序是通用 Windows 平台 (UWP) 应用程序，并基于每个用户将 AppData 存储重定向到 attrib 等本机应用程序不知道的唯一用户特定区域。有关详细信息，请参阅 UWP - store and retrieve settings and other app data。

我建议卸载 Python 的 UWP 版本并安装来自 python.org 的官方本机二进制文件，这将如您所愿。
