如何修复FileNotFoundError[WinError 2]？

Question

我正在尝试将Proton VPN Linux CLI（https://github.com/ProtonVPN/linux-cli）移植到Windows，到目前为止已经取得了不错的成功，但是我遇到了[subprocess.Popen（）]的问题。我尝试了许多修复方法，但迄今为止没有一个有效。我已尝试将其转换为：

    with open(os.path.join(CONFIG_DIR, "ovpn.log"), "w+") as f:
        subprocess.Popen(
            [
                "openvpn",
                "--config", OVPN_FILE,
                "--auth-user-pass", PASSFILE,
                "--dev", "proton0",
                "--dev-type", "tun"
            ],
            stdout=f, stderr=f
        )

从最初的模块到以下模块：

    file_name = os.path.join(CONFIG_DIR, "ovpn.log")
    print(file_name)
    with open(file_name, "w+") as f:
        subprocess.Popen([
            "openvpn",
            "--config", OVPN_FILE,
            "--auth-user-pass", PASSFILE,
            "--dev", "proton0",
            "--dev-type", "tun"
        ], stdout=f, stderr=f)

两者都会产生相同的错误：

Traceback (most recent call last):

FileNotFoundError: [WinError 2] The system cannot find the file specified

有人能帮我吗？我已经为此挣扎了一整天，但一直找不到解决办法。（顺便说一下，我对python非常陌生）

编辑：在尝试从原始模块打印“f”时，它返回以下内容-“<；io.TextIOWrapper name='C:\Users\\.pvpn cli\ovpn.log'mode='w+'encoding='cp1252'>；”。我尝试将名称输入到浏览器选项卡中，收到一个错误，但在删除双斜杠后，我被带到文件中。我很确定双斜线应该在那里，但这可能是问题所在吗
