python - 命令出错，退出状态为一

Question

我正在我的电脑(Windows 7)中安装 qark 用于测试目的。我已经安装了 python 3.7.2 和 pip 19.2.3。对于下一步，我必须在安装时安装 requirement.txt 文件，发生错误(命令错误，退出状态 1:)我将在下面给出完整的错误。

我尝试再次安装它，但错误仍然存​​在，我不知道该怎么办。帮我。 谢谢

Answer 1

我也遇到了类似的问题，cmd/PowerShell 告诉我缺少一个版本的 Windows Visual C++，所以我按照 THIS 上的内容进行操作站点，所以我没有再遇到这个问题(为了安全，我也重新启动了):

1. Install using any ONE of these choices:
   • Microsoft Build Tools for Visual Studio
   • Alternative link to Microsoft Build Tools for Visual Studio.
   • Offline installer: vs_buildtools.exe
2. Select: Workloads → C++ build tools.
3. Install options: select only the “Windows 10 SDK” (assuming the computer is Windows 10). Optionally, if you want to use MSVC cl.exe C/C++ compiler from the command line, additionally select the C++ build tools, which takes an additional 2 GB disk space.

此外，为了避免出现问题，我更喜欢安装 Python 2.7.13 或 3.6 因为它们是经过测试的(如 github page 上的要求所示)。

之后(再次根据说明)我使用以下方法安装了 QARK:

pip install -r requirements.txt
pip install . --user

最后，为了让它工作，我必须将这些定义放入环境变量的路径中: C:\Users\user\AppData\Roaming\Python\Scripts (如果您使用的是 Python 2.x.x) C:\Users\utente\AppData\Roaming\Python\Python36\Scripts (如果您使用的是 Python 3.x.x)

之后我运行它就没有任何问题了。
希望对您有所帮助! 🤞
