You may have not created yet the virtual environment called "flask" (explained under the Installing Flask section), therefore the shebang line fails. I ran it without and with the virtenv and it works.
您可能尚未创建名为“flask”的虚拟环境(在“安装Flask”部分下进行了解释),因此shebang行失败。我没有和virtenv运行它,它的工作原理。
Check this topic to see if it helps: flask/bin/pip install flask==0.9 results in 'no such file or directory'.
检查此主题以查看它是否有帮助:flask / bin / pip install flask == 0.9导致'无此文件或目录'。
