我刚刚安装了pipenv，然后运行了pipenv-istall-pymysql，成功完成了安装。但是，当尝试将pymysql与导入pymysql一起使用时，我得到一个“无法导入‘pymysql’”。

这是我的文件：

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
pymysql = "*"

[requires]
python_version = "3.7"

还有皮普尔。锁定：

                "verify_ssl": true
            }
        ]
    },
    "default": {

            ],
            "index": "pypi",
            "version": "==0.9.3"
        }
    },
    "develop": {}
}

pipenv在哪里安装这些软件包？我在我的项目文件夹中看不到任何内容。。。
