多python环境。它同时安装了Python 2.7.15和3.7.2。

常规（Python2）pip正常运行。

当我尝试运行时pip3 install flask，出现以下错误：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting flask

我有一个代码可以从 MongoDB 读取特定格式的数据。我需要测试一下。

为此，我使用要测试的数据创建了一个 JSON：

{
  "id": ObjectId("57552e32e4b0839ede67e0af"),
  "serial" : 574000690,
  "startDate" : ISODate("2016-08-22T23:01:56.000Z"),
  "endDate" : ISODate("2016-10-22T22:01:56.000Z"),
  "reason": ""
}

这是应该创建的对象：

public static class MyObject implements Serializable{
    private String id;
    private long serial;
    private Date startDate;
    private Date endDate;
    private String reason;
}

我有一个读取 JSON 文件并创建 Mongo 文档并写入数据库的代码：

List<Document> docs = dirAsDbObjects(dir + File.separator + 
subDir.getName()).collect(Collectors.toList());

docs.forEach(docManipulator);
docs.forEach(doc -> doc.putIfAbsent("_id", new ObjectId()));

ret.addAll(docs);

MongoDatabase db = mongoClient.getDatabase(dbName);
MongoCollection<Document> coll = db.getCollection(subDir.getName());

List<InsertOneModel<Document>> inserts = docs.stream().map(InsertOneModel::new).collect(Collectors.toList());
coll.bulkWrite(inserts);

写入数据后，有一段代码会尝试从 MongoDB 读取数据并将其填充到MyObject …
