我正在学习本教程http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world/page/5

当我virtualenv flask命令时,我收到此错误消息:

Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

这是有道理的,因为virtualenv的目的是创建一个你可以控制的新环境,--user命令将所有内容放在一个特定的位置,从而破坏开发环境分离的目标.

看来pip默认--user安装,我可以更改此默认行为吗？而且,更好的是,我可以随时获得与virtualenv一起玩的好处吗？

为了澄清,这是我的终端的样子.

MELCHIOR:miguelgrinberg-microblog megablanc$ virtualenv flask

我正在尝试模拟对第三方服务的一些 API 调用以进行单元测试。我真的只是希望这个模拟函数RestEase.Response<...>每次都返回相同的值。

// Setup
var VeracrossMock = new Mock<IVeracrossAPI>(MockBehavior.Strict);
Func<List<VeracrossStudent>> func = () => new List<VeracrossStudent>() { new VeracrossStudent() { First_name = "Bob", Last_name = "Lob" } };
RestEase.Response<List<VeracrossStudent>> resp = new RestEase.Response<List<VeracrossStudent>>("", new HttpResponseMessage(HttpStatusCode.OK), func);

// Problem is on the line below
VeracrossMock.Setup(api => api.GetStudentsAsync(1, null, CancellationToken.None)).ReturnsAsync<RestEase.Response<List<VeracrossStudent>>>(resp);

它给了我一个红色下划线，然后声称ReturnsAsync不存在，或者至少不存在我给出的论点。

Error CS1929 'ISetup<IVeracrossAPI, Task<Response<List<VeracrossStudent>>>>' does not contain a definition for 'ReturnsAsync' and the best extension method overload 'SequenceExtensions.ReturnsAsync<Response<List<VeracrossStudent>>>(ISetupSequentialResult<Task<Response<List<VeracrossStudent>>>>, Response<List<VeracrossStudent>>)' requires a receiver of type 'ISetupSequentialResult<Task<Response<List<VeracrossStudent>>>>'

我应该如何使用 …

所以我无法加载 ROracle。我确实对此很陌生，因此任何信息都值得赞赏，任何有关提供哪些进一步信息的信息也会有所帮助。

> library(ROracle)
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared object '~/R/x86_64-pc-linux-gnu-library/2.14/ROracle/libs/ROracle.so':
  libclntsh.so.11.1: cannot open shared object file: No such file or directory
Error: package/namespace load failed for ‘ROracle’

ROracle.so 正是它所说的位置。libclntsh.so.11.1 可以在/usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1. 这是结果.libPaths：

> .libPaths()
[1] "/home/nguiller/R/x86_64-pc-linux-gnu-library/2.14" "/usr/local/lib/R/site-library"                     "/usr/lib/R/site-library"                          
[4] "/usr/lib/R/library"                                "/usr/lib/rstudio/R/library" 

我的 .Renviron 文件

LD_LIBRARY_PATH="/usr/lib/oracle/11.2/client64/lib:/home/nguiller/Downloads/instantclient_11_2"
ORACLE_HOME="/usr/lib/oracle/11.2/client64/:/home/nguiller/Downloads/instantclient_11_2"
OCI_LIB="/usr/lib/oracle/11.2/client64/lib"

由于 OCI 库，我在开始安装 ROracle 时遇到了很多麻烦，但它最终与 R CMD INSTALL --configure-ags='--with-oci-lib=/usr/lib/oracle/11.2/client64/lib --with-oci-inc=/usr/include/oracle/11.2/client64' ROracle_1.1-8.tar.gz

让我知道我可以如何提供帮助。

当我想将其保留为控制台应用程序时（最终将保留），我看到的每个示例都使用 Form ，因此在此方面并没有走得太远。

以下代码每次使用EIPAbstractError: IPProcs is not defined. Make sure IPPeerCommon() is in the uses clauses.

将其添加到 Uses 子句中 No peer with the interface guid [xxx-xx...]

program EMV_ConsoleTest;

{$APPTYPE CONSOLE}

{$R *.res}

uses
  System.SysUtils, REST.Client;

var
  LClient: TRESTClient;

begin
  try
    LClient := TRESTClient.Create('http://localhost:9000/');
  except
    on E: Exception do
      Writeln(E.ClassName, ': ', E.Message);
  end;
end.

我得到以下行为。在此settings.py代码段中，从第33行点击“ o”

31# Application definition
32 
33 INSTALLED_APPS = [
34     'rest_framework',

我明白了

31# Application definition
32 
33 INSTALLED_APPS = [
34         |<-cursor is here, two indents, 8 spaces
35     'rest_framework',

我真正想要的是一个缩进或总共4个空格，与列表的其余部分一致。是什么赋予了？我正在使用以下.vimrc文件，我从这里开始大多抄写。

set nocompatible              " required
