定义将在所有新的conda环境中安装的软件包

Question

我希望能够定义应在我的所有conda环境中安装的标准软件包的列表。例如。当我创建一个新环境时，我知道我将始终需要jupyterlab，numpy，matplotlib，pandas等，如果我不必在创建的每个新环境中都安装它们，那就太好了。

总有可能吗？我在文档或互联网上的其他地方都找不到任何东西，但是也许我错过了一些东西……

示例

现在，当我创建一个新环境时，必须手动指定在该环境中需要哪些软件包。因此，每次创建新环境时，我都必须

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton(Configuration);

        SecretsMangerClientFactory secretsMangerClientFactory = new SecretsMangerClientFactory();
        AWS.ConfigurationProvider configurationProvider = new AWS.ConfigurationProvider(secretsMangerClientFactory);
        var awsCognitoClientOptions =  configurationProvider.GetAsync<AWSCognitoClientOptions>(Constants.AppSettings.CognitoSettings).GetAwaiter().GetResult();
        services.AddSingleton(awsCognitoClientOptions);
        services.AddCognitoIdentity();

        services.AddMvc()
                .AddJsonOptions(options =>
                {
                    options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
                    options.SerializerSettings.Converters = new[] { new EncryptionKeyConvertor() };
                    options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
                })
                .AddRazorPagesOptions(options =>
                {
                    options.AllowAreas = true;
                });

        services.AddAntiforgery(o => o.HeaderName = "XSRF-TOKEN");

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                .AddCookie();

        services.ConfigureApplicationCookie(options =>
                {
                    options.LoginPath = new PathString("/Applications/Identity/Login");
                    options.AccessDeniedPath = new PathString("/AccessDenied");
                });

        services.ApiVersioning();
        services.AddMemoryCache();

        ObjectFactory.Initialize(new ContainerFactory(), GetModules());
        var container = (ObjectFactory.GetContainer() as DependencyContainer).InnerContainer;
        container.Populate(services);

        RegisterMonotone();

        return container.GetInstance<IServiceProvider>();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            app.UseHsts();
        }

        app.UseEnableRequestRewind();
        app.UseCors(builder => builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod());
        app.UseMiddleware<CryptoCallContextInjectorMiddleware>();
        app.UseMiddleware<ExceptionHandlerMiddleware>();
        app.UseMiddleware<ProfilerInjectorMiddleware>();
        app.UseMiddleware<APIKeyValidatorMiddleware>();

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();

        app.UseAuthentication();

        app.UseMvc();
    }

这很繁琐，因为我需要很多软件包。

当前解决方法

当前，我的主目录中有一个Shell脚本可以执行此工作，因此，如果我创建一个新环境，则只需要运行此脚本即可。但是，如果我能告诉conda在所有新环境中自动安装这些软件包，那就太好了。

#export the current environment to yml file (txt file)
conda env export > environment.yml 
# this will create new environment with all packages same as previous environment
conda env create -f environment.yml
