我跑npm run start,服务器运行正常.当我尝试查看客户端时localhost,服务器返回错误:GET/500 62.700 ms - 2028错误:无法在视图目录"/ views"中查找视图"错误"
只使用源文件时,应用程序运行正常.从webpack bundle运行应用程序时发生此错误.
导致此错误的源文件和捆绑文件之间有什么区别？
webpack.config.js
var webpack = require('webpack');
var path = require('path');
var nodeModules = {};
fs.readdirSync('node_modules')
.filter(function(x) {
return ['.bin'].indexOf(x) === -1;
})
.forEach(function(mod) {
nodeModules[mod] = 'commonjs ' + mod;
});
module.exports = [
{
entry: {
'app_bundle': './server.js'
},
target: 'node',
query: {
cacheDirectory: true,
presets: ['es2015']
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel',
exclude: /node_modules/
} …将ref-struct实例嵌套在另一个实例中,嵌套对象的其中一个属性在手动垃圾回收时会损坏.

请注意日志输出的第3行,其值name未损坏:

我想生成 6 个随机数，将它们推送到一个向量上，然后使用rustc_serialize该向量将该向量编码为 NodeJS使用的 JSON 字符串。
extern crate rand;
extern crate rustc_serialize;
use rand::{OsRng, Rng};
use rustc_serialize::json::{self, Json, ToJson};
#[no_mangle]
pub extern "C" fn generate() -> String {
let choices: [u8; 6] = [1, 2, 3, 4, 5, 6];
let mut rand_vec: Vec<u8> = Vec::new();
let mut rng = match OsRng::new() {
Ok(t) => t,
Err(e) => panic!("Failed to create OsRng!, {}", e),
};
for _ in 0..5 {
rand_vec.push(*rng.choose(&choices).unwrap());
}
json::encode(&rand_vec).unwrap()
}
这段代码被编译为一个库generate_6_rand.dll。我有一个单独的二进制文件，用于测试此代码。
