typescript 打字稿错误 TS1005: ';' 预期（二）

TypeScript error TS1005: ';' expected (II)

提问by StockUberflow

First of all, I've already seen the other posts about error TS1005. Same error code, but totally different.

首先，我已经看过其他关于错误 TS1005 的帖子。相同的错误代码，但完全不同。

A simple let x: number;will generate the error TS1005during compilation. It's not about a missing semicolon as what the error message says, but the compiler does not recognize the let keyword. I read that maybe because of an outdated compiler.

一个简单的let x: number;将error TS1005在编译期间生成。这与错误消息所说的缺少分号无关，而是编译器无法识别 let 关键字。我读到这可能是因为一个过时的编译器。

Here's my typescript version installed using npm install -g typescript

这是我安装的打字稿版本 npm install -g typescript

• TypeScript version: 2.5.2
• Compiler (tsc) version: 1.0.3.0

• 打字稿版本： 2.5.2
• 编译器 (tsc) 版本： 1.0.3.0

Maybe somebody can help?

也许有人可以帮忙？

Your installation is wrong; you are using a very old compiler version (1.0.3.0).

你的安装有误；您使用的是非常旧的编译器版本 (1.0.3.0)。

tsc --versionshould return a version of 2.5.2.

tsc --version应该返回 2.5.2 的版本。

Check where that old compiler is located using: which tsc(or where tsc) and remove it.

使用：（which tsc或where tsc）检查旧编译器所在的位置并将其删除。

Try uninstalling the "global" typescript

尝试卸载“全局”打字稿

npm uninstall -g typescript

Installing as part of a local dev dependency of your project

作为项目的本地开发依赖项的一部分安装

npm install typescript --save-dev

Execute it from the root of your project

从项目的根目录执行它

./node_modules/.bin/tsc

You haven't the last version of typescript.

你还没有打字稿的最新版本。

Running :

跑步 ：

npm install -g typescript

npmchecks if tsccommand is already installed.

npm检查tsc命令是否已经安装。

And it might be, by another software like Visual Studio. If so, npmdoesn't override it. So you have to remove the previous deprecated tscinstalled command.

而且它可能是由像其他软件Visual Studio。如果是这样，npm不要覆盖它。因此，您必须删除以前不推荐使用的已tsc安装命令。

Run where tscto know its bin location. It should be in C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\in windows. Once found, delete the folder, and re-run npm install -g typescript. This should now install the last version of typescript.

运行where tsc以了解其垃圾箱位置。它应该C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\在窗口中。找到后，删除该文件夹，然后重新运行npm install -g typescript. 现在应该安装最新版本的打字稿。

The issue was in my code.

问题出在我的代码中。

In large code base, issue was not clear.

在大型代码库中，问题不明确。

A simplified code is below:

一个简化的代码如下：

Bad:

坏的：

 collection.insertMany(
    [[],
    function (err, result) {
    });

Good:

好的：

collection.insertMany(
    [],
    function (err, result) {
    });

That is, the first one has [[], instead of normal array []

也就是说，第一个有[[]，而不是普通的数组[]

TS error was not clear enough, and it showed error in the last line with });

TS错误不够清楚，最后一行用})显示错误；

Hope this helps.

希望这可以帮助。

I had today a similar error message. What was peculiar is that it did not break the Application. It was running smoothly but the command prompt (Windows machine) indicated there was an error. I did not update the Typescript version but found another culprit. It turned there was a tiny omission of symbol - closing ")", which I believe The Typescript is compensating for. Just for reference the code is the following:

我今天收到了类似的错误消息。奇怪的是它没有破坏应用程序。它运行顺利，但命令提示符（Windows 机器）指示存在错误。我没有更新 Typescript 版本，但发现了另一个罪魁祸首。原来有一点符号遗漏 - 关闭“）”，我相信 Typescript 正在弥补这一点。代码如下，仅供参考：

[new Object('First Characteristic','Second Characteristic',
'Third Characteristic'*] 

* notice here the ending ")" is missing.

Once brought back no more issues on the command prompt!

一旦在命令提示符下不再出现问题！

  this will install the latest version and then re-try.

• 删除C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0目录。

• 现在运行：

  npm install -g typescript 
  

  这将安装最新版本，然后重试。

I was injecting service like this:

我正在注入这样的服务：

private messageShowService MessageShowService

instead of:

代替：

private messageShowService: MessageShowService

and that was the reason of error, despite nothing related with ','was there.

这就是错误的原因，尽管与','那里没有任何关系。

If you're getting error TS1005: 'finally' expected., it means you forgot to implement catchafter try. Generally, it means the syntax you attempted to use was incorrect.

如果您得到error TS1005: 'finally' expected.，则意味着您忘记catch在try. 通常，这意味着您尝试使用的语法不正确。
