Jscript语法错误-代码800A03EA - Microsoft JScript编译-锯齿供应链- Windows 10

Question

尝试使用命令建立锯齿供应链，但得到以下错误。运行在版本为0.10.1的Windows 10膝上。我已经从https://github.com/hyperledger/sawtooth-supply-chain下载了这些文件，并按照readme.md文件进行安装。

当我查找文件‘/锯齿-供应链/分类帐_sync/index.js’时，我会得到一个javascript语法错误，代码800A03EA与源代码作为微软JScript编译错误。有人能帮忙吗？

Answer 1

我不知道上面的解决方案，但是如果您安装了一个VM (如VirtualBox )，然后在VirtualBox中运行带有Docker和docker的Sawtooth，您会发现它要容易得多。

Answer 2

我今天也在谷歌上搜索过。基于JScript / Microsoft的脚本主机无法处理ECMAScript类型语法或Regex功能。

对我来说，我发现这很可能是因为使用了关键字，例如：

• let。
• forEach
• exec

(最后两个用正则匹配器)。

顺便说一句:代码是以下几个方面的合并：

• regex101为JavaScript生成的内容，以及
• 这之类的东西。

最后，我放弃了JavaScript，转而使用了VBScript，因为我试图为regexes调用脚本代码，其中包含来自Automation的多个组，并在一次尝试中获得多个结果。
