Brownie无法找到deploy.py脚本

Question

我用Anaconda在我的系统(Windows)上安装了python，这可能是问题的根本原因。我正处于一个需要运行deploy.py脚本来部署契约的阶段，但是文件无法找到，什么也没有发生。

每次我运行brownie时，我都会首先得到一条信息：

INFO: Could not find files for the given pattern(s).

然后，Brownie运行，编译合同等，我得到了大量与ganache文件相关的文本。最后，我得到一个FileNotFoundError，表示系统找不到我想要运行的文件。代码如下：

PS C:\Users\nstei\Git Repos\my-frist-brownie-project> brownie run .\scripts\deploy.py
INFO: Could not find files for the given pattern(s).

  Solc version: 0.7.3

MyFristBrownieProject is the active project.

Answer 1

很难找到甘纳奇。您需要安装nodejs和npm，然后运行以下命令：

npm install -g ganache-cli

你应该好好去

Answer 2

在Windows20H2上，我也面临着同样的问题，我尝试使用npm install -g ganache-cli，但多次卸载和重新安装都不起作用。在那之后，我检查了我的节点版本，它是12.xx，这就是问题所在。我把它升级到14.18.0，现在布朗尼为我工作。https://nodejs.org/en/

Answer 3

当我打字快的时候，我会留下空白。

  brownie run scripts /fileName.py

它应该是

brownie run scripts/fileName.py
