安装 composer-cli 时出错

Question

我无法正确安装 composer-cli。我试过用自制软件和其他方法卸载节点和 npm。我收到有关 python 安装的错误。所以我继续安装 python2.7 并指示 npm 使用它。这似乎解决了那个特定的错误，但随后出现了其他错误。如果有人对此问题有经验，我将不胜感激。谢谢！

Answer 1

看起来它仍在使用 python3 安装。您可以尝试完全删除 python3 或从 shell 中禁用吗？

这是基于错误的结果：

$ python -c 'import sys; print "%s.%s.%s" % sys.version_info[:3];'
2.7.15
$ python3 -c 'import sys; print "%s.%s.%s" % sys.version_info[:3];'
  File "<string>", line 1
    import sys; print "%s.%s.%s" % sys.version_info[:3];
                               ^
SyntaxError: invalid syntax

Answer 2

OSX (Darwin 17.7.0) 附带 python 2.7 并且 npm 使用的许多底层脚本期望并使用 "Old Style" 字符串格式与 " %”。如果您已从 2000 年代后期升级到 Python 3+.

，则此方法无效

每次（重新）安装具有此问题的组件时，此问题都会不断弹出。反复卸载和重新安装 python 非常令人沮丧。

解决方法：暂时将 OSX 的原始 python 可执行文件放在 $PATH 的前面，运行你 npm install。它通常在 /usr/bin 所以试试：

$ GOODPATH=$PATH
$ export PATH=/usr/bin:$PATH
$ python --version
Python 2.7.10

npm install ....

$ export PATH=$GOODPATH
$ python --version
Python 3.7.2

同样的问题发生在运行 npm install -g composer-cli on macOS Mojave(10.14.3) 节点版本：v8.15.1， nvm 版本：0.33.0， npm 版本：6.4.1

发生错误，因为它正在使用 python3 安装。卸载 python3 不是一个好的选择所以我暂时将 python 默认路径更改为 OSX 的原始 pyhton 路径

  $ GOODPATH=$PATH
    $ export PATH=/usr/bin:$PATH
    $ python --version
    Python 2.7.10

然后使用https://hyperledger.github.io/composer/latest/installing/development-tools.html

中提到的命令安装composer-cli

并且在成功安装 composer-cli 后更改了默认 python 路径，因为它是以前的。

$ export PATH=$GOODPATH
$ python --version
Python 3.6.5 :: Anaconda, Inc.

Answer 4

我通过 =>

在我的 Ubuntu 18.04 机器上解决了同样的问题

正在 https://hyperledger.github.io/composer/latest/installing/installing-prereqs.html

安装先决条件

这表示->

curl -O https://hyperledger.github.io/composer/latest/prereqs-ubuntu.sh

然后 chmod u+x 先决条件-ubuntu.sh 最后=>

./prereqs-ubuntu.sh

然后重新启动终端并尝试安装 =>

npm install -g composer-cli@0.20

没有 su 或 sudo。我希望这会有所帮助:):)
